Which tense does the sentence use?
Mona will print her name with care. | [
"present tense",
"future tense",
"past tense"
] | 1 | closed choice | grade2 | language science | verbs | Verb tense | Is the sentence in the past, present, or future tense? | Present tense verbs tell you about something that is happening now.
Most present-tense verbs are regular. They have no ending, or they end in -s or -es.
Two verbs are irregular in the present tense, to be and to have. You must remember their forms.
Past tense verbs tell you about something that has already happened.
Most past-tense verbs are regular. They end in -ed.
Some verbs are irregular in the past tense. You must remember their past-tense forms.
Future tense verbs tell you about something that is going to happen.
All future-tense verbs use the word will.
Present | Past | Future
walk, walks | walked | will walk
go, goes | went | will go | The sentence is in future tense. You can tell because it uses will before the main verb, print. The verb tells you about something that is going to happen. |

"chemical change",
"physical change"
] | 1 | closed choice | grade4 | natural science | chemistry | Physical and chemical change | Identify physical and chemical changes | Chemical changes and physical changes are two common ways matter can change.
In a chemical change, the type of matter changes. The types of matter before and after a chemical change are always different.
Burning a piece of paper is a chemical change. When paper gets hot enough, it reacts with oxygen in the air and burns. The paper and oxygen change into ash and smoke.
In a physical change, the type of matter stays the same. The types of matter before and after a physical change are always the same.
Cutting a piece of paper is a physical change. The cut pieces are still made of paper.
A change of state is a type of physical change. For example, ice melting is a physical change. Ice and liquid water are made of the same type of matter: water. | Sewing an apron is a physical change. The fabric and thread that make up the apron get a new shape, but the type of matter in each of them does not change. |

Which of the following contains a vague pronoun reference? | [
"Steven's brother Jim wondered whether he ran fast enough to qualify for the Boston Marathon.",
"Steven's brother Jim wondered whether Steven ran fast enough to qualify for the Boston Marathon."
] | 0 | closed choice | grade11 | language science | writing-strategies | Pronouns | Identify vague pronoun references | When writing, make sure to avoid vague pronoun references. A vague pronoun reference occurs when a pronoun could refer to more than one possible antecedent.
When Lisa and Kim finally landed, she breathed a sigh of relief.
The pronoun she could refer to either Lisa or Kim, so the meaning of the sentence is unclear.
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.
They say that this nail polish dries in less than five minutes.
The pronoun they is used without its antecedent, so the meaning of the sentence is unclear.
This problem can be fixed by replacing the pronoun with its missing antecedent.
The advertisements say that this nail polish dries in less than five minutes. | The first answer choice contains a vague pronoun reference. The pronoun he could refer to Steven or Jim.
The second answer choice shows a possible correction for the vague pronoun reference. He has been replaced with Steven.
Steven's brother Jim wondered whether Steven ran fast enough to qualify for the Boston Marathon. |

What do these two changes have in common?
tearing a piece of paper
breaking a piece of glass | [
"Both are only physical changes.",
"Both are chemical changes.",
"Both are caused by cooling.",
"Both are caused by heating."
] | 0 | closed choice | grade4 | natural science | chemistry | Physical and chemical change | Compare physical and chemical changes | Chemical changes and physical changes are two common ways matter can change.
In a chemical change, the type of matter changes. The types of matter before and after a chemical change are always different.
Some chemical changes are caused by heating or cooling. For example, burning a piece of paper is a chemical change caused by heating. When paper gets hot enough, it reacts with oxygen in the air and burns. The paper and oxygen change into ash and smoke.
In a physical change, the type of matter stays the same. The types of matter before and after a physical change are always the same.
A change of state is a type of physical change. Changes of state can be caused by heating or cooling. For example, ice melting is a physical change that can be caused by heating. Ice and liquid water are made of the same type of matter: water.
The law of conservation of mass says that all physical and chemical changes conserve mass. Conserve means to keep the same. So, the total mass before a physical or chemical change is equal to the total mass after the change. | Step 1: Think about each change.
Tearing a piece of paper is a physical change. The paper tears into pieces. But each piece is still made of paper.
Breaking a piece of glass is a physical change. The glass gets broken into pieces. But each piece is still made of the same type of matter.
Step 2: Look at each answer choice.
Both are only physical changes.
Both changes are physical changes. No new matter is created.
Both are chemical changes.
Both changes are physical changes. They are not chemical changes.
Both are caused by heating.
Neither change is caused by heating.
Both are caused by cooling.
Neither change is caused by cooling. |

