Formal writing is used for essays, business letters, and reports. The following types of informal language should be avoided in formal writing:
Type | Examples
slang | cool, awesome
idioms | knock your socks off
conversational language | gonna, kinda, yeah
abbreviated language | ASAP, FYI
overly simple or imprecise language | he got some stuff at the store
contractions | can't, won't
Contractions are not as informal as the other types, but they should be used sparingly in formal writing.

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.

An object's speed tells you how fast the object is moving. Speed depends on both distance and time.
Distance tells you how far the object has moved. One unit used to measure distance is the mile.
Time tells you how long the object has spent moving. One unit used to measure time is the hour.
Think about objects moving for the same amount of time. The object that is moving the fastest will go the farthest distance in that time. It is moving at the highest speed.

Question:
Compare the motion of three motorboats. Which motorboat was moving at the highest speed?

0. a motorboat that moved 210miles west in 5hours
1. a motorboat that moved 60miles east in 5hours
2. a motorboat that moved 70miles south in 5hours

[Assistant]
Look at the distance each motorboat moved and the time it took to move that distance. The direction each motorboat moved does not affect its speed.
Notice that each motorboat moved for 5 hours. The motorboat that moved 210 miles moved the farthest distance in that time. So, that motorboat must have moved at the highest speed.

There is a surplus if there is too much for sale at a given price.
There is a shortage if there is not enough for sale at a given price.
Surpluses and shortages usually happen when people who are selling goods or services charge too much or too little.
When the price is too high, consumers will not want to buy much of the good or service. The quantity demanded will be less than the quantity supplied. So, there will be a surplus.
When the price is too low, too many consumers will want to buy the good or service. The quantity demanded will be more than the quantity supplied. So, there will be a shortage.

Question:
Is there a surplus or a shortage of plane tickets?

Every substance around you is made of one or more chemical elements, or types of atoms. Substances that are made of only one chemical element are elementary substances. Substances that are made of two or more chemical elements bonded together are compounds.
Every chemical element is represented by its own symbol. For some elements, the symbol is one capital letter. For other elements, the symbol is one capital letter and one lowercase letter. For example, the symbol for the element fluorine is F, and the symbol for the element beryllium is Be.
The symbol for each element in a substance is shown in the substance's chemical formula.
An elementary substance is represented by a chemical formula that contains only one symbol.
The symbol may be followed by a subscript. A subscript is text that is smaller and placed lower than the normal line of text. A subscript is included when the atoms in the elementary substance are bonded to form molecules. The subscript tells you the number of atoms in each molecule.
For example, the chemical formula for the elementary substance oxygen is O2. The formula has a subscript of 2. This subscript tells you that there are two atoms in the molecule represented by this chemical formula.
The chemical element represented by the symbol O is also called oxygen. So, the formula O2 tells you that each molecule of O2 contains two oxygen atoms.
A compound is represented by a chemical formula that contains multiple symbols.
For example, in the compound beryllium fluoride, there is one beryllium atom for every two fluorine atoms. This combination is shown in the compound's chemical formula, BeF2. In the formula, the symbol Be represents one beryllium atom. The symbol F followed by the subscript 2 represents two fluorine atoms.

Question:
Complete the statement.
Chloroform is ().

0. a compound
1. an elementary substance

[Assistant]
You can tell whether chloroform is an elementary substance or a compound by counting the number of symbols in its chemical formula. A symbol contains either one capital letter or a capital letter followed by one or two lowercase letters.
The chemical formula for chloroform is CHCl3. This formula contains three symbols: C for carbon, H for hydrogen, and Cl for chlorine. So, the formula tells you that chloroform is made of three chemical elements bonded together.
Substances made of two or more chemical elements bonded together are compounds. So, chloroform is a compound.
Therefore my final answer is: 0

Look at the distance each train moved and the time it took to move that distance.
One train moved 635 kilometers in 5 hours.
The other train moved 605 kilometers in 5 hours.
Notice that each train spent the same amount of time moving. The train that moved 635 kilometers moved a farther distance in that time. So, that train must have moved at a higher speed.
Therefore my final answer is: 0

