Matter is made of very small particles called atoms. Atoms can be linked together by chemical bonds. When two or more atoms link together, they form a molecule.
In a chemical change, the chemical bonds in the molecules break. The atoms then link together to form new molecules. The types of molecules in matter before and after a chemical change are always different.
Burning a piece of paper is a chemical change. As paper burns, paper molecules react with oxygen molecules in the air. This reaction breaks the chemical bonds in the molecules. The atoms then relink and form different molecules. For example, carbon dioxide molecules are created when paper burns.
In a physical change, chemical bonds do not break. The types of molecules in matter before and after a physical change are always the same.
A change of state is a type of physical change. For example, water vaporizing is a physical change. Liquid water and water vapor are made of the same type of matter: water.

Question:
Complete the sentence.
An igneous rock becoming a metamorphic rock is a ().

0. physical change
1. chemical change

[Assistant]
An igneous rock becoming a metamorphic rock is a chemical change. Over millions of years, heat and pressure can break the chemical bonds in the molecules of the igneous rock.
When this happens, a new rock with different molecules is formed. The metamorphic rock is made up of a different type of matter than the igneous rock.

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
Volume is a measurement of how much space something takes up.
There are many different units of volume. When you are using metric units, volume may be written in units of milliliters or liters.
There are 1,000 milliliters in 1 liter. So, 1 milliliter is much less than 1 liter.
A raindrop has a volume of about 20 milliliters, while a large soda bottle has a volume of 2 liters. The flask shown here measures volumes up to 500 milliliters.

Question:
What is the volume of a kiddie pool?

0. 1,070 liters

Words change in meaning when speakers begin using them in new ways. For example, the word peruse once only meant to examine in detail, but it's now also commonly used to mean to look through in a casual manner.
When a word changes in meaning, its correct usage is often debated. Although a newer sense of the word may be more commonly used, many people consider a word's traditional definition to be the correct usage. Being able to distinguish the different uses of a word can help you use it appropriately for different audiences.
Britney perused her notes, carefully preparing for her exam.
The traditional usage above is considered more standard.
David perused the magazine, absentmindedly flipping through the pages.
The nontraditional usage above is now commonly used, but traditional style guides generally advise against it.

Question:
Which text uses the word peruse in its traditional sense?

Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways.
Inherited traits are passed down from biological parents to their offspring through genes. Genes are pieces of hereditary material that contain the instructions that affect inherited traits. Offspring receive their genes, and therefore gain their inherited traits, from their biological parents. Inherited traits do not need to be learned.
Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment. Parents do not pass acquired traits down to their offspring.

Question:
What information supports the conclusion that Zeke inherited this trait?

0. Zeke wears glasses and so do his sisters.
1. Zeke's friend also has hazel eyes.
2. Zeke's biological father wears contacts in his hazel eyes.

A chemical change occurs when new substances are formed from existing substances. This process is called a chemical reaction.
In a chemical reaction, one or more substances change into one or more different substances. During the reaction, the atoms of the original substances are rearranged to form other substances.
The original substances in a chemical reaction are called reactants. These substances react, or go through a chemical change.
The substances that are formed in a chemical reaction are called products. These substances are produced by the chemical reaction.
So, in a chemical reaction, reactants go through a chemical change to form products.

Question:
Complete the sentence.
In this chemical reaction, oxygen is a ().

0. reactant
1. product

[Assistant]
Read the underlined text carefully. Look for information about what happens to oxygen in this chemical reaction.
The Space Shuttle program sent astronauts on 135 missions using a fleet of five shuttles between 1981 and 2011. The engines of each shuttle, like other modern rocket engines, used liquid hydrogen as fuel. When liquid hydrogen combines with liquid oxygen, an enormous amount of energy is released, along with water vapor. The shuttles used this energy to launch into space.
The underlined text tells you that when hydrogen and oxygen combine, water is formed. When hydrogen and oxygen react, or go through a chemical change, their atoms are rearranged to form water. Because oxygen reacts in this chemical reaction, oxygen is a reactant.
Therefore my final answer is: 0

Vague pronoun references can be corrected in one of two ways:
1. Replace the pronoun with its correct antecedent:
When Lisa and Kim finally landed, Lisa breathed a sigh of relief.
2. Rewrite the sentence:
Lisa breathed a sigh of relief when she and Kim finally landed.
A vague pronoun reference also occurs when they, them, their, theirs, it, or its is used without its antecedent.

A paradox is a statement that might at first appear to be contradictory, but that may in fact contain some truth.
Always expect the unexpected.

Question:
Which figure of speech is used in this text?
My sister always wears at least five pieces of jewelry, but I prefer to follow the guideline "Less is more."

