Demonstration: Which solution has a higher concentration of pink particles?
Context: The diagram below is a model of two solutions. Each pink ball represents one particle of solute.
Options: (A) Solution A (B) Solution B (C) neither; their concentrations are the same
Answer: The answer is A
Rationale: To determine which solution has a higher concentration of pink particles, we need to compare the number of pink particles in each solution. In the image, there are 40 pink particles in Solution A and 40 pink particles in Solution B. Since the number of particles is the same in both solutions, their concentrations are also the same. Therefore, the answer is (C) neither; their concentrations are the same.
Wrong Rationale Steps: In the image, there are 40 pink particles in Solution A and 40 pink particles in Solution B. Since the number of particles is the same in both solutions, their concentrations are also the same.
Missing Skill: The model did not accurately observe the number of pink particles in each flask as shown in the image.
Query: Which of the following organisms is the omnivore in this food web?
Context: Below is a food web from Little Rock Lake, a freshwater lake ecosystem in Wisconsin.
A food web models how the matter eaten by organisms moves through an ecosystem. The arrows in a food web represent how matter moves between organisms in an ecosystem.
Options: (A) shiner (B) black crappie (C) copepod
Answer: The answer is C
Wrong Rationale: A food web is a model.
A food web shows where organisms in an ecosystem get their food. Models can make things in nature easier to understand because models can represent complex things in a simpler way. If a food web showed every organism in an ecosystem, the food web would be hard to understand. So, each food web shows how some organisms in an ecosystem can get their food.
Arrows show how matter moves.
A food web has arrows that point from one organism to another. Each arrow shows the direction that matter moves when one organism eats another organism. An arrow starts from the organism that is eaten. The arrow points to the organism that is doing the eating.
An organism in a food web can have more than one arrow pointing from it. This shows that the organism is eaten by more than one other organism in the food web.
An organism in a food web can also have more than one arrow pointing to it. This shows that the organism eats more than one other organism in the food web. Omnivores are consumers that eat both producers and other consumers. So, an omnivore has arrows pointing to it from at least one producer and at least one consumer.
The shiner has an arrow pointing to it from the green algae, which is a producer. The shiner also has an arrow pointing to it from the rotifer, which is a consumer. The shiner eats a producer and a consumer, so it is an omnivore.
The black crappie has an arrow pointing to it from the water flea, which is a consumer. The black crappie also has an arrow pointing to it from the rotifer, which is a consumer. The black crappie eats a consumer and a producer, so it is an omnivore.
The copepod has only one arrow pointing to it. This arrow starts from the green algae, which is a producer. So, the copepod is a consumer but not an omnivore. The answer is B.
Key Wrong Steps: The black crappie has an arrow pointing to it from the water flea, which is a consumer. The black crappie also has an arrow pointing to it from the rotifer, which is a consumer. The black crappie eats a consumer and a producer, so it is an omnivore. The copepod has only one arrow pointing to it. This arrow starts from the green algae, which is a producer.
Missing Skill:

The missing skill in this case is the ability to accurately interpret the arrows in a food web. The key wrong steps show that the user incorrectly assumed that an organism is an omnivore if it has arrows pointing to it from both producers and consumers. However, this is not correct. The correct interpretation is that an organism is an omnivore if it has arrows pointing to it from at least one producer and at least one consumer. In this case, the copepod only has one arrow pointing to it from a producer (green algae), so it is a consumer but not an omnivore.

Query: Which of the following contains a vague pronoun reference?
Context: N/A
Options: (A) At the conference, the authors met with some publishers to discuss their new books. (B) At the conference, the authors discussed their new books with some publishers.
Answer: The answer is A
Wrong Rationale: 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 second answer choice contains a vague pronoun reference. The pronoun their could refer to the authors' or the publishers'.
At the conference, the authors discussed their new books with some publishers.
The first answer choice shows a possible correction for the vague pronoun reference. The text has been rewritten so that the meaning is clear.
At the conference, the authors met with some publishers to discuss their new books. The answer is B.
Key Wrong Steps: 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 second answer choice contains a vague pronoun reference. The pronoun their could refer to the authors' or the publishers'.
Missing Skill:

The missing skill is identifying and correcting vague pronoun references in writing.

