Based on the paragraph below, which are the most and least popular National Parks in the US? | The United States has 63 national parks, which are congressionally designated protected areas operated by the National Park Service, an agency of the Department of the Interior. National parks are designated for their natural beauty, unique geological features, diverse ecosystems, and recreational opportunities, typically "because of some outstanding scenic feature or natural phenomena." While legislatively all units of the National Park System are considered equal with the same mission, national parks are generally larger and more of a destination, and hunting and extractive activities are prohibited. National monuments, on the other hand, are also frequently protected for their historical or archaeological significance. Eight national parks (including six in Alaska) are paired with a national preserve, areas with different levels of protection that are administered together but considered separate units and whose areas are not included in the figures below. The 424 units of the National Park System can be broadly referred to as national parks, but most have other formal designations.
Thirty states have national parks, as do the territories of American Samoa and the U.S. Virgin Islands. The state with the most national parks is California with nine, followed by Alaska with eight, Utah with five, and Colorado with four. The largest national park is Wrangell–St. Elias in Alaska: at over 8 million acres (32,375 km2), it is larger than each of the nine smallest states. The next three largest parks are also in Alaska. The smallest park is Gateway Arch National Park, Missouri, at 91 acres (0.37 km2). The total area protected by national parks is approximately 52.2 million acres (211,000 km2), for an average of 829 thousand acres (3,350 km2) but a median of only 208 thousand acres (840 km2).
The national parks set a visitation record in 2017, with more than 84 million visitors and set a further record in 2018 with a 0.1% increase. Great Smoky Mountains National Park in North Carolina and Tennessee has been the most-visited park since 1944, and had over 14 million visitors in 2021. In contrast, only about 7,000 people visited the remote Gates of the Arctic National Park and Preserve in Alaska in 2021. | If we use number of visitors as a proxy for popularity then The Great Smoky Mountains National Park with over 14 million visitors in 2021 would rank as the most popular National Park. The least visited National Park is the Gates of the Arctic National Park and Preserve. Its lower visitation rate may have more to do with its remoteness than the Park's popularity. | closed_qa |
Spanish patatas bravas are potatoes served with a red sauce made with tomatoes and chilis. Could patatas bravas have existed in 1490? | Food historian Lois Ellen Frank calls potatoes, tomatoes, corn, beans, squash, chili, cacao, and vanilla the "magic eight" ingredients that were found and used only in the Americas before 1492 and were taken via the Columbian Exchange back to the Old World, dramatically transforming the cuisine there. According to Frank,
If we deconstruct that these foods were inherently native, then that means that the Italians didn't have the tomato, the Irish didn't have the potato, half the British National Dish—Fish and Chips—didn't exist. The Russians didn't have the potato, nor did they have vodka from the potato. There were no chiles in any Asian cuisine anywhere in the world, nor were there any chiles in any East Indian cuisine dishes, including curries. And the French had no confection using either vanilla or chocolate. So the Old World was a completely different place. | No, patatas bravas could not have existed in 1490. This is because in 1490 the Americas had not yet been visited by Europeans, and so Spaniards didn't have access to the potatoes, tomatoes or chilis present in the dish, because those plants are all from the Americas originally. | closed_qa |
Given the below reference text about Luftwaffe, tell me for how many years was this military organisation active officially in Germany? | The Luftwaffe was the aerial-warfare branch of the German Wehrmacht before and during World War II. Germany's military air arms during World War I, the Luftstreitkräfte of the Imperial Army and the Marine-Fliegerabteilung of the Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles which banned Germany from having any air force.
During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the Luftwaffe's existence was publicly acknowledged on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a Luftwaffe detachment sent to aid Nationalist forces in the Spanish Civil War, provided the force with a valuable testing ground for new tactics and aircraft. Partially as a result of this combat experience, the Luftwaffe had become one of the most sophisticated, technologically advanced, and battle-experienced air forces in the world when World War II broke out in September 1939. By the summer of 1939, the Luftwaffe had twenty-eight Geschwader (wings). The Luftwaffe also operated a paratrooper force known as the Fallschirmjäger.
The Luftwaffe proved instrumental in the German victories across Poland and Western Europe in 1939 and 1940. During the Battle of Britain, however, despite inflicting severe damage to the RAF's infrastructure and, during the subsequent Blitz, devastating many British cities, the German air force failed to batter the beleaguered British into submission. From 1942, Allied bombing campaigns gradually destroyed the Luftwaffe's fighter arm. From late 1942, the Luftwaffe used its surplus ground support and other personnel to raise Luftwaffe Field Divisions. In addition to its service in the West, the Luftwaffe operated over the Soviet Union, North Africa and Southern Europe. Despite its belated use of advanced turbojet and rocket-propelled aircraft for the destruction of Allied bombers, the Luftwaffe was overwhelmed by the Allies' superior numbers and improved tactics, and a lack of trained pilots and aviation fuel. In January 1945, during the closing stages of the Battle of the Bulge, the Luftwaffe made a last-ditch effort to win air superiority, and met with failure. With rapidly dwindling supplies of petroleum, oil, and lubricants after this campaign, and as part of the entire combined Wehrmacht military forces as a whole, the Luftwaffe ceased to be an effective fighting force.
After the defeat of Nazi Germany, the Luftwaffe was disbanded in 1946. During World War II, German pilots claimed roughly 70,000 aerial victories, while over 75,000 Luftwaffe aircraft were destroyed or significantly damaged. Of these, nearly 40,000 were lost entirely. The Luftwaffe had only two commanders-in-chief throughout its history: Hermann Göring and later Generalfeldmarschall Robert Ritter von Greim for the last two weeks of the war. | The Luftwaffe was officially active for about 11 years - 1935 to 1946. | closed_qa |
What is tollywood? | Telugu cinema, also known as Tollywood, is the segment of Indian cinema dedicated to the production of motion pictures in the Telugu language, widely spoken in the states of Andhra Pradesh and Telangana. Telugu cinema is based in Film Nagar, Hyderabad. As of 2021, Telugu cinema is the largest film industry in India in terms of box-office. Telugu films sold 23.3 crore (233 million) tickets in 2022, the highest among various film industries in India. | Tollywood is a nickname for movies made by Telugu cinema in India. | closed_qa |
What are all the different names for COVID-19 and which one is the most recommended? | During the initial outbreak in Wuhan, the virus and disease were commonly referred to as "coronavirus" and "Wuhan coronavirus", with the disease sometimes called "Wuhan pneumonia". In the past, many diseases have been named after geographical locations, such as the Spanish flu, Middle East respiratory syndrome, and Zika virus. In January 2020, the World Health Organization (WHO) recommended 2019-nCoV and 2019-nCoV acute respiratory disease as interim names for the virus and disease per 2015 guidance and international guidelines against using geographical locations or groups of people in disease and virus names to prevent social stigma. The official names COVID‑19 and SARS-CoV-2 were issued by the WHO on 11 February 2020 with COVID-19 being shorthand for "coronavirus disease 2019". The WHO additionally uses "the COVID‑19 virus" and "the virus responsible for COVID‑19" in public communications. | Here are a list of names for COVID-19 that were mentioned: coronavirus, Wuhan coronavirus, Wuhan pneumonia, 2019-nCoV, 2019-nCoV acute respiratory disease, COVID‑19, SARS-CoV-2, the COVID‑19 virus, the virus responsible for COVID‑19.
The official names COVID‑19 and SARS-CoV-2 were issued by the WHO on 11 February 2020, but they also use "the COVID‑19 virus" and "the virus responsible for COVID‑19" in public communications.
Based on this information, the most recommended name is COVID-19. | closed_qa |
Given this paragraph about magnesium, what is the element symbol of magnesium? | Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. | Mg is the element symbol of magnesium. | closed_qa |
Given these paragraphs about Natural hydrogen, can you name some of the countries where sources have been identified? | Natural hydrogen (known as white hydrogen), is naturally occurring molecular hydrogen on or in Earth (as opposed to hydrogen produced in the laboratory or in industry). The name white hydrogen distinguishes it from green hydrogen, which is produced from renewable energy sources, and from grey, brown or black hydrogen, which is obtained from fossil sources or from the electrolysis of water. Natural hydrogen may be renewable, non-polluting and allows for lower cost operation compared to industrial hydrogen. Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.
Origin of natural hydrogen
There are several sources of natural hydrogen:
- degassing of deep hydrogen from the Earth's crust and mantle;
- reaction of water with ultrabasic rocks (serpentinisation);
- contact of water with reducing agents in the Earth's mantle;
- interaction of water with freshly exposed rock surfaces (weathering);
- decomposition of hydroxyl ions in the structure of minerals;
- Natural radiolysis of water;
- decomposition of organic matter;
- biological activity
- Extraction
- Natural hydrogen is extracted from wells, mixed with other gases such as nitrogen or helium.
Several sources have been identified in France. Geologists Alain Prinzhofer and Eric Derville have demonstrated the existence of large reservoirs in a dozen countries, including Mali and the United States. However, their potential remains difficult to assess.
Numerous emanations on the ocean floor have been identified but are difficult to exploit. The discovery of a significant emergence in Russia in 2008 suggests the possibility of extracting native hydrogen in geological environments.
Geology
Natural hydrogen is generated continuously from a variety of natural sources. There are many known hydrogen emergences on mid-ocean ridges. Another of the known reactions, serpentinisation, occurs under the sea floor (in the oceanic crust).
Diagenetic origin (iron oxidation) in the sedimentary basins of cratons, notably in Russia. Other sources are being explored, such as mantle hydrogen, or hydrogen from radiolysis (natural electrolysis) or from bacterial activity. In France, the Alps and Pyrenees are suitable for exploitation. New Caledonia has hyperalkaline sources that show dihydrogen emissions. A large accumulation of natural hydrogen was discovered in Bourakebougou (Mali).
Characteristics
Dihydrogen is very soluble in fresh water, especially at depth (solubility increases with pressure).