What is the volume of a large soup pot? | [
"7 liters",
"7 milliliters"
] | 0 | Select the better estimate. | closed choice | grade5 | natural science | units-and-measurement | Units and measurement | Choose metric units of volume | 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. | The better estimate for the volume of a large soup pot is 7 liters.
7 milliliters is too little. |
Read the following excerpt from a student essay. How can the writer best improve his or her word choice?
When I said that I wanted to take a cooking class, I didn't know what I was getting into. I love cooking, but I'm very shy and hate being in the spotlight. The first time the teacher asked me to do a culinary technique, my hands were sweating profusely. As I held the heavy utility knife in my sweaty hand, it fell to the floor. The class had just started, and I had already made a terrible first impression! My face was red, but I got the knife, put it in the sink, took a clean one, and cut the slab of raw bluefin tuna into paper-thin pieces.

] | 1 | closed choice | grade11 | language science | writing-strategies | Editing and revising | Suggest appropriate revisions | During peer review, you read and respond to a fellow student's writing. While there are many methods and strategies that you can use for reviewing a text, it is generally helpful to frame your suggestions in concrete and constructive ways and to consider the following areas for revision:
Ideas and development: Does the writer express a clear idea and develop it with evidence, examples, or analysis?
Organization: Does the writer order ideas in a clear, logical way so that they build on one another and are easy to follow?
Voice: Does the writer maintain an appropriate voice, such as a formal and objective voice in an academic essay or an engaging and expressive voice in a narrative essay?
Sentence fluency: Does the writer use sentences that vary in structure and length to create a sense of rhythm and flow within and between sentences, or does the writing sound choppy, rambling, or repetitive?
Word choice: Does the writer use words accurately and precisely to create clear, effective, and engaging writing?
Grammar and mechanics: Does the writer follow appropriate conventions, using accurate spelling, punctuation, and grammar to create writing that is correct and easy to read? | The writer could best improve his or her word choice by using more precise verbs.
For example, the writer could replace the underlined words with verbs such as announced, realize, adore, abhor, demonstrate, gripped, clanged, retrieved, deposited, selected, and sliced.

Based on this information, what is Holly's phenotype for the whisker type trait? | [
"straight whiskers",
"curved whiskers"
] | 0 | In a group of Syrian hamsters, some individuals have straight whiskers and others have curved whiskers. In this group, the gene for the whisker type trait has two alleles. The allele for curved whiskers (h) is recessive to the allele for straight whiskers (H).
Holly is a Syrian hamster from this group. Holly has the heterozygous genotype Hh for the whisker type gene. | closed choice | grade8 | natural science | biology | Genes to traits | Genetics vocabulary: dominant and recessive | 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 gene—one 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. | You need to determine Holly's phenotype for the whisker type trait. First, consider the alleles in Holly's genotype for the whisker type gene. Then, decide whether these alleles are dominant or recessive.
The allele for curved whiskers (h) is recessive to the allele for straight whiskers (H). This means H is a dominant allele, and h is a recessive allele.
Holly'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, Holly's phenotype for the whisker type trait must be straight whiskers. |

] | 2 | closed choice | grade2 | natural science | physics | States of matter | Identify solids and liquids | Solid and liquid are states of matter. Matter is anything that takes up space. Matter can come in different states, or forms.
When matter is a solid, it has a shape of its own.
Some solids can be bent or broken easily. Others are hard to bend or break.
A glass cup is a solid. A sock is also a solid.
When matter is a liquid, it takes the shape of its container.
Think about pouring a liquid from a cup into a bottle. The shape of the liquid is different in the cup than in the bottle. But the liquid still takes up the same amount of space.
Juice is a liquid. Honey is also a liquid. | ||