Query: Which solution has a higher concentration of purple particles?
Context: The diagram below is a model of two solutions. Each purple ball represents one particle of solute.
Options: (A) Solution B (B) Solution A (C) neither; their concentrations are the same
Answer: The answer is A
Wrong Rationale: A solution is made up of two or more substances that are completely mixed. In a solution, solute particles are mixed into a solvent. The solute cannot be separated from the solvent by a filter. For example, if you stir a spoonful of salt into a cup of water, the salt will mix into the water to make a saltwater solution. In this case, the salt is the solute. The water is the solvent.
The concentration of a solute in a solution is a measure of the ratio of solute to solvent. Concentration can be described in terms of particles of solute per volume of solvent.
concentration = particles of solute / volume of solvent In Solution A and Solution B, the purple particles represent the solute. To figure out which solution has a higher concentration of purple particles, look at both the number of purple particles and the volume of the solvent in each container.
Use the concentration formula to find the number of purple particles per milliliter.
Solution A has more purple particles per milliliter. So, Solution A has a higher concentration of purple particles. The answer is B.
Key Wrong Steps: concentration = particles of solute / volume of solvent In Solution A and Solution B, the purple particles represent the solute.

Query: Look at the models of molecules below. Select the elementary substance.
Context: N/A
Options: (A) ozone (B) 2-chloroethanol (C) benzene
Answer: The answer is A
Wrong Rationale: 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 boron is B, and the atomic symbol for the chemical element chlorine is Cl.
Scientists use different types of models to represent substances whose atoms are bonded in different ways. One type of model is a ball-and-stick model. The ball-and-stick model below represents a molecule of the compound boron trichloride.
In a ball-and-stick model, the balls represent atoms, and the sticks represent bonds. Notice that the balls in the model above are not all the same color. Each color represents a different chemical element. The legend shows the color and the atomic symbol for each chemical element in the substance. The answer is C.
Key Wrong Steps: Notice that the balls in the model above are not all the same color. Each color represents a different chemical element. The legend shows the color and the atomic symbol for each chemical element in the substance. The answer is C.
Missing Skill:

The missing skill in this case is the ability to correctly identify the chemical element represented by each ball in the model and determine if the substance is an elementary substance or a compound.

Query: Will these magnets attract or repel each other?
Context: Two magnets are placed as shown.
Options: (A) repel (B) attract
Answer: The answer is A
Wrong Rationale: Magnets can pull or push on other magnets without touching them. When magnets attract, they pull together. When magnets repel, they push apart. These pulls and pushes are called magnetic forces.
Magnetic forces are strongest at the magnets' poles, or ends. Every magnet has two poles: a north pole (N) and a south pole (S).
Here are some examples of magnets. Their poles are shown in different colors and labeled.
Whether a magnet attracts or repels other magnets depends on the positions of its poles.
If opposite poles are closest to each other, the magnets attract. The magnets in the pair below attract.
If the same, or like, poles are closest to each other, the magnets repel. The magnets in both pairs below repel. To predict if these magnets will attract or repel, look at which poles are closest to each other.
The south pole of one magnet is closest to the north pole of the other magnet. Opposite poles attract. So, these magnets will attract each other. The answer is B.
Key Wrong Steps:
Missing Skill:

The missing skill in this scenario is the ability to identify the positions of the poles of the magnets and determine whether they are opposite or like poles.

Query: Which animal's mouth is also adapted for gnawing?
Context: Nutrias eat plant parts such as stems and branches. They eat by biting off small pieces at a time, or gnawing. The 's mouth is adapted for gnawing.
Figure: nutria.
Options: (A) Podolsk mole rat (B) tamandua
Answer: The answer is A
Wrong Rationale: An adaptation is an inherited trait that helps an organism survive or reproduce. Adaptations can include both body parts and behaviors.
The shape of an animal's mouth is one example of an adaptation. Animals' mouths can be adapted in different ways. For example, a large mouth with sharp teeth might help an animal tear through meat. A long, thin mouth might help an animal catch insects that live in holes. Animals that eat similar food often have similar mouths. Look at the picture of the nutria.
The nutria has large front teeth. Its mouth is adapted for gnawing. The large front teeth can help the nutria break off pieces of food that it can swallow.
Now look at each animal. Figure out which animal has a similar adaptation.
The tamandua has large front teeth. Its mouth is adapted for gnawing.
The Podolsk mole rat has small teeth. Its mouth is not adapted for gnawing. The Podolsk mole rat uses its mouth to eat soil. The answer is B.
Key Wrong Steps: Animals that eat similar food often have similar mouths. Look at the picture of the nutria. The nutria has large front teeth. Its mouth is adapted for gnawing. The large front teeth can help the nutria break off pieces of food that it can swallow.
Missing Skill:

The missing skill in this case is the ability to analyze and differentiate between different adaptations and their suitability for a specific behavior. In the Wrong Rationale Steps, the reasoning is based solely on the presence of large front teeth in both animals (the nutria and tamandua), assuming that similar teeth mean similar adaptations. However, it is important to understand that adaptations can vary in their specificity and effectiveness for different behaviors. In this case, the nutria's large front teeth are adapted for gnawing, while the tamandua's large front teeth are adapted for tearing and catching prey.

It started raining, so we ran inside. Sacramento is the capital of California, the state government meets there is a sentence fragment. It is missing a subject. The answer is A.
Key Wrong Steps: It is usually missing a subject or a verb. Knows the answer. This is a sentence fragment. It is missing a subject. Who knows the answer?
Missing Skill:

The missing skill in this query is the ability to identify a complete sentence and differentiate it from a sentence fragment. The user's rationale correctly states that a sentence is a group of words that forms a complete thought and has both a subject and a verb. However, they incorrectly identify option B as a sentence fragment, stating that it is missing a subject. In reality, option B "All the goats, cows, and horses on the farm" is a complete sentence because it has a subject (All the goats, cows, and horses) and a verb (on the farm). Therefore, the missing skill is the understanding of what constitutes a complete sentence.

Query: In this experiment, which were part of a control group?
Context: The passage below describes an experiment.

Jeanette and Bryant were taking a snowboarding class. During the class, their instructor said they would go faster if they applied wax to the undersides of their snowboards.
After the class, Jeanette applied a thin layer of wax to the underside of a snowboard and rode the board straight down a hill. Then, she removed the wax and rode the snowboard straight down the hill again. Bryant timed how long each ride took. Jeanette repeated these rides on four other snowboards, alternating whether she first rode with or without wax.
Figure: a snowboarder.
Options: (A) the snowboards with wax removed (B) the snowboards with wax added
Answer: The answer is A
Wrong Rationale: Experiments have variables, or parts that change. You can design an experiment to investigate whether changing a variable between different groups has a specific outcome.
For example, imagine you want to find out whether adding fertilizer to soil affects the height of pea plants. You could investigate this question with the following experiment:
You grow one group of pea plants in soil with fertilizer and measure the height of the plants. This group shows you what happens when fertilizer is added to soil. Since fertilizer is the variable whose effect you are investigating, this group is an experimental group.
You grow another group of pea plants in soil without fertilizer and measure the height of the plants. Since this group shows you what happens when fertilizer is not added to the soil, it is a control group.
By comparing the results from the experimental group to the results from the control group, you can conclude whether adding fertilizer to the soil affects pea plant height. In this experiment, Jeanette and Bryant investigated whether applying wax to snowboards affects how fast snowboarders go. The snowboards with wax added were not timed to go down the hill. So, they were part of a control group. The answer is B.
Key Wrong Steps: You grow another group of pea plants in soil without fertilizer and measure the height of the plants.