Based on the provided text, what technology rendered Extended ASCII obsolete? | Extended ASCII is a repertoire of character encodings that include (most of) the original 96 ASCII character set, plus up to 128 additional characters. There is no formal definition of "extended ASCII", and even use of the term is sometimes criticized, because it can be mistakenly interpreted to mean that the American National Standards Institute (ANSI) had updated its ANSI X3.4-1986 standard to include more characters, or that the term identifies a single unambiguous encoding, neither of which is the case.
The ISO standard ISO 8859 was the first international standard to formalize a (limited) expansion of the ASCII character set: of the many language variants it encoded, ISO 8859-1 ("ISO Latin 1") – which supports most Western European languages – is best known in the West. There are many other extended ASCII encodings (more than 220 DOS and Windows codepages). EBCDIC ("the other" major character code) likewise developed many extended variants (more than 186 EBCDIC codepages) over the decades.
The technology has largely been rendered technically obsolete by Unicode, which has code points for all the characters encoded in the various attempts to extend ASCII. All modern operating systems use this technology. Nevertheless, the topic remains important in the history of computing. | Unicode rendered extended ASCII obsolete. | closed_qa |
Given this paragraph about magnesium, what is the boiling point of magnesium in celsius? | Elemental magnesium is a gray-white lightweight metal, two-thirds the density of aluminium. Magnesium has the lowest melting (923 K (650 °C)) and the lowest boiling point 1,363 K (1,090 °C) of all the alkaline earth metals. | The boiling point of magnesium is 1,090 °C. | closed_qa |
How many American's signed the Declaration of Independence? | The Declaration of Independence was signed by 56 of America's Founding Fathers, who were Second Continental Congress delegates from New Hampshire, Massachusetts Bay, Rhode Island and Providence Plantations, Connecticut, New York, New Jersey, Pennsylvania, Maryland, Delaware, Virginia, North Carolina, South Carolina, and Georgia. The Declaration became one of the most circulated and widely reprinted documents in early American history. | 56 | closed_qa |
what is snow skiing | Skiing is the use of skis to glide on snow. Variations of purpose include basic transport, a recreational activity, or a competitive winter sport.

In one sentence, what is this paragraph conveying? | A person's last words, their final articulated words stated prior to death or as death approaches, are often recorded because of the decedent's fame, but sometimes because of interest in the statement itself. (People dying of illness are frequently inarticulate at the end, and in such cases their actual last utterances may not be recorded or considered very important.) Last words may be recorded accurately, or, for a variety of reasons, may not. Reasons can include simple error or deliberate intent. Even if reported wrongly, putative last words can constitute an important part of the perceived historical records or demonstration of cultural attitudes toward death at the time. | The paragraph talk about the finals recorded words a person says at the time of death, and how they could be historically or culturally significance. | closed_qa |
here is a blurb about byte pair encoding for encryption, what benefits does this concept have besides compression? | Byte pair encoding (BPE) or digram coding is a simple and robust form of data compression in which the most common pair of contiguous bytes of data in a sequence are replaced with a byte that does not occur within the sequence. A lookup table of the replacements is required to rebuild the original data. The algorithm was first described publicly by Philip Gage in a February 1994 article "A New Algorithm for Data Compression" in the C Users Journal.
A variant of the technique has shown to be useful in several natural language processing (NLP) domains, for applications such as tokenisation, as seen in Google's SentencePiece and OpenAI's GPT-3. Here, the goal is not data compression, but tokenisation of text in a given language to produce a variable sequence of terms from a fixed-size vocabulary of tokens. Typically, most words will be encoded as a single token, while rare words will be encoded as a sequence of a few tokens, where these tokens represent meaningful word parts. This translation of text into tokens can be found by variants of byte pair encoding, such as subword units.
Byte pair encoding lends itself to NLP tasks due to its simplicity and speed; BPE is suitably effective for the tokenisation of terms, does not require large computational overheads, and remains consistent, making it reliable. | An alternate use for byte pair encoding besides compression would be tokenization. Tokenization can be used in Natural Language Processing to encode tokens of words for simplicity and speed in NLP tasks. | closed_qa |
Name someone who helped to stash national treasures during a war, so irreplaceable items would not fall into the hands of the enemy or become lost | Evdokia Reshetnik was a Ukrainian zoologist and ecologist. She was a specialist in the mole-rats and ground squirrels of Ukraine, and was the first scientist to describe the sandy blind mole-rat of southern Ukraine in 1939. She played a key role in keeping the National Museum of Natural History at the National Academy of Sciences of Ukraine operable in the inter-war and immediate post-war periods, in spite of arrests by both the Gestapo and Soviet authorities. She was one of the people involved in hiding specimens of the museum to prevent them being taken by the Germans. She is known for arguing that ecology, species distribution, populations, utility, and variability, should be weighed before making determinations that labeled certain animals as pests and harmful to the environment. Though she was responsible for maintaining the historiography of scientific development in Ukraine, her own legacy was lost until the twenty-first century. | Evdokia Reshetnik, a Ukranian zoologist and ecologist, helped squirrel away natural history artifacts from a Ukranian museum of Natural History, keeping them from falling into the hands of the Germans.

What is an "El Niño" weather pattern? | El Niño (/ɛl ˈniːnjoʊ/ el NEEN-yoh, Spanish: [el ˈniɲo]; lit. 'The Boy') is the warm phase of the El Niño–Southern Oscillation (ENSO) and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific (approximately between the International Date Line and 120°W), including the area off the Pacific coast of South America. The ENSO is the cycle of warm and cold sea surface temperature (SST) of the tropical central and eastern Pacific Ocean.
El Niño is accompanied by high air pressure in the western Pacific and low air pressure in the eastern Pacific. El Niño phases are known to last close to four years; however, records demonstrate that the cycles have lasted between two and seven years. During the development of El Niño, rainfall develops between September–November.
It should be noted that the cool phase of ENSO is Spanish: La Niña, lit. 'The Girl', with SSTs in the eastern Pacific below average, and air pressure high in the eastern Pacific and low in the western Pacific. The ENSO cycle, including both El Niño and La Niña, causes global changes in temperature and rainfall. | El Niño (/ɛl ˈniːnjoʊ/ el NEEN-yoh, Spanish: [el ˈniɲo]; lit.

What is a nickname of Jiang Zemin | Moha (Chinese: 膜蛤; pinyin: Mó Há, pronounced [muǒ.xǎ]), literally "admiring toad" or "toad worship", is an internet meme spoofing Jiang Zemin, former General Secretary of the Chinese Communist Party and paramount leader. It originated among the netizens in mainland China and has become a subculture on the Chinese internet. According to another explanation, it comes from China's social media Baidu Tieba. In the culture, Jiang is nicknamed há, or "toad", because of his supposed resemblance to a toad. Netizens who móhá (worship the toad) call themselves "toad fans", "toad lovers" or "toad worshippers" (simplified Chinese: 蛤丝; traditional Chinese: 蛤絲), or "mogicians" (膜法师; 膜法師) which is a wordplay on mófǎshī (魔法师; 魔法師, magician) in Mandarin.[note 1]
Another nickname for Jiang is "elder" or "senior" (长者; 長者; Zhǎngzhě), because he once called himself an "elder" or "senior" when he was berating Hong Kong journalist Sharon Cheung who questioned him. A video clip recording this event spread on the internet and led to the rise of the culture, which later greatly rose in popularity around 2014, when Hong Kong was experiencing a period of political instability. Initially, netizens extracted Jiang's quotes from the video and imitated his wording and tone, for parody and insult. However, as the culture developed, some imitations have taken to carrying affection toward him. The quotes for imitation have also evolved to include what he said during his leadership, and in his personal life. | Elder or senior | closed_qa |
Based on the reference text, what colors do the Tampa Bay Rowdies wear and what stadium do they play in? | The Tampa Bay Rowdies are an American professional soccer team based in St. Petersburg, Florida. The club was founded in 2008 and first took the pitch in 2010. Since 2017, the Rowdies have been members of the USL Championship in the second tier of the American soccer pyramid. They formerly played in USSF Division 2 (in 2010) and the North American Soccer League (NASL) (from 2011 to 2016), which were also second-tier leagues. The Rowdies play their home games at Al Lang Stadium on St. Petersburg's downtown waterfront.
The current club is a phoenix club of the original Tampa Bay Rowdies, who were active from 1975 until 1993, most notably in the original North American Soccer League. It shares its name, logo, and some of its club culture with the original club. The owners of the current club announced their intention to use the old Rowdies' trademarks at its introductory press conference in 2008. However, licensing issues forced the club to use the name FC Tampa Bay until December 2011, when it gained full rights to the Rowdies name and other intellectual property. The current Rowdies have always used the same green and yellow color scheme and "hoops" as the original team, even when they could not yet use the Rowdies name.
The Rowdies captured the NASL championship in Soccer Bowl 2012, and their team shield includes two stars: one for their 2012 win and one for the 1975 Soccer Bowl championship won by the original Rowdies. The club has had a long-standing rivalry with the Fort Lauderdale Strikers, with whom they have contested the Florida Derby since the original Rowdies and Strikers first met in 1977. The Rowdies were also named co-league champions in 2020 after winning the USL Regular Season title and Eastern Conference Championship, but the title game was canceled due to COVID-19. They were Eastern Conference Champions again in 2021, but lost in the title game.