Minerals are the building blocks of rocks. A rock can be made of one or more minerals.
Minerals and rocks have the following properties:
Property | Mineral | Rock
It is a solid. | Yes | Yes
It is formed in nature. | Yes | Yes
It is not made by organisms. | Yes | Yes
It is a pure substance. | Yes | No
It has a fixed crystal structure. | Yes | No
You can use these properties to tell whether a substance is a mineral, a rock, or neither.
Look closely at the last three properties:
Minerals and rocks are not made by organisms.
Organisms make their own body parts. For example, snails and clams make their shells. Because they are made by organisms, body parts cannot be  minerals or rocks.
Humans are organisms too. So, substances that humans make by hand or in factories are not minerals or rocks.
A mineral is a pure substance, but a rock is not.
A pure substance is made of only one type of matter.  Minerals are pure substances, but rocks are not. Instead, all rocks are mixtures.
A mineral has a fixed crystal structure, but a rock does not.
The crystal structure of a substance tells you how the atoms or molecules in the substance are arranged. Different types of minerals have different crystal structures, but all minerals have a fixed crystal structure. This means that the atoms and molecules in different pieces of the same type of mineral are always arranged the same way.
However, rocks do not have a fixed crystal structure. So, the arrangement of atoms or molecules in different pieces of the same type of rock may be different!

Question:
Select the one substance that is not a mineral.

0. Native gold is a pure substance. It is not made by living things.
1. A shark's tooth is not a pure substance. It is formed in nature.
2. Potassium feldspar is a pure substance. It is a solid.

[Assistant]
Compare the properties of each substance to the properties of minerals. Select the substance whose properties do not match those of minerals.
Native gold is a mineral.
Potassium feldspar is a mineral.
A shark's tooth is not a pure substance. But all minerals are pure substances.
So, a shark's tooth is not a mineral.
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.

Question:
Based on this information, what is this fruit fly's genotype for the body color gene?

0. BB
1. a gray body

[Assistant]
An organism's genotype for a gene is its combination of alleles for that gene. The fruit fly has two alleles for a gray body (B). So, the fly's genotype for the body color gene is BB.

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 a pencil is 8 long. You might be thinking, 8 what? Is the pencil 8 inches long? 8 feet? 8 miles?
The number 8 on its own does not give you much information about the length of the pencil. That is because the units are missing.
Now look at the drawing of the pencil and the ruler. The ruler shows that the units are inches. So, the length of the pencil is 8 inches.
There are 12 inches in 1 foot. So, 1 inch is much shorter than 1 foot.
There are 3 feet in 1 yard. So, 1 foot is shorter than 1 yard.

Question:
How long is a basketball court?

An object's velocity describes its speed and its direction.
An object has a constant velocity when neither its speed nor its direction is changing. So, an object has a constant velocity when the object is:
moving in a straight line at a constant speed, or
remaining motionless.
If an object does not have a constant velocity, the object is accelerating. An object is accelerating when either its speed or its direction is changing. So, an object is accelerating when the object is:
speeding up,
slowing down, or
changing direction.

Question:
Which statement describes the asteroid's motion?

0. The asteroid has a constant velocity.
1. The asteroid is accelerating.

[Assistant]
The asteroid is moving in a straight line at a constant speed. So, the asteroid has a constant velocity.

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 plant's phenotype for the flower position trait?

0. terminal flowers
1. axial flowers

[Assistant]
The pea plant's genotype for the flower position gene is ff. The pea plant's genotype of ff has only f alleles. The f allele is for terminal flowers. So, the pea plant's phenotype for the flower position trait must be terminal flowers.
To check this answer, consider whether the pea plant's alleles are dominant or recessive. The allele for terminal flowers (f) is recessive to the allele for axial flowers (F). This means F is a dominant allele, and f is a recessive allele.
The pea plant's genotype of ff 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 pea plant's phenotype for the flower position trait must be terminal flowers.
Therefore my final answer is: 0

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.