0. paradox
1. euphemism

[Assistant]
The text uses a paradox, a statement that might at first appear to be contradictory, but that may in fact contain some truth.
Less is more at first appears to be contradictory, since less and more are opposites. However, it contains some truth: by removing something or scaling back, you can sometimes achieve a more complete or pleasing outcome.
Therefore my final answer is: 0

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
Imagine being told that the bus leaves in 7. You might be thinking, 7 what? Does the bus leave in 7 minutes? 7 seconds?
The number 7 on its own does not give you much information about when the bus is leaving. That is because the units are missing.
Time is usually measured in units of seconds, minutes, or hours. It takes about 1 second to sneeze and 1 minute to get dressed in the morning. It takes about 1 hour to bake a pie in the oven.
There are 60 seconds in 1 minute. So, 1 second is much less than 1 minute.
There are 60 minutes in 1 hour. So, 1 minute is much less than 1 hour.

Question:
How long does it take to do ten jumping jacks?

0. 28 seconds
1. 28 hours

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
Mass is a measurement of how much matter something contains.
There are many different units of mass. When you are using customary units, mass may be written with units of ounces, pounds, or tons.
There are 16 ounces in 1 pound and 2,000 pounds in 1 ton.
So, 1 ounce is less than 1 pound and much less than 1 ton.
A slice of bread has a mass of about 1 ounce, while a can of beans has a mass of about 1 pound. A small car has a mass of about 1 ton.

Question:
What is the mass of a bicycle?

0. 24 tons
1. 24 pounds
2. 24 ounces

[Assistant]
The best estimate for the mass of a bicycle is 24 pounds.
24 ounces is too light and 24 tons is too heavy.

A sentence is a group of words that expresses a complete thought.
The band I'm in has been rehearsing daily because we have a concert in two weeks.
A run-on sentence is formed when two sentences are run together, joined by just a comma or by no punctuation at all. If only a comma is used, the run-on is called a comma splice.
The band I'm in has been rehearsing daily, we have a concert in two weeks.
The band I'm in has been rehearsing daily we have a concert in two weeks.
There are several ways to fix a run-on sentence:
Use stronger punctuation, such as a period or a semicolon.
The band I'm in has been rehearsing daily. We have a concert in two weeks.
The band I'm in has been rehearsing daily; we have a concert in two weeks.
Use a comma and a coordinating conjunction to create a compound sentence. Coordinating conjunctions include and, but, or, and so.
The band I'm in has been rehearsing daily, and we have a concert in two weeks.
Use a subordinating conjunction or a relative pronoun to create a complex sentence. Subordinating conjunctions include after, although, as, because, before, if, since, unless, until, when, and while. Relative pronouns include that, which, who, whom, and whose.
The band I'm in has been rehearsing daily since we have a concert in two weeks.

Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways.
Inherited traits are passed down from biological parents to their offspring through genes. Genes are pieces of hereditary material that contain the instructions that affect inherited traits. Offspring receive their genes, and therefore gain their inherited traits, from their biological parents. Inherited traits do not need to be learned.
Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment. Parents do not pass acquired traits down to their offspring.

Question:
What information supports the conclusion that Lily inherited this trait?

0. Some people use a hair dryer to straighten their hair. But Lily and her brothers have naturally straight hair.
1. Both of Lily's biological parents have naturally black hair.
2. When she was younger, Lily wore ribbons in her naturally black hair.

Similes and metaphors are figures of speech that compare two things that are not actually alike.
A simile compares two things by saying that one is like the other. Similes often use the words like and as.
My sister runs like a cheetah.
The sister's running and a cheetah's running are compared using the word like.
A cheetah is known for running fast, so the simile means that the sister also runs fast.
The cat's fur was as dark as the night.
The cat's fur and the night are compared using the word as.
The night is dark, so the simile means that the cat's fur is also dark.
A metaphor compares two things by saying that one of them is the other. Unlike similes, metaphors don't use the word like or as.
The snow formed a blanket over the town.
The snow and a blanket are compared without the word like or as.
A blanket is a large piece of cloth that completely covers a bed. The metaphor makes the reader imagine that the snow becomes a blanket, covering the town completely.
Using similes and metaphors in your writing can help you create an interesting picture for the reader.

Question:
Does the sentence use a simile or a metaphor?
On that winter morning, Elizabeth's hands were as cold as ice.

A force is a push or a pull that acts on an object. Every force has a direction and a magnitude, or strength. If two forces act on an object in opposite directions, the forces are called opposing forces.
When opposing forces have the same magnitude, they are balanced. If all the forces on an object are balanced, there is no net force on the object.
When opposing forces have different magnitudes, the forces are unbalanced. If any forces on an object are unbalanced, there is a net force on the object.

Question:
Assume all other forces on Katy are balanced. Which statement describes the forces on Katy?

0. The forces are balanced, so there is no net force on Katy.
1. The forces are unbalanced, so there is a net force on Katy.