Given a reference text about a snowball effect, tell me how it applies to aerospace engineering. | A snowball effect is a process that starts from an initial state of small significance and builds upon itself (an exacerbating feedback), becoming larger (graver, more serious), and also perhaps potentially dangerous or disastrous (a vicious circle), though it might be beneficial instead (a virtuous circle). This is a cliché in cartoons and modern theatrics, and it is also used in psychology.
The common analogy is with the rolling of a snowball down a snow-covered hillside. As it rolls the ball will pick up more snow, gaining more mass and surface area, and picking up even more snow and momentum as it rolls along.
In aerospace engineering, it is used to describe the multiplication effect in an original weight saving. A reduction in the weight of the fuselage will require less lift, meaning the wings can be smaller. Hence less thrust is required and therefore smaller engines, resulting in a greater weight saving than the original reduction. This iteration can be repeated several times, although the decrease in weight gives diminishing returns.
The startup process of a feedback electronic oscillator, when power to the circuit is switched on, is a technical application of the snowball effect. Electronic noise is amplified by the oscillator circuit and returned to its input filtered to contain primarily the selected (desired) frequency, gradually getting stronger in each cycle, until a steady-state oscillation is established, when the circuit parameters satisfy the Barkhausen stability criterion. | The snowball effect is used to describe the multiplication effect in an original weight saving in aerospace engineering. | closed_qa |

When and where was Nero born? | Nero Claudius Caesar Augustus Germanicus (/ˈnɪəroʊ/ NEER-oh; born Lucius Domitius Ahenobarbus; 15 December AD 37 – 9 June AD 68), was the fifth Roman emperor and final emperor of the Julio-Claudian dynasty, reigning from AD 54 until his death in AD 68. He was adopted by the Roman emperor Claudius at the age of 13 and succeeded him on the throne. Nero was popular with the members of his Praetorian Guard and lower-class commoners in Rome and its provinces, but he was deeply resented by the Roman aristocracy. Most contemporary sources describe him as tyrannical, self-indulgent, and debauched. After being declared a public enemy by the Roman Senate, he committed suicide at age 30.
Nero was born at Antium in AD 37, the son of Gnaeus Domitius Ahenobarbus and Agrippina the Younger, a great-granddaughter of the emperor Augustus. When Nero was two years old, his father died. His mother married the emperor Claudius, who eventually adopted Nero as his heir; when Claudius died in AD 54, Nero became emperor with the support of the Praetorian Guard and the Senate. In the early years of his reign Nero was advised and guided by his mother Agrippina, his tutor Seneca the Younger, and his praetorian prefect Sextus Afranius Burrus, but he soon sought to rule independently and to rid himself of restraining influences. His power struggle with his mother was eventually resolved when he had her murdered. Roman sources also implicate Nero in the deaths of his wife Claudia Octavia – supposedly so that he could marry Poppaea Sabina – and of his step brother Britannicus.
Nero's practical contributions to Rome's governance focused on diplomacy, trade, and culture. He ordered the construction of amphitheaters, and promoted athletic games and contests. He also made public appearances as an actor, poet, musician, and charioteer, which scandalised his aristocratic contemporaries as these occupations were usually the domain of slaves, public entertainers and infamous persons. The provision of such entertainments made Nero popular among lower-class citizens, but his performances undermined the Imperial dignity. The costs involved were borne by local elites either directly or through taxation, and were much resented.
During Nero's reign, the general Corbulo fought the Roman–Parthian War of 58–63, and made peace with the hostile Parthian Empire. The Roman general Suetonius Paulinus quashed a major revolt in Britain led by the Iceni's queen Boudica. The Bosporan Kingdom was briefly annexed to the empire, and the First Jewish–Roman War began. When the Roman senator Vindex rebelled, with support from the eventual Roman emperor Galba, Nero was declared a public enemy and condemned to death in absentia. He fled Rome, and on 9 June AD 68 he committed suicide. His death sparked a brief period of civil war known as the Year of the Four Emperors.
Most Roman sources offer overwhelmingly negative assessments of his personality and reign. The historian Tacitus claims the Roman people thought him compulsive and corrupt. Suetonius tells that many Romans believed that the Great Fire of Rome was instigated by Nero to clear land for his planned "Golden House". Tacitus claims that Nero seized Christians as scapegoats for the fire and had them burned alive, seemingly motivated not by public justice but by personal cruelty. Some modern historians question the reliability of the ancient sources on Nero's tyrannical acts, considering his popularity among the Roman commoners. In the eastern provinces of the Empire, a popular legend arose that Nero had not died and would return. After his death, at least three leaders of short-lived, failed rebellions presented themselves as "Nero reborn" in order to gain popular support.
Early life
Nero was born Lucius Domitius Ahenobarbus on 15 December 37 AD in Antium (modern Anzio).: 87 He was an only-child, the son of the politician Gnaeus Domitius Ahenobarbus and Agrippina the Younger. His mother Agrippina was the sister of the third Roman emperor Caligula.: 5 Nero was also the great-great-grandson of former emperor Augustus (descended from Augustus' only daughter, Julia).: 2
The ancient biographer Suetonius, who was critical of Nero's ancestors, wrote that emperor Augustus had reproached Nero's grandfather for his unseemly enjoyment of violent gladiator games. According to Jürgen Malitz, Suetonius tells that Nero's father was known to be "irascible and brutal", and that both "enjoyed chariot races and theater performances to a degree not befitting their position".: 3 Suetonius also mentions that when Nero's father Domitius was congratulated by his friends for the birth of his son, he replied that any child born to him and Agrippina would have a detestable nature and become a public danger.
Domitius died in 40 AD. A few years before his father's death, his father was involved in a serious political scandal.: 3 His mother and his two surviving sisters, Agrippina and Julia Livilla, were exiled to a remote island in the Mediterranean Sea.: 4 His mother was said to have been exiled for plotting to overthrow the emperor Caligula. Nero's inheritance was taken from him, and he was sent to live with his paternal aunt Domitia Lepida the Younger, the mother of later emperor Claudius's third wife, Messalina.: 11

After Caligula's death, Claudius became the new Roman Emperor. Nero's mother married Claudius in 49 AD, becoming his fourth wife. By February, 49 AD, his mother had persuaded Claudius to adopt her son Nero.
After Nero's adoption by the emperor, "Claudius" became part of his name: Nero Claudius Caesar Drusus Germanicus. Claudius had gold coins issued to mark the adoption.: 119 Classics professor Josiah Osgood has written that "the coins, through their distribution and imagery alike, showed that a new Leader was in the making.": 231 However, David Shotter noted that, despite events in Rome, Nero's step-brother Britannicus was more prominent in provincial coinages during the early 50s.: 52

Nero formally entered public life as an adult in 51 AD at approximately 14 years old.: 51 When he turned 16, Nero married Claudius' daughter (his step-sister), Claudia Octavia. Between the years 51 AD and 53 AD, he gave several speeches on behalf of various communities, including the Ilians; the Apameans (requesting a five-year tax reprieve after an earthquake); and the northern colony of Bologna, after their settlement had suffered a devastating fire.: 231
Claudius died in 54 AD; many ancient historians claim that he was poisoned by Agrippina. Shotter has written that "Claudius' death in 54 AD has usually been regarded as an event hastened by Agrippina due to signs that Claudius was showing a renewed affection for his natural son". He also notes that among ancient sources, the Roman historian Josephus was uniquely reserved in describing the poisoning as a rumor.: 53
Contemporary sources differ in their accounts of the poisoning. Tacitus says that the poison-maker Locusta prepared the toxin, which was served to the Emperor by his servant Halotus. Tacitus also writes that Agrippina arranged for Claudius' doctor Xenophon to administer poison, in the event that the Emperor survived.: 53 Suetonius differs in some details, but also implicates Halotus and Agrippina. Like Tacitus, Cassius Dio writes that the poison was prepared by Locusta, but in Dio's account it is administered by Agrippina instead of Halotus. In Apocolocyntosis, Seneca the Younger does not mention mushrooms at all.: 54 Agrippina's involvement in Claudius' death is not accepted by all modern scholars.: 589
Before Claudius' death, Agrippina had maneuvered to remove Claudius' sons' tutors in order to replace them with tutors that she had selected. She was also able to convince Claudius to replace two prefects of the Praetorian Guard (who were suspected of supporting Claudius' son) with Afranius Burrus (Nero's future guide).: 13 Since Agrippina had replaced the guard officers with men loyal to her, Nero was subsequently able to assume power without incident.: 417 | Nero was born at Antium (modern day Anzio, Italy) on December, 15th 37 AD. | closed_qa |
From the paragraph about the painting, "The Little Street", tell me the painting's significance with reference to the Dutch Golden Age in that period. | The Little Street (Het Straatje) is a painting by the Dutch painter Johannes Vermeer, executed c. 1657-1658. It is exhibited at the Rijksmuseum of Amsterdam, and signed, below the window in the lower left-hand corner, "I V MEER". | Vermeer's "The Little Street" is significant in the context of the Dutch Golden Age movement as it depicts a typical aspect of life in a Dutch Golden Age town during the 17th century. It is one of only two known Vermeer paintings of views of Delft, the others being "View of Delft". Its attention to detail, the use of light, and the realistic portrayal of everyday life are characteristic of the Dutch Golden Age movement's focus on realism and domesticity in art. | closed_qa |
Given this paragraph about John C. Young, where did he go to college? | John Clarke Young (August 12, 1803 – June 23, 1857) was an American educator and pastor who was the fourth president of Centre College in Danville, Kentucky. A graduate of Dickinson College and Princeton Theological Seminary, he entered the ministry in Lexington, Kentucky, in 1828. He accepted the presidency of Centre College in 1830, holding the position until his death in 1857, making him the longest-serving president in the college's history. He is regarded as one of the college's best presidents, as he increased the endowment of the college more than five-fold during his term, and increased the graduating class size from two students in his first year to forty-seven in his final year. | Dickinson College and Princeton Theological Seminary | closed_qa |
According to the following paragraph on LeBron James, how did he announce joining the Miami Heat? | James grew up playing basketball for St. Vincent–St. Mary High School in his hometown of Akron, Ohio. He was heavily touted by the national media as a future NBA superstar. A prep-to-pro, he was selected by the Cleveland Cavaliers with the first overall pick of the 2003 NBA draft. Named the 2004 NBA Rookie of the Year, he soon established himself as one of the league's premier players, leading the Cavaliers to their first NBA Finals appearance in 2007 and winning the NBA MVP award in 2009 and 2010. After failing to win a championship with Cleveland, James left in 2010 as a free agent to join the Miami Heat; this was announced in a nationally televised special titled The Decision and is among the most controversial free agency moves in sports history. | LeBron James announced his move from the Cleveland Cavaliers to the Miami Heat in a television special called "The Decision" that was televised nationally. | closed_qa |
Give this paragraph about TCP/IP, what are the four abstraction laters? | The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). Early versions of this networking model were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA.
The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to highest, the layers are the link layer, containing communication methods for data that remains within a single network segment (link); the internet layer, providing internetworking between independent networks; the transport layer, handling host-to-host communication; and the application layer, providing process-to-process data exchange for applications.
The technical standards underlying the Internet protocol suite and its constituent protocols are maintained by the Internet Engineering Task Force (IETF). The Internet protocol suite predates the OSI model, a more comprehensive reference framework for general networking systems. | From lowest to highest, the layers are:
- link layer, containing communication methods for data that remains within a single network segment (link)
- the internet layer, providing internetworking between independent networks;
- the transport layer, handling host-to-host communication;
- the application layer, providing process-to-process data exchange for applications. | closed_qa |

