context: Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number.[2] However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was developed in 1995,[3] and standardized in December 1998.[4] In July 2017, a final definition of the protocol was published.[5] IPv6 deployment has been ongoing since the mid-2000s. answers: 1995	When was the IP address concept first developed?
context: The Red Delicious is a clone of apple cultigen, now comprising more than 50 cultivars, first recognized in Madison County, Iowa, in 1880. According to the US Apple Association website, it is one of the fifteen most popular apple cultivars in the United States.[1] answers: 1880	When was the red delicious apple introduced?
context: The water rail (Rallus aquaticus) is a bird of the rail family which breeds in well-vegetated wetlands across Europe, Asia and North Africa. Northern and eastern populations are migratory, but this species is a permanent resident in the warmer parts of its breeding range. The adult is 23–28cm (9–11in) long, and, like other rails, has a body that is flattened laterally, allowing it easier passage through the reed beds it inhabits. It has mainly brown upperparts and blue-grey underparts, black barring on the flanks, long toes, a short tail and a long reddish bill. Immature birds are generally similar in appearance to the adults, but the blue-grey in the plumage is replaced by buff. The downy chicks are black, as with all rails. The former subspecies R.indicus, has distinctive markings and a call that is very different from the pig-like squeal of the western races, and is now usually split as a separate species, the brown-cheeked rail. answers: The adult is 23–28cm (9–11in) long	How large is the water rail?
context: Cyrus II of Persia (Old Persian: 𐎤𐎢𐎽𐎢𐏁 Kūruš;[4] New Persian: کوروش Kuruš; Hebrew: כורש, Modern:Kōréš, Tiberian:Kōréš; c.600–530BC),[5] commonly known as Cyrus the Great[6] and also called Cyrus the Elder by the Greeks, was the founder of the Achaemenid Empire, the first Persian Empire.[7] Under his rule, the empire embraced all the previous civilized states of the ancient Near East,[7] expanded vastly and eventually conquered most of Western Asia and much of Central Asia. From the Mediterranean Sea and Hellespont in the west to the Indus River in the east, Cyrus the Great created the largest empire the world had yet seen.[8] Under his successors, the empire eventually stretched at its maximum extent from parts of the Balkans (Bulgaria-Paeonia and Thrace-Macedonia) and Eastern Europe proper in the west, to the Indus Valley in the east. His regal titles in full were The Great King, King of Persia, King of Anshan, King of Media, King of Babylon, King of Sumer and Akkad, and King of the Four Corners of the World. The Nabonidus Chronicle notes the change in his title from simply "King of Anshan", a city, to "King of Persia". Assyriologist François Vallat wrote that "When Astyages marched against Cyrus, Cyrus is called ‘King of Anshan’, but when Cyrus crosses the Tigris on his way to Lydia, he is ‘King of Persia’. The coup therefore took place between these two events."[9] answers: –530BC),[5]	When did Cyrus the Great live?
context: Michelangelo's father sent him to study grammar with the Renaissance humanist Francesco da Urbino in Florence as a young boy.[1] The young artist, however, showed no interest in his schooling, preferring to copy paintings from churches and seek the company of painters.[1] At thirteen, Michelangelo was apprenticed to the painter Domenico Ghirlandaio.[2] When Michelangelo was only fourteen, his father persuaded Ghirlandaio to pay his apprentice as an artist, which was highly unusual at the time.[3] When in 1489 Lorenzo de' Medici ("Lorenzo il Magnifico), de facto ruler of Florence, asked Ghirlandaio for his two best pupils, Ghirlandaio sent Michelangelo and Francesco Granacci.[3] Lorenzo had taken notice of Michelangelo’s unusual talent and, wishing to encourage him, proposed for Michelangelo to move into the palace and live there as his son to be educated along with the Medici children. Lorenzo even offered Michelangelo’s father Lodovico a respectable position in the palace. Michelangelo was thrown into the midst of the Medici circle where he was involved with poetry, science, philosophy, and art. answers: Ghirlandaio	Who was Michelangelo's teacher?
context: It evolved from *Admiralty Navy War Council, (1909–1912) which in turn became the Admiralty War Staff, (1912–1917) before finally becoming the Admiralty Naval Staff in 1917. It was the former senior command, operational planning, policy and strategy department within the British Admiralty. It was established in 1917 and existed until 1964 when the department of the Admiralty was abolished, and the staff departments function continued within the Navy Department of the Ministry of Defence until 1971 when its functions became part of the new Naval Staff, Navy Department of the Ministry of Defence.[9] answers: 1917	When was the British Admiralty founded?
context: Ductility can be quantified by the fracture strain ε f {\displaystyle \varepsilon _{f}} , which is the engineering strain at which a test specimen fractures during a uniaxial tensile test. Another commonly used measure is the reduction of area at fracture q {\displaystyle q} .[5] The ductility of steel varies depending on the alloying constituents. Increasing the levels of carbon decreases ductility. Many plastics and amorphous solids, such as Play-Doh, are also malleable. The most ductile metal is platinum and the most malleable metal is gold.[6][7] answers: gold	What's the most malleable metal?
context: Fessenden is best known for his pioneering work developing radio technology, including the foundations of amplitude modulation (AM) radio. His achievements included the first transmission of speech by radio (1900), and the first two-way radiotelegraphic communication across the Atlantic Ocean (1906). In 1932 he reported that, in late 1906, he also made the first radio broadcast of entertainment and music, although a lack of verifiable details has led to some doubts about this claim. answers: radio technology	What was Reginald Aubrey Fessenden's first patented invention?