[Assistant]
To determine if there is a net force on Katy, look at the forces:
Earth's gravity is pulling Katy down with a force of 600 N.
The seat of the cart is pushing Katy up with a force of 1,200 N.
The forces are in opposite directions, and the forces have different magnitudes: 600 N and 1,200 N. This means that the forces are unbalanced, so there is a net force on Katy.
Therefore my final answer is: 1

All organisms have pieces of hereditary material called genes, which are passed from parents to offspring. Genes contain instructions for building the parts of an organism. An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have. Genes may have different alleles, or forms, that can cause different versions of a trait.
For example, flower color is a trait in pea plants. The gene for this trait has two possible alleles. Each allele is represented by an uppercase or lowercase letter. The allele F is for purple flowers, and the allele f is for white flowers. Each pea plant has two alleles for the flower color geneone allele inherited from each parent.
An organism's genotype for a gene is its combination of alleles for that gene. So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene.
An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles. A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait.
Some traits, like flower color in pea plants, are controlled by a single gene. Most plants and animals have a genotype made up of two alleles for these traits. These two alleles determine whether an organism is homozygous or heterozygous for the gene.
An organism with two identical alleles for a gene is homozygous for that gene. A pea plant with the genotype FF or ff is homozygous for the flower color gene.
An organism with two different alleles for a gene is heterozygous for that gene. A pea plant with the genotype Ff is heterozygous for the flower color gene.
The types of alleles in an organism's genotype determine the organism's phenotype. Some alleles have types called dominant and recessive. These two types can cause different versions of a trait to appear as the organism's phenotype.
A dominant allele causes its version of the trait to appear even when the organism also has a recessive allele for the gene. In pea plants, the F allele, which causes purple flowers, is dominant over the f allele. A pea plant with at least one F allele will have the F allele's version of the flower color trait. So, a plant with the genotype FF or Ff will have purple flowers.
A recessive allele causes its version of the trait to appear only when the organism does not have any dominant alleles for the gene. In pea plants, the f allele, which causes white flowers, is recessive to the F allele. A pea plant with only f alleles will have the f allele's version of the flower color trait. So, a plant with the genotype ff will have white flowers.

Question:
Based on this information, what is this fly's phenotype for the body color trait?

0. a gray body
1. a black body

[Assistant]
The fruit fly's genotype for the body color gene is bb. The fruit fly's genotype of bb has only b alleles. The b allele is for a black body. So, the fruit fly's phenotype for the body color trait must be a black body.
To check this answer, consider whether the fruit fly's alleles are dominant or recessive. The allele for a gray body (B) is dominant over the allele for a black body (b). This means B is a dominant allele, and b is a recessive allele.
The fruit fly's genotype of bb has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, the fruit fly's phenotype for the body color trait must be a black body.
Therefore my final answer is: 1

Question:
Based on this information, what is this plant's phenotype for the stem height trait?

0. a tall stem
1. a short stem

[Assistant]
You need to determine the pea plant's phenotype for the stem height trait. First, consider the alleles in the plant's genotype for the stem height gene. Then, decide whether these alleles are dominant or recessive.
The allele for a short stem (h) is recessive to the allele for a tall stem (H). This means H is a dominant allele, and h is a recessive allele.
The pea plant's genotype of Hh has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, the pea plant's phenotype for the stem height trait must be a tall stem.
Therefore my final answer is: 0

Gravitational potential energy is stored between any two objects. So, for every object on or near Earth, there is gravitational potential energy stored between the object and Earth.
The amount of gravitational potential energy stored between an object and Earth depends on the mass of the object. The amount of gravitational potential energy also depends on the distance between the object and the center of Earth. This distance increases when the object moves higher and decreases when the object moves lower.
If the distance between an object and the center of Earth changes, the gravitational potential energy stored between the object and Earth will change. The table below shows how this change can happen.
When an object's mass stays the same and its distance from the center of Earth... | Gravitational potential energy stored between the object and Earth...
increases | increases
decreases | decreases
stays the same | stays the same

Question:
Complete the statement. Assume that Bobby's mass did not change.
The gravitational potential energy stored between Bobby and Earth () as he rode the escalator.

0. decreased
1. stayed the same
2. increased

[Assistant]
Think about how the distance between Bobby and the center of Earth changed.
The second floor is higher than the first floor. As he rode the escalator toward the second floor, the distance between Bobby and the center of Earth increased. So, the gravitational potential energy stored between Bobby and Earth increased as he rode the escalator.
Therefore my final answer is: 2

Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways.
Inherited traits are passed down from biological parents to their offspring through genes. Genes are pieces of hereditary material that contain the instructions that affect inherited traits. Offspring receive their genes, and therefore gain their inherited traits, from their biological parents. Inherited traits do not need to be learned.
Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment. Parents do not pass acquired traits down to their offspring.

Question:
What information supports the conclusion that Jeffrey inherited this trait?

0. Jeffrey's coworker also has curly hair.
1. Jeffrey's biological father has curly hair.
2. Jeffrey and his biological parents have brown hair.