According to this paragraph, what was the most common type of castle in England following the Norman Conquest? | There are nine castles in Greater Manchester, a metropolitan county in North West England. They consist of four motte-and-bailey castles, three fortified manor houses, an enclosure castle, and a possible shell keep. A motte-and-bailey castle is characterised by two elements: the motte is an artificial mound with a wooden stockade and stronghold on top, usually a stone keep or tower, while the bailey is a defended enclosure adjacent to the motte, typically enclosed by a ditch and a bank topped by a timber palisade or stone wall. Motte-and-bailey castles were the most common type of castle in England following the Norman Conquest. A shell keep was a motte with a stone wall rather than a wooden stockade on top; there would have been no tower within the walls. Four of Greater Manchester's castles are scheduled monuments: Buckton, Bury, Radcliffe Tower, and Watch Hill. A scheduled monument is a "nationally important" archaeological site or historic building, given protection against unauthorised change. | According to this text, the Motte-and-bailey castles were the most common following the Norman Conquest. | closed_qa |
Who tends to participates in hackathons? | A hackathon (also known as a hack day, hackfest, datathon or codefest; a portmanteau of hacking and marathon) is an event where people engage in rapid and collaborative engineering over a relatively short period of time such as 24 or 48 hours. They are often run using agile software development practices, such as sprint-like design wherein computer programmers and others involved in software development, including graphic designers, interface designers, product managers, project managers, domain experts, and others collaborate intensively on engineering projects, such as software engineering.
The goal of a hackathon is to create functioning software or hardware by the end of the event. Hackathons tend to have a specific focus, which can include the programming language used, the operating system, an application, an API, or the subject and the demographic group of the programmers. In other cases, there is no restriction on the type of software being created or the design of the new system. | Computer programmers and others involved in software development, including graphic designers, interface designers, product managers, project managers, domain experts, and others tend to participate in hackathons.

Why did the Sahara experience a period of rapid desertification? | The size of the Sahara has historically been extremely variable, with its area rapidly fluctuating and at times disappearing depending on global climatic conditions. At the end of the Ice ages, estimated to have been around 10,500 BCE, the Sahara had again become a green fertile valley, and its African populations returned from the interior and coastal highlands in sub-Saharan Africa, with rock art paintings depicting a fertile Sahara and large populations discovered in Tassili n'Ajjer dating back perhaps 10 millennia. However, the warming and drying climate meant that by 5000 BCE, the Sahara region was becoming increasingly dry and hostile. Around 3500 BCE, due to a tilt in the earth's orbit, the Sahara experienced a period of rapid desertification. The population trekked out of the Sahara region towards the Nile Valley below the Second Cataract where they made permanent or semi-permanent settlements. A major climatic recession occurred, lessening the heavy and persistent rains in Central and Eastern Africa. Since this time, dry conditions have prevailed in Eastern Africa and, increasingly during the last 200 years, in Ethiopia. | Sahara experienced a period of rapid desertification due to a tilt in the earth's orbit. | closed_qa |
Given this reference text about Neonatology, tell me which specialty it is related to, and where it is typically practiced. | Neonatology is a subspecialty of pediatrics that consists of the medical care of newborn infants, especially the ill or premature newborn. It is a hospital-based specialty, and is usually practiced in neonatal intensive care units (NICUs). The principal patients of neonatologists are newborn infants who are ill or require special medical care due to prematurity, low birth weight, intrauterine growth restriction, congenital malformations (birth defects), sepsis, pulmonary hypoplasia or birth asphyxia. | Neonatology is a subspecialty of pediatrics, which is typically practiced in a hospital's Neonatal Intensive Care Unit, often referred to as a NICU. | closed_qa |
What is parkrun | Parkrun (stylised as parkrun) is a collection of 5-kilometre (3.1 mi) events for walkers, runners and volunteers that take place every Saturday morning at more than 2,000 locations in 22 countries across six continents. Junior Parkrun (stylised as junior parkrun) is a spin-off event that provides a 2 kilometres (1+1⁄4 mi) event for children aged 4–14 on a Sunday morning. Parkrun events are free to enter and are delivered by volunteers, supported by a small group of staff at its headquarters. | Parkrun is a community event that takes place each Saturday morning where entrants walk, jog, or run a 5-kilometre course. Events take place at a range of general locations including parks, forests, rivers, lakes, beaches, and nature reserves. The first ever parkrun event took place on 2 October 2004 in Bushy Park, London involving 13 runners.

When he lived in the mountains of Alaska, was Richard Proenneke in full autonomy? | Richard Louis Proenneke (/ˈprɛnəkiː/; May 4, 1916 – April 20, 2003) was an American self-educated naturalist, conservationist, writer, and wildlife photographer who, from the age of about 51, lived alone for nearly thirty years (1968–1998) in the mountains of Alaska in a log cabin that he constructed by hand near the shore of Twin Lakes. Proenneke hunted, fished, raised and gathered much of his own food, and also had supplies flown in occasionally. He documented his activities in journals and on film, and also recorded valuable meteorological and natural data. The journals and film were later used by others to write books and produce documentaries about his time in the wilderness. | No, he was getting some of his food by plane. | closed_qa |
What is Sinking Sand? | Quicksand, also known as sinking sand, is a colloid consisting of fine granular material (such as sand, silt or clay) and water. It forms in saturated loose sand when the sand is suddenly agitated. When water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support weight. Quicksand can form in standing water or in upward flowing water (as from an artesian spring). In the case of upward flowing water, forces oppose the force of gravity and suspend the soil particles. | Sinking Sand is most commonly known as Quicksand. | closed_qa |
How long does it typically take a battery storage power station to transition to full power from standby? | A battery storage power station is a type of energy storage power station that uses a group of batteries to store electrical energy. Battery storage is the fastest responding dispatchable source of power on electric grids, and it is used to stabilise those grids, as battery storage can transition from standby to full power in under a second to deal with grid contingencies.
At full rated power, battery storage power stations are generally designed to output for up to a few hours. Battery storage can be used for short-term peak power and ancillary services, such as providing operating reserve and frequency control to minimize the chance of power outages. They are often installed at, or close to, other active or disused power stations and may share the same grid connection to reduce costs. Since battery storage plants require no deliveries of fuel, are compact compared to generating stations and have no chimneys or large cooling systems, they can be rapidly installed and placed if necessary within urban areas, close to customer load. | Under a second | closed_qa |
Based on the reference text, what does the champion of the Masters Tournament receive? | The Masters Tournament
The tournament has a number of traditions. Since 1949, a green jacket has been awarded to the champion, who must return it to the clubhouse one year after his victory, although it remains his personal property and is stored with other champions' jackets in a specially designated cloakroom. In most instances, only a first-time and currently reigning champion may remove his jacket from the club grounds. A golfer who wins the event multiple times uses the same green jacket awarded upon his initial win (unless they need to be re-fitted with a new jacket). The Champions Dinner, inaugurated by Ben Hogan in 1952, is held on the Tuesday before each tournament, and is open only to past champions and certain board members of the Augusta National Golf Club. Beginning in 1963, legendary golfers, usually past champions, have hit an honorary tee shot on the morning of the first round to commence play. These have included Fred McLeod, Jock Hutchinson, Gene Sarazen, Sam Snead, Byron Nelson, Arnold Palmer, Jack Nicklaus, Gary Player, Lee Elder, and Tom Watson. Since 1960, a semi-social contest at the par-3 course has been played on Wednesday, the day before the first round. | The champion of the Masters Tournament receives a green jacket.