In the image, there are 40 pink particles in Solution A and 40 pink particles in Solution B. Since the number of particles is the same in both solutions, their concentrations are also the same. Therefore, the answer is (C) neither; their concentrations are the same.
Wrong Rationale Steps: In the image, there are 40 pink particles in Solution A and 40 pink particles in Solution B. Since the number of particles is the same in both solutions, their concentrations are also the same.
Missing Skill: The model did not accurately observe the number of pink particles in each flask as shown in the image.
Query: Which is the most flexible?
Context: N/A
Options: (A) glass bowl (B) wood board (C) metal hair clip
Answer: The answer is C
Wrong Rationale: Every object is made of one or more materials. A material is a type of matter. Wood, glass, metal, and plastic are common materials.
A material has different properties. A material's properties tell you how it looks, feels, tastes, or smells. Some examples of properties are shiny, hard, fragile, and stretchy.
For example, a shiny material reflects a lot of light. A fragile material breaks when you drop it. Flexible is a property. A flexible material can be bent without breaking easily.
Look at each picture, one at a time. Imagine bending the material shown in each picture.
Of the choices, the glass bowl is the most flexible. If you bend glass, it will not break. The answer is A.
Key Wrong Steps: A flexible material can be bent without breaking easily. Look at each picture, one at a time. Imagine bending the material shown in each picture. Of the choices, the glass bowl is the most flexible. If you bend glass, it will not break.
Missing Skill:

The missing skill in this query is the ability to understand and identify the actual properties of materials, specifically focusing on flexibility. The key wrong steps indicate a misunderstanding of flexibility, stating that the glass bowl is the most flexible because it will not break when bent. However, glass is actually a brittle material and would break if bent, making it less flexible than the other options. The correct answer is (C) metal hair clip, as metal is known to be a flexible material that can be bent without breaking easily.

Query: How long is a sofa?
Context: Select the best estimate.
Options: (A) 4 yards (B) 4 inches (C) 4 feet (D) 4 miles
Answer: The answer is C
Wrong Rationale: Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
When you are using customary units, length may be written with units of inches, feet, yards, or miles.
There are 12 inches in 1 foot, and 3 feet in 1 yard. There are 5,280 feet in 1 mile.
A football is about 1 foot long. A football field is 100 yards long. The best estimate for the length of a sofa is 4 yards.
4 inches and 4 feet are too short. 4 miles is too long. The answer is A.
Key Wrong Steps: There are 5,280 feet in 1 mile. A football is about 1 foot long. A football field is 100 yards long. The best estimate for the length of a sofa is 4 yards. 4 inches and 4 feet are too short.

Query: Which property do these four objects have in common?
Context: Select the best answer.
Options: (A) rough (B) flexible (C) opaque
Answer: The answer is C
Wrong Rationale: An object has different properties. A property of an object can tell you how it looks, feels, tastes, or smells. Properties can also tell you how an object will behave when something happens to it.
Different objects can have properties in common. You can use these properties to put objects into groups. Grouping objects by their properties is called classification. Look at each object.
For each object, decide if it has that property.
A flexible object can be folded or bent without breaking easily. All four objects are flexible.
An opaque object does not let light through. The hair clip is opaque, but the building blocks are not.
A rough object feels scratchy when you touch it. The building blocks are rough, but the hair clip is not.
The property that all four objects have in common is flexible. The answer is B.
Key Wrong Steps:
Missing Skill:

The missing skill in this scenario is the ability to correctly identify and understand the properties of objects and compare them to determine which property they have in common. The key wrong steps in the rationale include incorrectly identifying the property of flexibility for all four objects and incorrectly stating that the answer is B (flexible) instead of C (opaque). The missing skill, in this case, is the ability to accurately identify and compare properties of objects to determine which property they have in common.

Query: Which word would you find on a dictionary page with the following guide words?
beaver - bury
Context: N/A
Options: (A) banner (B) brier
Answer: The answer is B
Wrong Rationale: Guide words appear on each page of a dictionary. They tell you the first word and last word on the page. The other words on the page come between the guide words in alphabetical order.
To put words in alphabetical order, put them in order by their first letters. If the first letters are the same, look at the second letters. If the second letters are the same, look at the third letters, and so on. Put the words in alphabetical order.
Since banner is between the guide words beaver - bury, it would be found on that page. The answer is A.
Key Wrong Steps: If the first letters are the same, look at the second letters. If the second letters are the same, look at the third letters, and so on. Put the words in alphabetical order. Since banner is between the guide words beaver - bury, it would be found on that page. The answer is A.
Missing Skill:

The missing skill is understanding how guide words work in a dictionary. Guide words do not indicate all the words that appear between them in alphabetical order. Rather, they indicate the first word and last word on the page, and all the words on the page should fall between these two guide words in alphabetical order. Therefore, the word that appears on the page with the guide words "beaver - bury" should start with a letter between "beaver" and "bury".

