question: Would you find the word amazed on a dictionary page with the following guide words? aboard - arrive

choice: (A) no (B) yes

gold answer: B

wrong prediction:

Rationale:

0: Guide words appear on each page of a dictionary.
1: They tell you the first word and last word on the page.
2: The other words on the page come between the guide words in alphabetical order.
3: To put words in alphabetical order, put them in order by their first letters.
4: If the first letters are the same, look at the second letters.
5: If the second letters are the same, look at the third letters, and so on.
6: If one word is shorter, and there are no more letters to compare, then the shorter word comes first in alphabetical order.
7: For example, be comes before bed.
8: Put the words in alphabetical order.
9: Since amazed is not between the guide words aboard - arrive, it would not be found on that page.
10: The answer is A.

question: Why might covering its eggs with its body increase the reproductive success of a snail leech? Complete the claim below that answers this question and is best supported by the passage. Covering its eggs with its body increases the chances that ().

choice: (A) the leech's eggs will hatch (B) the leech will not eat for up to a week (C) the leech will fight a water snail

context: Animals often behave in certain ways that can increase their reproductive success. Read the passage about a specific animal behavior. Then, follow the instructions below. The snail leech is a type of worm that often lives in freshwater streams. After reproduces, it attaches its eggs to a rock at the bottom of the stream. The leech then flattens its body over its eggs to protect them. The leech protects its eggs until they hatch, which takes four to seven days. During this time, the leech does not leave the eggs or eat. Water snails are predators that eat leech eggs. The snails easily eat eggs that are not covered by an adult leech. But snails cannot easily get to eggs that are covered by a leech. Figure: a snail leech.

gold answer: A

wrong prediction:

Rationale:

0: Animals increase their reproductive success when they have offspring that survive to reproduce.
1: Animals can increase their chances of having offspring by behaving in ways that help them get partners to mate and reproduce with.
2: These partners are called mates.
3: For example, animals may make special sounds, perform specific dances, or show off bright colors to attract mates.
4: Animals may also compete with each other for mates.
5: Animals can increase the chances that their offspring will survive to reproduce by caring for and protecting them.
6: For example, animals may feed their offspring or guard them from predators.
7: These behaviors increase the chances that the offspring will survive to adulthood, when they can reproduce.
8: Many behaviors can increase the chances that animals will have offspring that survive to reproduce.
9: But the behaviors cannot guarantee that the animals will have greater reproductive success.
10: Animals that attract or compete for mates won't always successfully mate and reproduce, and offspring that are fed and protected won't always survive to adulthood.
11: Look for the part of the passage that describes the effect of covering the eggs with the body.
12: Use this information to determine why this behavior can increase the reproductive success of the snail leech.
13: Choice "The snail leech is a type of worm that often lives in freshwater streams.
14: After reproduces, it attaches its eggs to a rock at the bottom of the stream.
15: The leech then flattens its body over its eggs to protect them.
16: The leech protects its eggs until they hatch, which takes four to seven days.
17: During this time, the leech does not leave the eggs or eat."
18: is incorrect.
19: Choice "Choice "Covering its eggs with its body increases the chances that the leech will fight a water snail."
20: is incorrect."
21: is correct.
22: Choice "According to the underlined text, predators can easily eat eggs that are not covered by an adult leech.
23: So, by covering its eggs with its body, the snail leech decreases the chances that its eggs will be eaten by predators.
24: This increases the chances that the snail leech will have offspring that survive to reproduce, which can increase its reproductive success."
25: is incorrect.
26: Choice "Choice "Covering its eggs with its body increases the chances that the leech's eggs will hatch."
27: is incorrect."
28: is incorrect.
29: Choice "Hatching the eggs does increase the chances that the snail leech will have offspring.
30: But hatching the eggs is not the same as increasing the snail leech's reproductive success.
31: Offspring that hatch can die, and they do not necessarily reproduce.
32: So, hatching the eggs does not necessarily increase the snail leech's reproductive success."
33: is incorrect.
34: Choice "Choice "Covering its eggs with its body increases the chances that the leech will not eat for up to a week."
35: is incorrect."
36: is incorrect.
37: Choice "Eating after attaching its eggs to a rock does not increase the snail leech's chances of producing offspring that survive to reproduce.
38: So, eating after attaching its eggs to a rock does not increase the snail leech's reproductive success."
39: is incorrect.
40: The answer is C.

question: Think about the magnetic force between the magnets in each pair. Which of the following statements is true?

choice: (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.

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.

gold answer: B

wrong prediction:

Rationale:

0: Magnets can pull or push on each other without touching.
1: When magnets attract, they pull together.
2: When magnets repel, they push apart.
3: These pulls and pushes between magnets are called magnetic forces.
4: The strength of a force is called its magnitude.
5: The greater the magnitude of the magnetic force between two magnets, the more strongly the magnets attract or repel each other.
6: You can change the magnitude of a magnetic force between two magnets by changing the distance between them.
7: The magnitude of the magnetic force is greater when there is a smaller distance between the magnets.
8: The magnets in Pair 1 attract.
9: The magnets in Pair 2 repel.
10: But whether the magnets attract or repel affects only the direction of the magnetic force.
11: It does not affect the magnitude of the magnetic force.
12: Distance affects the magnitude of the magnetic force.
13: When there is a smaller distance between magnets, the magnitude of the magnetic force between them is greater.
14: There is a smaller distance between the magnets in Pair 1 than in Pair 2.
15: So, the magnitude of the magnetic force is greater in Pair 1 than in Pair 2.
16: The answer is C.