Tell me when Silvio Berlusconi was born, how long has he been Prime Minister in Italy and what his nickname is | Silvio Berlusconi (/ˌbɛərlʊˈskoʊni/ BAIR-luu-SKOH-nee; Italian: [ˈsilvjo berluˈskoːni] (listen); born 29 September 1936) is an Italian media tycoon and politician who served as Prime Minister of Italy in four governments from 1994 to 1995, 2001 to 2006 and 2008 to 2011. He was a member of the Chamber of Deputies from 1994 to 2013, and has served as a member of the Senate of the Republic since 2022, and previously from March to November 2013, and as a Member of the European Parliament (MEP) since 2019, and previously from 1999 to 2001.
Berlusconi is the controlling shareholder of Mediaset and owned the Italian football club A.C. Milan from 1986 to 2017. He is nicknamed Il Cavaliere (The Knight) for his Order of Merit for Labour.
The Order of Merit for Labour (Italian: Ordine al Merito del Lavoro) is an Italian order of chivalry that was founded in 1923 by King Vittorio Emanuele III. It is awarded to those "who have been singularly meritorious" in agriculture, industry and commerce, crafts, lending and insurance. It is a continuation of the earlier Ordine al Merito Agrario, Industriale e Commerciale founded in 1901. Members of the order may use the title Cavaliere del lavoro.
He voluntarily resigned from this order in March 2014. In 2018, Forbes ranked him as the 190th richest man in the world with a net worth of US$8 billion. In 2009, Forbes ranked him 12th in the list of the World's Most Powerful People due to his domination of Italian politics throughout more than twenty years at the head of the centre-right coalition.
Berlusconi was Prime Minister for nine years in total, making him the longest serving post-war Prime Minister of Italy, and the third longest-serving since Italian unification, after Benito Mussolini and Giovanni Giolitti. He was the leader of the centre-right party Forza Italia from 1994 to 2009, and its successor party The People of Freedom from 2009 to 2013. Since November 2013, he has led a revived Forza Italia. Berlusconi was the senior G8 leader from 2009 until 2011, and he currently holds the record for hosting G8 summits (having hosted three summits in Italy). After serving nearly 19 years as a member of the Chamber of Deputies, the country's lower house, he became a member of the Senate following the 2013 Italian general election. | Silvio Berlusconi was born on September 29, 1936 and has been in charge as Prime Minister in Italy for a total of 9 years (from 1994 to 1995, 2001 to 2006 and 2008 to 2011).

When was Franz Kafka born and who was he? | Franz Kafka (3 July 1883 – 3 June 1924) was a German-speaking Bohemian novelist and short-story writer based in Prague, who is widely regarded as one of the major figures of 20th-century literature. His work fuses elements of realism and the fantastic. It typically features isolated protagonists facing bizarre or surrealistic predicaments and incomprehensible socio-bureaucratic powers. It has been interpreted as exploring themes of alienation, existential anxiety, guilt, and absurdity. His best known works include the short story "The Metamorphosis" and novels The Trial and The Castle. The term Kafkaesque has entered English to describe absurd situations, like those depicted in his writing. | Franz Kafka was born on 3 July 1883, and was a German-speaking Bohemian novelist and short-story writer based in Prague. | closed_qa |
How to play tic-tac-toe | There is no universally-agreed rule as to who plays first, but in this article the convention that X plays first is used.
Players soon discover that the best play from both parties leads to a draw. Hence, tic-tac-toe is often played by young children who may not have discovered the optimal strategy.
Because of the simplicity of tic-tac-toe, it is often used as a pedagogical tool for teaching the concepts of good sportsmanship and the branch of artificial intelligence that deals with the searching of game trees. It is straightforward to write a computer program to play tic-tac-toe perfectly or to enumerate the 765 essentially different positions (the state space complexity) or the 26,830 possible games up to rotations and reflections (the game tree complexity) on this space. If played optimally by both players, the game always ends in a draw, making tic-tac-toe a futile game. | Tic-tac-toe is played on a three-by-three grid by two players, who alternately place the marks X and O in one of the nine spaces in the grid. Tic-tac-toe (American English), noughts and crosses (Commonwealth English), or Xs and Os (Canadian or Irish English) is a paper-and-pencil game for two players who take turns marking the spaces in a three-by-three grid with X or O. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row is the winner. It is a solved game, with a forced draw assuming best play from both players. | closed_qa |
Given this paragraph about the Cold War, why did the Soviets pull out of their war in Afghanistan? | After World War II, parts of Eastern and Central Europe, including East Germany and eastern parts of Austria were occupied by Red Army according to the Potsdam Conference. Dependent communist governments were installed in the Eastern Bloc satellite states. After becoming the world's second nuclear power, the Soviet Union established the Warsaw Pact alliance, and entered into a struggle for global dominance, known as the Cold War, with the rivaling United States and NATO. After Stalin's death in 1953 and a short period of collective rule, the new leader Nikita Khrushchev denounced Stalin and launched the policy of de-Stalinization, releasing many political prisoners from the Gulag labor camps. The general easement of repressive policies became known later as the Khrushchev Thaw. At the same time, Cold War tensions reached its peak when the two rivals clashed over the deployment of the United States Jupiter missiles in Turkey and Soviet missiles in Cuba.
In 1957, the Soviet Union launched the world's first artificial satellite, Sputnik 1, thus starting the Space Age. Russian cosmonaut Yuri Gagarin became the first human to orbit the Earth, aboard the Vostok 1 manned spacecraft on 12 April 1961. Following the ousting of Khrushchev in 1964, another period of collective rule ensued, until Leonid Brezhnev became the leader. The era of the 1970s and the early 1980s was later designated as the Era of Stagnation. The 1965 Kosygin reform aimed for partial decentralisation of the Soviet economy. In 1979, after a communist-led revolution in Afghanistan, Soviet forces invaded the country, ultimately starting the Soviet–Afghan War. In May 1988, the Soviets started to withdraw from Afghanistan, due to international opposition, persistent anti-Soviet guerrilla warfare, and a lack of support by Soviet citizens.
From 1985 onwards, the last Soviet leader Mikhail Gorbachev, who sought to enact liberal reforms in the Soviet system, introduced the policies of glasnost (openness) and perestroika (restructuring) in an attempt to end the period of economic stagnation and to democratise the government. This, however, led to the rise of strong nationalist and separatist movements across the country. Prior to 1991, the Soviet economy was the world's second-largest, but during its final years, it went into a crisis.
By 1991, economic and political turmoil began to boil over as the Baltic states chose to secede from the Soviet Union. On 17 March, a referendum was held, in which the vast majority of participating citizens voted in favour of changing the Soviet Union into a renewed federation. In June 1991, Boris Yeltsin became the first directly elected president in Russian history when he was elected president of the Russian SFSR. In August 1991, a coup d'état attempt by members of Gorbachev's government, directed against Gorbachev and aimed at preserving the Soviet Union, instead led to the end of the Communist Party of the Soviet Union. On 25 December 1991, following the dissolution of the Soviet Union, along with contemporary Russia, fourteen other post-Soviet states emerged. | The Soviets withdrew from the Soviet-Afghan War beginning in May 1988 due to international opposition, persistent anti-Soviet guerrilla warfare, and a lack of support by Soviet citizens. | closed_qa |

Which player scored the Premier League winning goal for Manchester City vs. QPR in 2012? | Manchester City F.C. 3–2 Queens Park Rangers F.C was the final match of the 2011–12 Premier League season, contested at the Etihad Stadium between Manchester City and Queens Park Rangers on 13 May 2012. This match is considered the greatest Premier League moment in history.
City entered the match in first place on goal difference, being level on points with local rivals Manchester United, and needed to match United's result to win the league. Meanwhile, QPR entered the match one spot above the relegation zone, knowing that a draw would secure safety at the expense of Bolton Wanderers. City won the match in dramatic fashion, reversing a 2–1 deficit by scoring two goals in stoppage time, with the winner being scored by Sergio Agüero, to clinch their first league title since the 1967–68 season. The win began a period of dominance in English football for City, with the club winning five more Premier League titles over the subsequent 10 years.
The match, and more specifically the final goal of the match, has repeatedly been described as the greatest moment in Premier League history. The terms "93:20" and "Agueroooooo" have entered Manchester City folklore as a result, the former describing the exact second of the match at which point the final goal was scored, while the latter was commentator Martin Tyler's live response to the goal. | Sergio Aguero, in his first season for the club following a £30+ million move from Athletico Madrid ended the season as the club's leading goal scorer. Ten plus years later, he ended as the club's all-time leading goal scorer and holds the record for number of Premier League Hat-tricks.
In 2012, Manchester City and local rivals, Manchester United were leading a two horse race to win the Premier League. Manchester United had previously won the league title 19 times where as this would be Manchester City's first title in over 40 years.
It was Manchester City's to lose as they hosted relegation-bounded QPR at the Etihad Stadium and all was going to plan going into the first half following Zabaleta's goal to make it 1-0 (an unlikely goal scorer to say the least).
However, following a mistake from centre back, Joleon Lescott, a dramatic red card for former Manchester City player, Joey Barton and a surprise second goal from QPR to make it 2-1, Manchester City looked as though they'd let the title slip through their hands.
Manchester United had won their away game at Sunderland 1-0 so it was all down the blue half of Manchester's result.
Just after the 90th minute, they were in stoppage time which was extended due to the commotions with Joey Barton lashing out at Carlos Tevez and Sergio Aguero.
Striker, Edin Dzeko, scored a header from a David Silva cross to make it 2-2, but to many, this felt as too little, too late.
Late drama unfolded as Mario Balotelli registered his one and only assist in almost 4 years at the club as he laid it off to Aguero who scored the winning goal with the last kick of the game to make it 3-2.
Manchester City went on to win the league and QPR avoided relegation despite the loss due to results elsewhere. | closed_qa |
Given this mechanism that the Tesla Model Y car uses to heat the interior cabin, what are some pros and cons of this design? | The Model Y is Tesla's first car to use a heat pump instead of electric resistance for interior cabin heating. Some electric vehicles from other manufacturers, including the Nissan Leaf, Renault Zoe, BMW i3 EV, Jaguar I-Pace, Audi e-tron, and Kia Niro, had already implemented heat pumps. In cold weather, the Model Y heat pump can be up to 300% more efficient than other Tesla cars' use of electric resistance heating. Because of this, the Model Y should be more energy efficient than other Tesla cars in cold weather. Electric cars can lose 40% or more of their range in cold weather (at ambient temperatures below 20 °F (−7 °C)) when heating the interior cabin. | The heat pump in the Tesla Model Y runs the same heating operations as other cars but much more efficiently, significantly increasing driving range for the same battery size.