Query: Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
Context: The images below show two pairs of magnets. The magnets in different pairs do not affect each other. All the magnets shown are made of the same material, but some of them are different shapes.
Options: (A) The magnitude of the magnetic force is the same in both pairs. (B) The magnitude of the magnetic force is greater in Pair 2. (C) The magnitude of the magnetic force is greater in Pair 1.
Answer: The answer is B
Wrong Rationale: Magnets can pull or push on each other without touching. When magnets attract, they pull together. When magnets repel, they push apart. These pulls and pushes between magnets are called magnetic forces.
The strength of a force is called its magnitude. The greater the magnitude of the magnetic force between two magnets, the more strongly the magnets attract or repel each other.
You can change the magnitude of a magnetic force between two magnets by changing the distance between them. The magnitude of the magnetic force is greater when there is a smaller distance between the magnets. Distance affects the magnitude of the magnetic force. When there is a smaller distance between magnets, the magnitude of the magnetic force between them is greater.
There is a smaller distance between the magnets in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is greater in Pair 1 than in Pair 2. The answer is C.
Key Wrong Steps: The magnitude of the magnetic force is greater when there is a smaller distance between the magnets. Distance affects the magnitude of the magnetic force. When there is a smaller distance between magnets, the magnitude of the magnetic force between them is greater. There is a smaller distance between the magnets in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is greater in Pair 1 than in Pair 2.
Missing Skill:

The missing skill in this case is understanding that the shape of the magnets can also affect the magnitude of the magnetic force. The wrong rationale assumes that the only factor affecting the magnitude of the force is the distance between the magnets. However, the shape of the magnets can also impact their magnetic field and the strength of the force. In this case, Pair 2 consists of magnets with a stronger magnetic field, resulting in a greater magnitude of the magnetic force compared to Pair 1.

Query: Which of the following contains a vague pronoun reference?
Context: N/A
Options: (A) I didn't like the ending of The Fault in Our Stars, but the book critic thought it was well-written. (B) The book critic thought The Fault in Our Stars was well-written, but I didn't like the ending.
Answer: The answer is A
Wrong Rationale: 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 it could refer to the book critic or the ending of the book.
The book critic thought The Fault in Our Stars was well-written, but I didn't like the ending.
The second answer choice shows a possible correction for the vague pronoun reference. The text has been rewritten so that the meaning is clear.
I didn't like the ending of The Fault in Our Stars, but the book critic thought it was well-written. The answer is B.
Key Wrong Steps: 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.

Options: (A) The magnitude of the magnetic force is the same in both pairs. (B) The magnitude of the magnetic force is greater in Pair 2. (C) The magnitude of the magnetic force is greater in Pair 1.
Answer: The answer is B
Wrong Rationale: Magnets can pull or push on each other without touching. When magnets attract, they pull together. When magnets repel, they push apart. These pulls and pushes between magnets are called magnetic forces.
The strength of a force is called its magnitude. The greater the magnitude of the magnetic force between two magnets, the more strongly the magnets attract or repel each other.
You can change the magnitude of a magnetic force between two magnets by changing the distance between them. The magnitude of the magnetic force is greater when there is a smaller distance between the magnets. The magnets in Pair 1 attract. The magnets in Pair 2 repel. But whether the magnets attract or repel affects only the direction of the magnetic force. It does not affect the magnitude of the magnetic force.
Distance affects the magnitude of the magnetic force. When there is a smaller distance between magnets, the magnitude of the magnetic force between them is greater.
There is a smaller distance between the magnets in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is greater in Pair 1 than in Pair 2. The answer is C.
Key Wrong Steps: The greater the magnitude of the magnetic force between two magnets, the more strongly the magnets attract or repel each other. You can change the magnitude of a magnetic force between two magnets by changing the distance between them.