There are more than 100 different chemical elements, or types of atoms. Chemical elements make up all of the substances around you.
A substance may be composed of one chemical element or multiple chemical elements. Substances that are composed of only one chemical element are elementary substances. Substances that are composed of multiple chemical elements bonded together are compounds.
Every chemical element is represented by its own atomic symbol. An atomic symbol may consist of one capital letter, or it may consist of a capital letter followed by a lowercase letter. For example, the atomic symbol for the chemical element fluorine is F, and the atomic symbol for the chemical element beryllium is Be.
The atomic symbol for each chemical element in a substance is shown in the substance's chemical formula.
An elementary substance is represented by a chemical formula that contains only one atomic symbol.
The atomic symbol in a chemical formula may be followed by a small number written lower than the symbol. This number is called a subscript. A subscript is included when the atoms in the elementary substance are bonded to form molecules. The subscript shows how many atoms are in each molecule.
For example, the chemical formula for the elementary substance oxygen, O2, has a subscript of 2. This subscript shows that the atomic symbol O represents two atoms. The elementary substance O2 and the chemical element represented by the atomic symbol O are both named oxygen. So, the formula tells you that each molecule of O2 contains two oxygen atoms.
A compound is represented by a chemical formula that contains multiple atomic symbols.
The chemical elements in a compound are bonded together in a fixed ratio. This ratio is shown in a compound's chemical formula.
For example, in the compound beryllium fluoride, there is one beryllium atom for every two fluorine atoms. So, the ratio of beryllium atoms to fluorine atoms is 1 to 2. This ratio is shown in the chemical formula for beryllium fluoride, BeF2. There is no subscript following the atomic symbol Be because that symbol represents one atom. The subscript 2 follows the atomic symbol F to show that the symbol represents two atoms.

Question:
Complete the statement.
Lithium chloride is ().

0. an elementary substance
1. a compound

[Assistant]
You can tell whether lithium chloride is an elementary substance or a compound by counting the number of atomic symbols in its chemical formula. An atomic symbol consists of either one capital letter or a capital letter followed by one or two lowercase letters.
The chemical formula for lithium chloride, LiCl, contains two atomic symbols: Li for lithium and Cl for chlorine. So, the formula tells you that lithium chloride is composed of two chemical elements bonded together.
Since lithium chloride is composed of multiple chemical elements bonded together, lithium chloride is a compound.
Therefore my final answer is: 1

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 Finn inherited this trait?

A force is a push or a pull.
A force can make an object start moving or stop an object that is moving. A force can also make an object speed up, slow down, or change direction.
Forces can be different sizes.
Think about trying to move a heavy object and a light object. Imagine you want to move them at the same speed. You will need to use a larger force to move the heavy object.

Question:
Each bus takes the same amount of time to stop. Which school bus needs a larger force to come to a stop?

0. a school bus carrying 500 pounds
1. a school bus carrying 550 pounds

[Assistant]
Look for the school bus that is heavier.
A school bus carrying 550 pounds is heavier than a school bus carrying 500 pounds. So, the school bus carrying 550 pounds needs a larger force to come to a stop in the same amount of time as the other bus.
Therefore my final answer is: 1


[User]
According to Newton's third law, for every force, there is an equal and opposite force. This means that if one object is applying a force on a second object, the second object must also be applying a force on the first object, but in the opposite direction.
For example, if your hand is pushing down on a table, the table is also pushing up on your hand. Or, if you are pulling forward on a rope, the rope is also pulling back on you.

Question:
According to Newton's third law, what other force must be happening?

0. The door is pulling on Abigail's hand.
1. The door is pushing on Abigail's hand.

[Assistant]
Abigail's hand is pushing on the door. So, Newton's third law tells you that the door is pushing on Abigail's hand.
Therefore my final answer is: 1

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.

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.