Verbal irony involves saying one thing but implying something very different. People often use verbal irony when they are being sarcastic.
Olivia seems thrilled that her car keeps breaking down.
Each breakdown is as enjoyable as a punch to the face. | The text uses a pun, a word or phrase that humorously suggests more than one meaning.
Impossible to put down means that the book is so good that it is hard to stop reading. The phrase impossible to put down is also a joke about anti-gravity: if gravity pulls things down, perhaps anti-gravity does the opposite and makes them impossible to put down. |

one heating lamp | closed choice | grade8 | natural science | science-and-engineering-practices | Designing experiments | Identify questions that can be investigated with a set of materials | Experiments can be designed to answer specific questions. When designing an experiment, you must identify the supplies that are necessary to answer your question. In order to do this, you need to figure out what will be tested and what will be measured during the experiment.
Imagine that you are wondering if plants grow to different heights when planted in different types of soil. How might you decide what supplies are necessary to conduct this experiment?
First, you need to identify the part of the experiment that will be tested, which is the independent variable. This is usually the part of the experiment that is different or changed. In this case, you would like to know how plants grow in different types of soil. So, you must have different types of soil available.
Next, you need to identify the part of the experiment that will be measured or observed, which is the dependent variable. In this experiment, you would like to know if some plants grow taller than others. So, you must be able to compare the plants' heights. To do this, you can observe which plants are taller by looking at them, or you can measure their exact heights with a meterstick.
So, if you have different types of soil and can observe or measure the heights of your plants, then you have the supplies you need to investigate your question with an experiment! | |

] | 1 | closed choice | grade8 | social science | economics | Supply and demand | Understand overall supply and demand | Overall supply is the total amount of a good or service that producers make and sell. There are several things that can make overall supply go up or down. The table below shows how changes to these things might affect overall supply.
| Resources | Number of producers or suppliers | Expected change in demand
Supply goes up | when resources cost less or are easier to get | when there are more producers or suppliers | when demand is expected to go up
Supply goes down | when resources cost more or are harder to get | when there are fewer producers or suppliers | when demand is expected to go down
Producers are people or companies that make goods or provide services. Suppliers are people or companies that sell goods or services. New inventions or technologies can also help workers produce goods and services more quickly. As a result of these changes, the supply of a good or service will often go up. | When four men's clothing stores closed on Main Street, the number of suppliers went down. There were fewer stores selling men's shirts. So, the supply of men's shirts probably went down. |

Based on this information, what is Squirt's phenotype for the tail spots trait? | [

] | 0 | In a group of guppies, some individuals have a spotted tail and others have an unspotted tail. In this group, the gene for the tail spots trait has two alleles. The allele for a spotted tail (I) is dominant over the allele for an unspotted tail (i).
Squirt is a guppy from this group. Squirt has the heterozygous genotype Ii for the tail spots gene. | closed choice | grade8 | natural science | biology | Genes to traits | Genetics vocabulary: dominant and recessive | 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 gene—one 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. | You need to determine Squirt's phenotype for the tail spots trait. First, consider the alleles in Squirt's genotype for the tail spots gene. Then, decide whether these alleles are dominant or recessive.
The allele for a spotted tail (I) is dominant over the allele for an unspotted tail (i). This means I is a dominant allele, and i is a recessive allele.
Squirt's genotype of Ii 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, Squirt's phenotype for the tail spots trait must be a spotted tail. |

Imagine that you are wondering if plants grow to different heights when planted in different types of soil. How might you decide what supplies are necessary to conduct this experiment?
First, you need to identify the part of the experiment that will be tested, which is the independent variable. This is usually the part of the experiment that is different or changed. In this case, you would like to know how plants grow in different types of soil. So, you must have different types of soil available.
Next, you need to identify the part of the experiment that will be measured or observed, which is the dependent variable. In this experiment, you would like to know if some plants grow taller than others. So, you must be able to compare the plants' heights. To do this, you can observe which plants are taller by looking at them, or you can measure their exact heights with a meterstick.

Zazu has the homozygous genotype RR for the cheek color gene. | closed choice | grade8 | natural science | biology | Genes to traits | Genetics vocabulary: dominant and recessive | 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 gene—one allele inherited from each parent.

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.

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. | Zazu's genotype for the cheek color gene is RR. Zazu's genotype of RR has only R allelles. The R allele is for bright orange cheeks. So, Zazu's phenotype for the cheek color trait must be bright orange cheeks.
To check this answer, consider whether Zazu's alleles are dominant or recessive. The allele for pale orange cheeks (r) is recessive to the allele for bright orange cheeks (R). This means R is a dominant allele, and r is a recessive allele.
Zazu's genotype of RR has two dominant alleles. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Zazu's phenotype for the cheek color trait must be bright orange cheeks. |

What do these two changes have in common?