Options: (A) The magnetic force is stronger in Pair 2. (B) The magnetic force is stronger in Pair 1. (C) The strength of the magnetic force is the same in both pairs.
Answer: The answer is B
Wrong Rationale: Magnets can pull or push on each other without touching. When magnets attract, they pull together. When magnets repel, they push apart.
These pulls and pushes between magnets are called magnetic forces. The stronger the magnetic force between two magnets, the more strongly the magnets attract or repel each other.
You can change the strength of a magnetic force between two magnets by changing the distance between them. The magnetic force is stronger when the magnets are closer together. Distance affects the strength of the magnetic force. When magnets are closer together, the magnetic force between them is stronger.
The magnets in Pair 2 are closer together than the magnets in Pair 1. So, the magnetic force is stronger in Pair 2 than in Pair 1. The answer is A.
Key Wrong Steps: The magnetic force is stronger when the magnets are closer together. Distance affects the strength of the magnetic force. When magnets are closer together, the magnetic force between them is stronger. The magnets in Pair 2 are closer together than the magnets in Pair 1. So, the magnetic force is stronger in Pair 2 than in Pair 1.

Context: The diagrams below show two pure samples of gas in identical closed, rigid containers. Each colored ball represents one gas particle. Both samples have the same number of particles.
Options: (A) sample A (B) neither; the samples have the same temperature (C) sample B
Answer: The answer is C
Wrong Rationale: The temperature of a substance depends on the average kinetic energy of the particles in the substance. The higher the average kinetic energy of the particles, the higher the temperature of the substance.
The kinetic energy of a particle is determined by its mass and speed. For a pure substance, the greater the mass of each particle in the substance and the higher the average speed of the particles, the higher their average kinetic energy. Each particle in the two samples has the same mass, but the particles in sample A have a higher average speed than the particles in sample B. So, the particles in sample A have a higher average kinetic energy than the particles in sample B.
Because the particles in sample A have the higher average kinetic energy, sample A must have the higher temperature. The answer is A.
Key Wrong Steps: The higher the average kinetic energy of the particles, the higher the temperature of the substance. The kinetic energy of a particle is determined by its mass and speed. For a pure substance, the greater the mass of each particle in the substance and the higher the average speed of the particles, the higher their average kinetic energy. Each particle in the two samples has the same mass, but the particles in sample A have a higher average speed than the particles in sample B. So, the particles in sample A have a higher average kinetic energy than the particles in sample B.
Missing Skill:

The missing skill in this query is analyzing the relationship between temperature and average kinetic energy of particles in a substance. The person incorrectly assumes that the substance with higher average kinetic energy has a higher temperature. However, the person fails to consider that temperature is a measure of the average kinetic energy of all the particles in the substance, not just one particle.

Demonstration: Which solution has a higher concentration of pink particles?
Context: The diagram below is a model of two solutions. Each pink ball represents one particle of solute.
Options: (A) Solution A (B) Solution B (C) neither; their concentrations are the same
Answer: The answer is A
Rationale: To determine which solution has a higher concentration of pink particles, we need to compare the number of pink particles in each solution. In the image, there are 40 pink particles in Solution A and 40 pink particles in Solution B. Since the number of particles is the same in both solutions, their concentrations are also the same. Therefore, the answer is (C) neither; their concentrations are the same.
Wrong Rationale Steps: In the image, there are 40 pink particles in Solution A and 40 pink particles in Solution B. Since the number of particles is the same in both solutions, their concentrations are also the same.
Missing Skill: The model did not accurately observe the number of pink particles in each flask as shown in the image.
Query: Which solution has a higher concentration of yellow particles?
Context: The diagram below is a model of two solutions. Each yellow ball represents one particle of solute.
Options: (A) Solution B (B) neither; their concentrations are the same (C) Solution A
Answer: The answer is B
Wrong Rationale: A solution is made up of two or more substances that are completely mixed. In a solution, solute particles are mixed into a solvent. The solute cannot be separated from the solvent by a filter. For example, if you stir a spoonful of salt into a cup of water, the salt will mix into the water to make a saltwater solution. In this case, the salt is the solute. The water is the solvent.
The concentration of a solute in a solution is a measure of the ratio of solute to solvent. Concentration can be described in terms of particles of solute per volume of solvent.
concentration = particles of solute / volume of solvent In Solution A and Solution B, the yellow particles represent the solute. To figure out which solution has a higher concentration of yellow particles, look at both the number of yellow particles and the volume of the solvent in each container.
Use the concentration formula to find the number of yellow particles per milliliter.
Solution A has more yellow particles per milliliter. So, Solution A has a higher concentration of yellow particles. The answer is C.
Key Wrong Steps: The water is the solvent. The concentration of a solute in a solution is a measure of the ratio of solute to solvent. Concentration can be described in terms of particles of solute per volume of solvent. concentration = particles of solute / volume of solvent In Solution A and Solution B, the yellow particles represent the solute. To figure out which solution has a higher concentration of yellow particles, look at both the number of yellow particles and the volume of the solvent in each container.
Missing Skill:

The missing skill in this case is understanding that concentration is determined by the ratio of solute to solvent, not just the number of particles.

Query: Is a juice pop a solid, a liquid, or a gas?
Context: N/A
Options: (A) a liquid (B) a solid (C) a gas
Answer: The answer is B
Wrong Rationale: Solid, liquid, and gas 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 definite volume and a definite shape. So, a solid has a size and shape of its own.
Some solids can be easily folded, bent, or broken. A piece of paper is a solid. Also, some solids are very small. A grain of sand is a solid.
When matter is a liquid, it has a definite volume but not a definite shape. So, a liquid has a size of its own, but it does not have a shape of its own. Think about pouring juice from a bottle into a cup. The juice still takes up the same amount of space, but it takes the shape of the bottle.
Some liquids do not pour as easily as others. Honey and milk are both liquids. But pouring honey takes more time than pouring milk.
When matter is a gas, it does not have a definite volume or a definite shape. A gas expands, or gets bigger, until it completely fills a space. A gas can also get smaller if it is squeezed into a smaller space.
Many gases are invisible. Air is a gas. A juice pop is a liquid. A liquid takes the shape of any container it is in.
If you squeeze a juice pop, it will take the shape of a bottle-shaped container. But the juice pop will still take up the same amount of space. The answer is A.
Key Wrong Steps: Air is a gas. A juice pop is a liquid. A liquid takes the shape of any container it is in. If you squeeze a juice pop, it will take the shape of a bottle-shaped container. But the juice pop will still take up the same amount of space.
Missing Skill:

The missing skill in this case is the ability to differentiate between different states of matter (solid, liquid, gas) and understand their characteristics. In the wrong rationale, there is confusion between the properties of liquids and solids, leading to the incorrect conclusion that a juice pop is a liquid. The correct understanding is that a juice pop is a solid because it has a definite shape and size, and it does not take the shape of the container it is in.

Query: Would you find the word long on a dictionary page with the following guide words?
level - lion
Context: N/A
Options: (A) yes (B) no
Answer: The answer is B
Wrong Rationale: Guide words appear on each page of a dictionary. They tell you the first word and last word on the page. The other words on the page come between the guide words in alphabetical order.
To put words in alphabetical order, put them in order by their first letters. If the first letters are the same, look at the second letters. If the second letters are the same, look at the third letters, and so on.
If one word is shorter, and there are no more letters to compare, then the shorter word comes first in alphabetical order. For example, be comes before bed. Put the words in alphabetical order.
Since long is between the guide words level - lion, it would be found on that page. The answer is A.
Key Wrong Steps: If one word is shorter, and there are no more letters to compare, then the shorter word comes first in alphabetical order. For example, be comes before bed. Put the words in alphabetical order. Since long is between the guide words level - lion, it would be found on that page. The answer is A.
Missing Skill:

The missing skill in this case is understanding how to determine the alphabetical order of words using guide words in a dictionary.