Question:

Minerals are the building blocks of rocks. A rock can be made of one or more minerals.
Minerals and rocks have the following properties:
Property | Mineral | Rock
It is a solid. | Yes | Yes
It is formed in nature. | Yes | Yes
It is not made by organisms. | Yes | Yes
It is a pure substance. | Yes | No
It has a fixed crystal structure. | Yes | No
You can use these properties to tell whether a substance is a mineral, a rock, or neither.
Look closely at the last three properties:
Minerals and rocks are not made by organisms.
Organisms make their own body parts. For example, snails and clams make their shells. Because they are made by organisms, body parts cannot be  minerals or rocks.
Humans are organisms too. So, substances that humans make by hand or in factories are not minerals or rocks.
A mineral is a pure substance, but a rock is not.
A pure substance is made of only one type of matter.  Minerals are pure substances, but rocks are not. Instead, all rocks are mixtures.
A mineral has a fixed crystal structure, but a rock does not.
The crystal structure of a substance tells you how the atoms or molecules in the substance are arranged. Different types of minerals have different crystal structures, but all minerals have a fixed crystal structure. This means that the atoms and molecules in different pieces of the same type of mineral are always arranged the same way.
However, rocks do not have a fixed crystal structure. So, the arrangement of atoms or molecules in different pieces of the same type of rock may be different!

Question:
Select the one substance that is not a mineral.

0. Hornblende is formed in nature. It is a pure substance.
1. Diamond is a pure substance. It is formed in nature.
2. Candle wax is not a pure substance. It is made by humans.

[Assistant]
Compare the properties of each substance to the properties of minerals. Select the substance whose properties do not match those of minerals.
Candle wax is not a pure substance. But all minerals are pure substances.
Candle wax is made by humans. But minerals are not made by living things.
So, candle wax is not a mineral.
Diamond is a mineral.
Hornblende is a mineral.
Therefore my final answer is: 2

Every substance around you is made of one or more chemical elements, or types of atoms. Substances that are made of only one chemical element are elementary substances. Substances that are made of two or more chemical elements bonded together are compounds.
Every chemical element is represented by its own symbol. For some elements, the symbol is one capital letter. For other elements, the symbol is one capital letter and one lowercase letter. For example, the symbol for the element fluorine is F, and the symbol for the element beryllium is Be.
The symbol for each element in a substance is shown in the substance's chemical formula.
An elementary substance is represented by a chemical formula that contains only one symbol.
The symbol may be followed by a subscript. A subscript is text that is smaller and placed lower than the normal line of text. A subscript is included when the atoms in the elementary substance are bonded to form molecules. The subscript tells you the number of atoms in each molecule.
For example, the chemical formula for the elementary substance oxygen is O2. The formula has a subscript of 2. This subscript tells you that there are two atoms in the molecule represented by this chemical formula.
The chemical element represented by the symbol O is also called oxygen. So, the formula O2 tells you that each molecule of O2 contains two oxygen atoms.
A compound is represented by a chemical formula that contains multiple symbols.
For example, in the compound beryllium fluoride, there is one beryllium atom for every two fluorine atoms. This combination is shown in the compound's chemical formula, BeF2. In the formula, the symbol Be represents one beryllium atom. The symbol F followed by the subscript 2 represents two fluorine atoms.

Question:
Select the elementary substance.

0. hydrogen peroxide (H2O2)
1. magnesium (Mg)
2. hydrazine (N2H4)

[Assistant]
Look at the chemical formula for each substance, and count the number of symbols in the formula. Then, decide if the substance is an elementary substance. The chemical formula for hydrogen peroxide contains two symbols: H for hydrogen and O for oxygen. So, hydrogen peroxide is made of two chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, hydrogen peroxide is a compound, not an elementary substance. The chemical formula for magnesium contains one symbol: Mg. So, magnesium is made of one chemical element. Substances that are made of one chemical element are elementary substances. So, magnesium is an elementary substance. The chemical formula for hydrazine contains two symbols: N for nitrogen and H for hydrogen. So, hydrazine is made of two chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, hydrazine is a compound, not an elementary substance.
Therefore my final answer is: 1

Temperature measures how hot or cold matter is. If the particles in matter slow down, the temperature goes down. The matter now has both less thermal energy and a lower temperature.

Question:
Which object has less thermal energy?

0. a 700-gram rock at a temperature of 115C
1. a 700-gram rock at a temperature of 120C

[Assistant]
The two rocks have the same mass but different temperatures. Since the 115C rock is colder than the 120C rock, it has less thermal energy.
Therefore my final answer is: 0