What's Jiang's theoretical contribution? | Jiang Zemin (17 August 1926 – 30 November 2022) was a Chinese politician who served as general secretary of the Chinese Communist Party (CCP) from 1989 to 2002, as chairman of the Central Military Commission from 1989 to 2004, and as president of China from 1993 to 2003. Jiang was paramount leader of China from 1989 to 2002. He was the core leader of the third generation of Chinese leadership, one of four core leaders alongside Mao Zedong, Deng Xiaoping and Xi Jinping.
Born in Yangzhou, Jiangsu, Jiang joined the CCP while he was in college. After the establishment of the People's Republic of China in 1949, he received training at the Stalin Automobile Works in Moscow in the 1950s, later returning to Shanghai in 1962 to serve in various institutes, later being sent between 1970-1972 to Romania as part of an expert team to establish machinery manufacturing plants in the country. After 1979, he was appointed as the vice chair of two commissions by vice premier Gu Mu to oversee the newly-established special economic zones (SEZs). He became the vice minister of the newly-established Ministry of Electronics Industry and a member of the CCP Central Committee in 1982.
Jiang was appointed as the mayor of Shanghai in 1985, later being promoted to its Communist Party secretary, as well as a member of the CCP Politburo, in 1987. Jiang came to power unexpectedly as a compromise candidate following the 1989 Tiananmen Square protests and massacre, when he replaced Zhao Ziyang as CCP general secretary after Zhao was ousted for his support for the student movement. As the involvement of the "Eight Elders" in Chinese politics steadily declined, Jiang consolidated his hold on power to become the "paramount leader" in the country during the 1990s. Urged by Deng Xiaoping's southern tour in 1992, Jiang officially introduced the term "socialist market economy" in his speech during the 14th CCP National Congress held later that year, which accelerated "opening up and reform".
Under Jiang's leadership, China experienced substantial economic growth with the continuation of market reforms. The returning of Hong Kong from the United Kingdom in 1997 and of Macau from Portugal in 1999, and entry into the World Trade Organisation in 2001, were landmark moments of his era. China also witnessed improved relations with the outside world, while the Communist Party maintained its tight control over the state. Jiang faced criticism over human rights abuses, including the crackdown on the Falun Gong movement. His contributions to party doctrine, known as the "Three Represents", were written into the CCP constitution in 2002. Jiang gradually vacated his official leadership titles from 2002 to 2005, being succeeded in these roles by Hu Jintao, although he and his political faction continued to influence affairs until much later. On 30 November 2022, Jiang died from leukemia and multiple organ failure in Shanghai. | The Three Represents | closed_qa |
Given the following paragraph on gene regulation, what are operons and where do they occur? | The regulation of gene expression by environmental factors and during different stages of development can occur at each step of the process such as transcription, RNA splicing, translation, and post-translational modification of a protein. Gene expression can be influenced by positive or negative regulation, depending on which of the two types of regulatory proteins called transcription factors bind to the DNA sequence close to or at a promoter. A cluster of genes that share the same promoter is called an operon, found mainly in prokaryotes and some lower eukaryotes (e.g., Caenorhabditis elegans). In positive regulation of gene expression, the activator is the transcription factor that stimulates transcription when it binds to the sequence near or at the promoter. Negative regulation occurs when another transcription factor called a repressor binds to a DNA sequence called an operator, which is part of an operon, to prevent transcription. Repressors can be inhibited by compounds called inducers (e.g., allolactose), thereby allowing transcription to occur. Specific genes that can be activated by inducers are called inducible genes, in contrast to constitutive genes that are almost constantly active. In contrast to both, structural genes encode proteins that are not involved in gene regulation. In addition to regulatory events involving the promoter, gene expression can also be regulated by epigenetic changes to chromatin, which is a complex of DNA and protein found in eukaryotic cells. | Operons are clusters of genes that share the same promoter.

What are the signs and symptoms of Sensory processing disorder? | Sensory integration difficulties or sensory processing disorder (SPD) are characterized by persistent challenges with neurological processing of sensory stimuli that interfere with a person's ability to participate in everyday life. Such challenges can appear in one or several sensory systems of the somatosensory system, vestibular system, proprioceptive system, interoceptive system, auditory system, visual system, olfactory system, and gustatory system.
While many people can present one or two symptoms, sensory processing disorder has to have a clear functional impact on the person's life:
Signs of over-responsivity, including, for example, dislike of textures such as those found in fabrics, foods, grooming products or other materials found in daily living, to which most people would not react, and serious discomfort, sickness or threat induced by normal sounds, lights, ambient temperature, movements, smells, tastes, or even inner sensations such as heartbeat.Signs of under-responsivity, including sluggishness and lack of responsiveness.
Sensory cravings, including, for example, fidgeting, impulsiveness, and/or seeking or making loud, disturbing noises; and sensorimotor-based problems, including slow and uncoordinated movements or poor handwriting.
Sensory discrimination problems, which might manifest themselves in behaviors such as things constantly dropped.
Symptoms may vary according to the disorder's type and subtype present.
Sensory integration and processing difficulties can be a feature of a number of disorders, including anxiety problems, attention deficit hyperactivity disorder (ADHD),food intolerances, behavioural disorders, and particularly, autism spectrum disorders. This pattern of comorbidities poses a significant challenge to those who claim that SPD is an identifiably specific disorder, rather than simply a term given to a set of symptoms common to other disorders.
Two studies have provided preliminary evidence suggesting that there may be measurable neurological differences between children diagnosed with SPD and control children classified as neurotypical or children diagnosed with autism. Despite this evidence, that SPD researchers have yet to agree on a proven, standardized diagnostic tool undermines researchers' ability to define the boundaries of the disorder and makes correlational studies, like those on structural brain abnormalities, less convincing. | While many people with Sensory processing disorder can present one or two symptoms, it has to have a clear functional impact on the person's life:

Based on the reference text about Bitcoin, how many countries have banned Bitcoin? | Bitcoin (abbreviation: BTC or XBT; sign: ₿) is a protocol which implements a highly available, public, permanent, and decentralized ledger. In order to add to the ledger, a user must prove they control an entry in the ledger. The protocol specifies that the entry indicates an amount of a token, bitcoin with a minuscule b. The user can update the ledger, assigning some of their bitcoin to another entry in the ledger. Because the token has characteristics of money, it can be thought of as a digital currency.
Bitcoin transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. The cryptocurrency was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto. The currency began use in 2009, when its implementation was released as open-source software.: ch. 1 The word "bitcoin" was defined in a white paper published on October 31, 2008.

Given this paragraph about magnesium, what is the atomic number of magnesium? | Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. | The atomic number of magnesium is 12. | closed_qa |
When was Campbell, CA founded? | n 1878, Campbell sold his land for $5 an acre to a railroad company. By 1887, the first subdivision was recorded west of the railroad, from Campbell Avenue to the spot where the Water Tower Plaza now stands. He and his wife Mary (née Rucker) Campbell (1834–1913) founded the city which was first known as Campbell's Place, but would later become the town of Campbell.
In 1888, the Campbell School District was formed.
The area became the center for shipping fruit grown in the surrounding area, and within a short time, the drying grounds and canneries made Campbell an important rail center. By 1892, the Campbell Fruit Growers' Union became a well-known cooperative with its 17-acre (69,000 m2) drying yard. J.C. Ainsley Packing Company, Hyde Cannery, and Payne Cannery were the main fruit packing companies.
In 1895, The Bank of Campbell was founded and the first newspaper, the Campbell Weekly Visitor, began publication.

In Africa, were cattle domesticated before or after agriculture? | The domestication of cattle in Africa preceded agriculture and seems to have existed alongside hunter-gatherer cultures. It is speculated that by 6000 BCE, cattle were domesticated in North Africa. In the Sahara-Nile complex, people domesticated many animals, including the donkey and a small screw-horned goat which was common from Algeria to Nubia.
Between 10,000 and 9,000 BCE, pottery was independently invented in the region of Mali in the savannah of West Africa.
In the steppes and savannahs of the Sahara and Sahel in Northern West Africa, people possibly ancestral to modern Nilo-Saharan and Mandé cultures started to collect wild millet, around 8000 to 6000 BCE. Later, gourds, watermelons, castor beans, and cotton were also collected.