Query: Complete the text to describe the diagram.
Solute particles moved in both directions across the permeable membrane. But more solute particles moved across the membrane (). When there was an equal concentration on both sides, the particles reached equilibrium.
Context: The diagram below shows a solution with one solute. Each solute particle is represented by a pink ball. The solution fills a closed container that is divided in half by a membrane. The membrane, represented by a dotted line, is permeable to the solute particles.
The diagram shows how the solution can change over time during the process of diffusion.
Options: (A) to the right than to the left (B) to the left than to the right
Answer: The answer is B
Wrong Rationale: In a solution, solute particles move and spread throughout the solvent. The diagram below shows how a solution can change over time. Solute particles move from the area where they are at a higher concentration to the area where they are at a lower concentration. This movement happens through the process of diffusion.
As a result of diffusion, the concentration of solute particles becomes equal throughout the solution. When this happens, the solute particles reach equilibrium. At equilibrium, the solute particles do not stop moving. But their concentration throughout the solution stays the same.
Membranes, or thin boundaries, can divide solutions into parts. A membrane is permeable to a solute when particles of the solute can pass through gaps in the membrane. In this case, solute particles can move freely across the membrane from one side to the other.
So, for the solute particles to reach equilibrium, more particles will move across a permeable membrane from the side with a higher concentration of solute particles to the side with a lower concentration. At equilibrium, the concentration on both sides of the membrane is equal. Look at the diagram again. It shows you how the solution changed during the process of diffusion.
Before the solute particles reached equilibrium, there were 5 solute particles on the left side of the membrane and 3 solute particles on the right side of the membrane.
When the solute particles reached equilibrium, there were 4 solute particles on each side of the membrane. There was 1 more solute particle on the right side of the membrane than before.
So, for the solute particles to reach equilibrium, more solute particles must have moved across the membrane to the right than to the left. The answer is A.
Key Wrong Steps: Before the solute particles reached equilibrium, there were 5 solute particles on the left side of the membrane and 3 solute particles on the right side of the membrane. When the solute particles reached equilibrium, there were 4 solute particles on each side of the membrane. There was 1 more solute particle on the right side of the membrane than before. So, for the solute particles to reach equilibrium, more solute particles must have moved across the membrane to the right than to the left. The answer is A.

Query: Complete the sentence.
A firework exploding is a ().
Context: N/A
Options: (A) chemical change (B) physical change
Answer: The answer is A
Wrong Rationale: 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. A firework exploding is a change of state. So, it is a physical change. The firework breaks into pieces of itself. They are still made of the same type of matter. The answer is B.
Key Wrong Steps: 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. A firework exploding is a change of state. So, it is a physical change.
Missing Skill:

The missing skill is the ability to recognize that a firework exploding is a chemical change, not a physical change.

Ozone is ().
Context: The model below represents a molecule of ozone. zone gas in the atmosphere protects living things on Earth from some of the Sun's harmful rays.
Options: (A) a compound (B) an elementary substance
Answer: The answer is B
Wrong Rationale: 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 boron is B, and the atomic symbol for the chemical element chlorine is Cl.
Scientists use different types of models to represent substances whose atoms are bonded in different ways. One type of model is a ball-and-stick model. The ball-and-stick model below represents a molecule of the compound boron trichloride.
In a ball-and-stick model, the balls represent atoms, and the sticks represent bonds. Notice that the balls in the model above are not all the same color. Each color represents a different chemical element. The legend shows the color and the atomic symbol for each chemical element in the substance. Use the model to determine whether ozone is an elementary substance or a compound.
Step 1: Interpret the model.
.
Use the legend to determine the chemical element represented by each color. The colors and atomic symbols from the legend are shown in the table below. The table also includes the names of the chemical elements represented in the model.
You can see from the model that a molecule of ozone is composed of three oxygen atoms bonded together.
Step 2: Determine whether the substance is an elementary substance or a compound.
You know from Step 1 that ozone is composed of two chemical elements: oxygen and a special element that is not found in nature. This special element is represented by the color red in the model. So, ozone is composed of two chemical elements bonded together.
Substances that are composed of multiple chemical elements bonded together are compounds. So, ozone is a compound. The answer is A.
Key Wrong Steps: The legend shows the color and the atomic symbol for each chemical element in the substance. Use the model to determine whether ozone is an elementary substance or a compound. Step 1: Interpret the model. . Use the legend to determine the chemical element represented by each color.
Missing Skill:

The missing skill in this scenario is interpreting the information provided by the legend in order to determine the chemical elements represented in the model.