"Both are caused by heating.",
"Both are chemical changes.",
"Both are caused by cooling.",
"Both are only physical changes."
] | 1 | closed choice | grade7 | natural science | chemistry | Chemical reactions | Compare physical and chemical changes | 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 different molecules. The types of molecules in matter before and after a chemical change are always different.
Some chemical changes are caused by heating or cooling. For example, burning a piece of paper is a chemical change caused by heating. As paper burns, paper molecules react with oxygen molecules in the air. This reaction breaks the chemical bonds in the molecules. The atoms then link together in a different way to form different molecules. For example, carbon dioxide molecules are formed 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. Changes of state can be caused by heating or cooling. For example, water vaporizing is a physical change that can be caused by heating. Liquid water and water vapor are made of the same type of matter: water.
The law of conservation of mass says that all physical and chemical changes conserve mass. Conserve means to keep the same. So, the total mass before a physical or chemical change is equal to the total mass after the change. | Step 1: Think about each change.
A banana getting ripe on the counter is a chemical change. As a banana ripens, the type of matter in it changes. The peel changes color and the inside becomes softer and sweeter.
Concrete hardening is a chemical change. The chemicals in the concrete react with each other to form a different type of matter. The new matter is hard and strong.

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.

Which metal paper clip has less thermal energy? | [
"the colder metal paper clip",
"the hotter metal paper clip"
] | 0 | Two metal paper clips are identical except for their temperatures. | closed choice | grade6 | natural science | physics | Thermal energy | How are temperature and mass related to thermal energy? | Matter is made of tiny particles called atoms. Atoms are always moving.
The energy of moving atoms is called thermal energy. The total amount of thermal energy in matter depends on three things: the type of matter, the amount of matter, and how fast the atoms are moving.
Temperature measures how hot or cold matter is. If the atoms in matter slow down, the temperature goes down. The matter now has both less thermal energy and a lower temperature.
What happens if the amount of matter changes? A 2-kilogram brick at 70°F has twice as much thermal energy as a 1-kilogram brick at 70°F. The two bricks have the same temperature, but the larger brick has twice as many atoms. So, it has twice as much thermal energy. | The two metal paper clips are made of the same material and have the same mass. So, the colder metal paper clip has less thermal energy. |

] | 1 | closed choice | grade7 | natural science | biology | Photosynthesis | Identify the photosynthetic organism | Organisms that carry out photosynthesis are called photosynthetic organisms. During photosynthesis, these organisms use light energy, carbon dioxide, and water to produce sugars and oxygen.
Photosynthetic organisms also often have the following characteristics:
They are producers, which are organisms that make their own food inside their cells. Because producers make their own food, they typically do not eat other organisms.
Their cells contain chloroplasts, which are cell structures where photosynthesis occurs.
Their chloroplasts often contain a green substance called chlorophyll. Chlorophyll captures light energy from the Sun to power photosynthesis.
They use the sugars they produce during photosynthesis as food. This food provides energy that helps the organisms live, grow, and reproduce. | This organism is photosynthetic:
The text tells you that Sphagnum mosses get energy from the sugars they make using carbon dioxide and water. This is evidence that the Sphagnum moss is a photosynthetic organism.

Which drop of dish soap has a lower temperature? | [
"the drop of dish soap with more thermal energy",
"the drop of dish soap with less thermal energy"
] | 1 | Two drops of dish soap are identical except for their thermal energies. | closed choice | grade6 | natural science | physics | Thermal energy | How are temperature and mass related to thermal energy? | Matter is made of tiny particles called atoms. Atoms are always moving.
The energy of moving atoms is called thermal energy. The total amount of thermal energy in matter depends on three things: the type of matter, the amount of matter, and how fast the atoms are moving.
Temperature measures how hot or cold matter is. If the atoms in matter slow down, the temperature goes down. The matter now has both less thermal energy and a lower temperature.
What happens if the amount of matter changes? A 2-kilogram brick at 70°F has twice as much thermal energy as a 1-kilogram brick at 70°F. The two bricks have the same temperature, but the larger brick has twice as many atoms. So, it has twice as much thermal energy. | The two drops of dish soap are made of the same material and have the same mass. So, the drop of dish soap with less thermal energy has a lower temperature. |