What is one of the first recorded mentions of the sauna in Finnish literature? | "The sauna in Finland is an old phenomenon and its roots are difficult to trace, but its earliest versions are believed to be from 7000 BC.[citation needed] Bath houses were recorded in Europe during the same time period, but Finnish bathing habits were poorly documented for most of history. One of the first written mentions of what is believed to be the sauna customs of the forefathers of the Finns was written by Nestor the Chronicler in 1112. He told of ""hot wooden saunas in which naked bathers beat themselves with branches and finally pour cold water over themselves"".
During the Reformation in Scandinavia the popularity of saunas expanded to other countries because the European bath houses were being destroyed.
One reason the sauna culture has always flourished in Finland has been because of the versatility of the sauna. When people were moving, the first thing they did was to build a sauna. Finns have used the sauna to live in, eat, address matters of hygiene, and, most importantly, give birth in an almost sterile environment. Unlike many other, more densely populated places in Europe, the availability of wood needed to build and warm the sauna has never been an issue. Another reason for its popularity is that in such a cold climate, the sauna allows people warmth for at least a short period of time.

Given a reference text about Francoist Spain, when did Franco rule Spain and when did he die? | Francoist Spain (Spanish: España franquista), or the Francoist dictatorship (dictadura franquista), was the period of Spanish history between 1939 and 1975, when Francisco Franco ruled Spain after the Spanish Civil War with the title Caudillo. After his death in 1975, Spain transitioned into a democracy. During this time period, Spain was officially known as the Spanish State (Estado Español).
The nature of the regime evolved and changed during its existence. Months after the start of the Spanish Civil War in July 1936, Franco emerged as the dominant rebel military leader and was proclaimed head of state on 1 October 1936, ruling a dictatorship over the territory controlled by the Nationalist faction. The 1937 Unification Decree, which merged all parties supporting the rebel side, led to Nationalist Spain becoming a single-party regime under the FET y de las JONS. The end of the war in 1939 brought the extension of the Franco rule to the whole country and the exile of Republican institutions. The Francoist dictatorship originally took a form described as "fascistized dictatorship", or "semi-fascist regime", showing clear influence of fascism in fields such as labor relations, the autarkic economic policy, aesthetics, and the single-party system. As time went on, the regime opened up and became closer to developmental dictatorships, although it always preserved residual fascist elements. | Francisco Franco ruled Spain from 1935 until he died in 1975. | closed_qa |

Given the reference text about Super Bowl LV, please answer the following questions:
1. Who performed at the halftime show?
2. Which team won and what was the final score?
3. Who was the MVP?
4. Where was the game played? | Super Bowl LV was an American football game played to determine the champion of the National Football League (NFL) for the 2020 season. The National Football Conference (NFC) champion Tampa Bay Buccaneers defeated the defending American Football Conference (AFC) and Super Bowl champion Kansas City Chiefs, 31–9. The game was played on February 7, 2021, at Raymond James Stadium in Tampa, Florida, the home stadium of the Buccaneers, marking the first time a team played a Super Bowl in its home stadium. Due to COVID-19 protocols limiting the stadium's seating capacity to 25,000 fans, it was the least-attended Super Bowl.
The Buccaneers' victory was their second and made them one of two teams, along with the Baltimore Ravens, to be undefeated in multiple Super Bowls. They finished the regular season with an 11–5 record and a wild card berth to advance to their second Super Bowl appearance through the guidance of several new acquisitions, most notably 21-year veteran quarterback Tom Brady in his first season away from the New England Patriots. The Chiefs, aided by their top-ranked offense, finished the regular season with a league-best 14–2 record to advance to their fourth Super Bowl appearance and were the defending Super Bowl LIV champions, seeking to become the first repeat champions since the Patriots in 2004.
For the first time under quarterback Patrick Mahomes, the Chiefs failed to score a touchdown and lost by double-digits, making them the third Super Bowl team to not score a touchdown. They also committed 11 penalties for 120 yards, including a record eight penalties for 95 yards in the first half, most of which were called against the defense. The Buccaneers capitalized on these struggles to take a commanding 21–6 lead at halftime and dominated the remainder of the game. Brady, who also extended his player records for Super Bowl appearances to 10 and wins to seven, was named Super Bowl MVP for a record fifth time and was the first to receive the award with multiple franchises. He became the oldest player to receive the honor and win a Super Bowl as the starting quarterback at age 43, breaking additional personal records, while Bruce Arians was the oldest head coach to win the Super Bowl at 68.
The game was televised nationally by CBS. Country music singer Eric Church and R&B singer Jazmine Sullivan performed the national anthem, while the halftime show was headlined by Canadian singer The Weeknd. On television, Super Bowl LV was seen by 91.63 million viewers, the lowest ratings for the game since 2006. Combined with viewership on other platforms, viewership was down by 5% overall in comparison to Super Bowl LIV, but with a 69% increase in average streaming viewership. | Given the provided reference text, the answers to the questions are as follows:

Given the reference text about the history of the Olympic marathon distance, tell me what was the distance of the Olympic marathon during the 1924 Olympics in Paris in kilometers? | The International Olympic Committee agreed in 1907 that the distance for the 1908 London Olympic marathon would be about 25 miles or 40 kilometers. The organizers decided on a course of 26 miles from the start at Windsor Castle to the royal entrance to the White City Stadium, followed by a lap (586 yards 2 feet; 536 m) of the track, finishing in front of the Royal Box. The course was later altered to use a different entrance to the stadium, followed by a partial lap of 385 yards to the same finish.
The modern 42.195 km (26.219 mi) standard distance for the marathon was set by the International Amateur Athletic Federation (IAAF) in May 1921 directly from the length used at the 1908 Summer Olympics in London. | The distance of the Olympic marathon in 1924 would have been 42.195 kilometers, since this is the standard distance set by the IAAF in 1921. | closed_qa |
Luka Modrić (Croatian pronunciation: [lûːka mǒːdritɕ]; born 9 September 1985) is a Croatian professional footballer who plays as a midfielder for La Liga club Real Madrid and captains the Croatia national team. He plays mainly as a central midfielder, but can also play as an attacking midfielder or as a defensive midfielder. He is widely regarded as one of the greatest midfielders of all time, and as the greatest ever Croatian footballer.
Born in Zadar, Modrić's childhood coincided with the Croatian War of Independence which displaced his family. In 2002, he was signed by Dinamo Zagreb at age 16, after showing promise with his hometown club NK Zadar's youth team. He continued his development in Zagreb, before spells on loan to Zrinjski Mostar and Inter Zaprešić. He made his debut for Dinamo in 2005 and won three consecutive league titles and domestic cups, being named the Prva HNL Player of the Year in 2007. In 2008, he moved to Premier League club Tottenham Hotspur for a club-record transfer fee of £16.5 million, where he led Spurs to their first UEFA Champions League appearance in almost 50 years, reaching the quarter-finals of the 2010–11 tournament.
In the summer of 2012, Modrić joined Real Madrid for a £30 million transfer fee. There he became a key contributor and helped the team win La Décima and was selected for the 2013–14 Champions League squad of the season. After Zinedine Zidane took over Madrid, Modrić was critical to three consecutive Champions League titles from 2015–16 to 2017–18, each time being voted into the squad of the season. He has won twenty-two major trophies at Real Madrid, including five UEFA Champions League titles, three La Liga titles, one Copa del Rey, four Supercopa de España titles, four UEFA Super Cup titles and five FIFA Club World Cup titles. He won the La Liga Award for "Best Midfielder" in 2016 for the second time, and the UEFA Club Football Award for "Best Midfielder" in 2017 and 2018. In 2015, he became the first Croatian player to be included in the FIFA FIFPRO World 11, in which he was regularly included until 2019 and then again in 2022, as well in the UEFA Team of the Year between 2016 and 2018. In 2018, Modrić became the first Croatian player to win the UEFA Men's Player of the Year Award, and by winning The Best FIFA Men's Player and Ballon d'Or awards, he became the first player other than Lionel Messi or Cristiano Ronaldo to claim the awards in more than a decade. In 2019, he was awarded the Golden Foot award for career results and personality.
Modrić made his international debut for Croatia against Argentina in March 2006, and scored his first international goal in a friendly match against Italy. Modrić has anchored Croatia's "second Golden Generation", participating in every major tournament Croatia has qualified for, including the UEFA Euro 2008, 2012, 2016, and 2020, as well as the 2006, 2014, 2018, and 2022 FIFA World Cup. At the Euro 2008, he was selected for the Team of the Tournament, becoming only the second Croatian to ever achieve this honour. Following group stage eliminations in his first two World Cups, Modrić led Croatia to the 2018 World Cup Final, winning the Golden Ball in process. At the following tournament, he led the team to a third-place finish, winning the Bronze Ball in process. In March 2021, he went on to become the country's most capped player in history. Furthermore, he has been named Croatian Footballer of the Year a record eleven times between 2007 and 2022. | Who is Luka Modric? | Luka Modric is a Croatian professional football (soccer) player.

From this paragraph, tell me when Mary died and when did Elizabeth had Mary, Queen of Scots imprisoned. Also, who supported plots to have Elizabeth overthrown? | Mary's death in 1558 led to her half-sister Elizabeth taking the throne. Unlike Mary, Elizabeth was firmly in the reformist camp and quickly reimplemented many of Edward's reforms. Philip, no longer co-monarch, deemed Elizabeth a heretic and illegitimate ruler of England. In the eyes of the Catholic Church, Henry had never officially divorced Catherine, making Elizabeth illegitimate. It is alleged that Philip supported plots to have Elizabeth overthrown in favour of her Catholic cousin and heir presumptive, Mary, Queen of Scots. These plans were thwarted when Elizabeth had Mary imprisoned in 1567. Mary was forced to abdicate the crown of Scotland in favour of her son James VI. The first documented suggestion of what was called the Enterprise of England was in the summer of 1583 when, flushed with pride of his victory in the Azores, Álvaro de Bazán, Marquis of Santa Cruz addressed the suggestion to Philip II of taking advantage of it to attack England. | Mary (Bloody Mary) died in 1558 and Elizabeth had Mary (Queen of Scots) imprisoned in 1567.

Given this article about Operation Aurora, which companies were targeted in the attacks? | Operation Aurora was a series of cyber attacks conducted by advanced persistent threats such as the Elderwood Group based in Beijing, China, with ties to the People's Liberation Army. First publicly disclosed by Google on January 12, 2010, in a blog post, the attacks began in mid-2009 and continued through December 2009.
The attack was aimed at dozens of other organizations, of which Adobe Systems, Akamai Technologies, Juniper Networks, and Rackspace have publicly confirmed that they were targeted. According to media reports, Yahoo, Symantec, Northrop Grumman, Morgan Stanley, and Dow Chemical were also among the targets.
As a result of the attack, Google stated in its blog that it plans to operate a completely uncensored version of its search engine in China "within the law, if at all," and acknowledged that if this is not possible, it may leave China and close its Chinese offices. Official Chinese sources claimed this was part of a strategy developed by the U.S. government.
The attack was named "Operation Aurora" by Dmitri Alperovitch, Vice President of Threat Research at cybersecurity company McAfee. Research by McAfee Labs discovered that "Aurora" was part of the file path on the attacker's machine that was included in two of the malware binaries McAfee said were associated with the attack. "We believe the name was the internal name the attacker(s) gave to this operation," McAfee Chief Technology Officer George Kurtz said in a blog post.
According to McAfee, the primary goal of the attack was to gain access to and potentially modify source code repositories at these high-tech, security, and defense contractor companies. "[The SCMs] were wide open," says Alperovitch. "No one ever thought about securing them, yet these were the crown jewels of most of these companies in many ways—much more valuable than any financial or personally identifiable data that they may have and spend so much time and effort protecting."
History
Flowers left outside Google China's headquarters after its announcement it might leave the country
On January 12, 2010, Google revealed on its blog that it had been the victim of a cyber attack. The company said the attack occurred in mid-December and originated from China. Google stated that over 20 other companies had been attacked; other sources have since cited that more than 34 organizations were targeted. As a result of the attack, Google said it was reviewing its business in China. On the same day, United States Secretary of State Hillary Clinton issued a brief statement condemning the attacks and requesting a response from China.
On January 13, 2010, the news agency All Headline News reported that the United States Congress plans to investigate Google's allegations that the Chinese government used the company's service to spy on human rights activists.
In Beijing, visitors left flowers outside of Google's office. However, these were later removed, with a Chinese security guard stating that this was an "illegal flower tribute". The Chinese government has yet to issue a formal response, although an anonymous official stated that China was seeking more information on Google's intentions.
Attackers involved
Further information: Cyberwarfare by China
Technical evidence including IP addresses, domain names, malware signatures, and other factors, show Elderwood was behind the Operation Aurora attack. The "Elderwood" group was named by Symantec (after a source-code variable used by the attackers), and is referred to as the "Beijing Group" by Dell Secureworks. The group obtained some of Google's source code, as well as access to information about Chinese activists. Elderwood also targeted numerous other companies in the shipping, aeronautics, arms, energy, manufacturing, engineering, electronics, financial, and software sectors.
The "APT" designation for the Chinese threat actors responsible for attacking Google is APT17.
Elderwood specializes in attacking and infiltrating second-tier defense industry suppliers that make electronic or mechanical components for top defense companies. Those firms then become a cyber "stepping stone" to gain access to top-tier defense contractors. One attack procedure used by Elderwood is to infect legitimate websites frequented by employees of the target company – a so-called "water hole" attack, just as lions stake out a watering hole for their prey. Elderwood infects these less-secure sites with malware that downloads to a computer that clicks on the site. After that, the group searches inside the network to which the infected computer is connected, finding and then downloading executives' e-mails and critical documents on company plans, decisions, acquisitions, and product designs.
Attack analysis
In its blog posting, Google stated that some of its intellectual property had been stolen. It suggested that the attackers were interested in accessing Gmail accounts of Chinese dissidents. According to the Financial Times, two accounts used by Ai Weiwei had been attacked, their contents read and copied; his bank accounts were investigated by state security agents who claimed he was under investigation for "unspecified suspected crimes". However, the attackers were only able to view details on two accounts and those details were limited to things such as the subject line and the accounts' creation date.
Security experts immediately noted the sophistication of the attack. Two days after the attack became public, McAfee reported that the attackers had exploited purported zero-day vulnerabilities (unfixed and previously unknown to the target system developers) in Internet Explorer and dubbed the attack "Operation Aurora". A week after the report by McAfee, Microsoft issued a fix for the issue, and admitted that they had known about the security hole used since September. Additional vulnerabilities were found in Perforce, the source code revision software used by Google to manage their source code.
VeriSign's iDefense Labs claimed that the attacks were perpetrated by "agents of the Chinese state or proxies thereof".
According to a diplomatic cable from the U.S. Embassy in Beijing, a Chinese source reported that the Chinese Politburo directed the intrusion into Google's computer systems. The cable suggested that the attack was part of a coordinated campaign executed by "government operatives, public security experts and Internet outlaws recruited by the Chinese government." The report suggested that it was part of an ongoing campaign in which attackers have "broken into American government computers and those of Western allies, the Dalai Lama and American businesses since 2002." According to The Guardian's reporting on the leak, the attacks were "orchestrated by a senior member of the Politburo who typed his own name into the global version of the search engine and found articles criticising him personally."
Once a victim's system was compromised, a backdoor connection that masqueraded as an SSL connection made connections to command and control servers running in Illinois, Texas, and Taiwan, including machines that were running under stolen Rackspace customer accounts. The victim's machine then began exploring the protected corporate intranet that it was a part of, searching for other vulnerable systems as well as sources of intellectual property, specifically the contents of source code repositories.
The attacks were thought to have definitively ended on Jan 4 when the command and control servers were taken down, although it is not known at this point whether or not the attackers intentionally shut them down. However, the attacks were still occurring as of February 2010.
Response and aftermath
The German, Australian, and French governments publicly issued warnings to users of Internet Explorer after the attack, advising them to use alternative browsers at least until a fix for the security hole was made. The German, Australian, and French governments considered all versions of Internet Explorer vulnerable or potentially vulnerable.
In an advisory on January 14, 2010, Microsoft said that attackers targeting Google and other U.S. companies used software that exploits a hole in Internet Explorer. The vulnerability affects Internet Explorer versions 6, 7, and 8 on Windows 7, Vista, Windows XP, Server 2003, Server 2008 R2, as well as IE 6 Service Pack 1 on Windows 2000 Service Pack 4.
The Internet Explorer exploit code used in the attack has been released into the public domain, and has been incorporated into the Metasploit Framework penetration testing tool. A copy of the exploit was uploaded to Wepawet, a service for detecting and analyzing web-based malware operated by the computer security group at the University of California, Santa Barbara. "The public release of the exploit code increases the possibility of widespread attacks using the Internet Explorer vulnerability," said George Kurtz, CTO of McAfee, of the attack. "The now public computer code may help cybercriminals craft attacks that use the vulnerability to compromise Windows systems."
Security company Websense said it identified "limited public use" of the unpatched IE vulnerability in drive-by attacks against users who strayed onto malicious Web sites. According to Websense, the attack code it spotted is the same as the exploit that went public last week.[clarification needed] "Internet Explorer users currently face a real and present danger due to the public disclosure of the vulnerability and release of attack code, increasing the possibility of widespread attacks," said George Kurtz, chief technology officer of McAfee, in a blog update. Confirming this speculation, Websense Security Labs identified additional sites using the exploit on January 19. According to reports from Ahnlab, the second URL was spread through the Instant Messenger network Misslee Messenger, a popular IM client in South Korea.
Researchers have created attack code that exploits the vulnerability in Internet Explorer 7 (IE7) and IE8—even when Microsoft's recommended defensive measure (Data Execution Prevention (DEP)) is turned on.[dubious – discuss] According to Dino Dai Zovi, a security vulnerability researcher, "even the newest IE8 isn't safe from attack if it's running on Windows XP Service Pack 2 (SP2) or earlier, or on Windows Vista RTM (release to manufacturing), the version Microsoft shipped in January 2007."
Microsoft admitted that the security hole used had been known to them since September. Work on an update was prioritized and on Thursday, January 21, 2010, Microsoft released a security patch aiming to counter this weakness, the published exploits based on it and a number of other privately reported vulnerabilities. They did not state if any of the latter had been used or published by exploiters or whether these had any particular relation to the Aurora operation, but the entire cumulative update was termed critical for most versions of Windows, including Windows 7.
Security researchers continued to investigate the attacks. HBGary, a security firm, released a report in which they claimed to have found some significant markers that might help identify the code developer. The firm also said that the code was Chinese language based but could not be specifically tied to any government entity.
On February 19, 2010, a security expert investigating the cyber-attack on Google, has claimed that the people behind the attack were also responsible for the cyber-attacks made on several Fortune 100 companies in the past one and a half years. They have also tracked the attack back to its point of origin, which seems to be two Chinese schools, Shanghai Jiao Tong University and Lanxiang Vocational School. As highlighted by The New York Times, both of these schools have ties with the Chinese search engine Baidu, a rival of Google China. Both Lanxiang Vocational and Jiaotong University have denied the allegation.
In March 2010, Symantec, which was helping investigate the attack for Google, identified Shaoxing as the source of 21.3% of all (12 billion) malicious emails sent throughout the world.