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.

gold answer: B

wrong prediction:

Rationale:

0: Magnets can pull or push on each other without touching.
1: When magnets attract, they pull together.
2: When magnets repel, they push apart.
3: These pulls and pushes between magnets are called magnetic forces.
4: The stronger the magnetic force between two magnets, the more strongly the magnets attract or repel each other.
5: You can change the strength of a magnetic force between two magnets by changing the distance between them.
6: The magnetic force is stronger when the magnets are closer together.
7: Distance affects the strength of the magnetic force.
8: When magnets are closer together, the magnetic force between them is stronger.
9: The magnets in Pair 2 are closer together than the magnets in Pair 1.
10: So, the magnetic force is stronger in Pair 2 than in Pair 1.
11: The answer is A.

question: Compare the average kinetic energies of the particles in each sample. Which sample has the higher temperature?

choice: (A) sample A (B) neither; the samples have the same temperature (C) sample B

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.

gold answer: C

wrong prediction:

Rationale:

0: The temperature of a substance depends on the average kinetic energy of the particles in the substance.
1: The higher the average kinetic energy of the particles, the higher the temperature of the substance.
2: The kinetic energy of a particle is determined by its mass and speed.
3: 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.
4: 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.
5: So, the particles in sample A have a higher average kinetic energy than the particles in sample B.
6: Because the particles in sample A have the higher average kinetic energy, sample A must have the higher temperature.
7: The answer is A.

question: Which solution has a higher concentration of yellow particles?

choice: (A) Solution B (B) neither; their concentrations are the same (C) Solution A

context: The diagram below is a model of two solutions. Each yellow ball represents one particle of solute.

gold answer: B

wrong prediction:

Rationale:

0: A solution is made up of two or more substances that are completely mixed.
1: In a solution, solute particles are mixed into a solvent.
2: The solute cannot be separated from the solvent by a filter.
3: 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.
4: In this case, the salt is the solute.
5: The water is the solvent.
6: The concentration of a solute in a solution is a measure of the ratio of solute to solvent.
7: Concentration can be described in terms of particles of solute per volume of solvent.
8: concentration = particles of solute / volume of solvent In Solution A and Solution B, the yellow particles represent the solute.
9: 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.
10: Use the concentration formula to find the number of yellow particles per milliliter.
11: Solution A has more yellow particles per milliliter.
12: So, Solution A has a higher concentration of yellow particles.
13: The answer is C.

question: Is a juice pop a solid, a liquid, or a gas?

choice: (A) a liquid (B) a solid (C) a gas

gold answer: B

wrong prediction:

Rationale:

0: Solid, liquid, and gas are states of matter.
1: Matter is anything that takes up space.
2: Matter can come in different states, or forms.
3: When matter is a solid, it has a definite volume and a definite shape.
4: So, a solid has a size and shape of its own.
5: Some solids can be easily folded, bent, or broken.
6: A piece of paper is a solid.
7: Also, some solids are very small.
8: A grain of sand is a solid.
9: When matter is a liquid, it has a definite volume but not a definite shape.
10: So, a liquid has a size of its own, but it does not have a shape of its own.
11: Think about pouring juice from a bottle into a cup.
12: The juice still takes up the same amount of space, but it takes the shape of the bottle.
13: Some liquids do not pour as easily as others.
14: Honey and milk are both liquids.
15: But pouring honey takes more time than pouring milk.
16: When matter is a gas, it does not have a definite volume or a definite shape.
17: A gas expands, or gets bigger, until it completely fills a space.
18: A gas can also get smaller if it is squeezed into a smaller space.
19: Many gases are invisible.
20: Air is a gas.
21: A juice pop is a liquid.
22: A liquid takes the shape of any container it is in.
23: If you squeeze a juice pop, it will take the shape of a bottle-shaped container.
24: But the juice pop will still take up the same amount of space.
25: The answer is A.

3: To put words in alphabetical order, put them in order by their first letters.
4: If the first letters are the same, look at the second letters.
5: If the second letters are the same, look at the third letters, and so on.
6: If one word is shorter, and there are no more letters to compare, then the shorter word comes first in alphabetical order.
7: For example, be comes before bed.
8: Put the words in alphabetical order.
9: Since long is between the guide words level - lion, it would be found on that page.
10: The answer is A.

question: 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.

choice: (A) to the right than to the left (B) to the left than to the right

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.

gold answer: B

wrong prediction:

Rationale:

0: In a solution, solute particles move and spread throughout the solvent.
1: The diagram below shows how a solution can change over time.
2: Solute particles move from the area where they are at a higher concentration to the area where they are at a lower concentration.
3: This movement happens through the process of diffusion.
4: As a result of diffusion, the concentration of solute particles becomes equal throughout the solution.
5: When this happens, the solute particles reach equilibrium.
6: At equilibrium, the solute particles do not stop moving.
7: But their concentration throughout the solution stays the same.
8: Membranes, or thin boundaries, can divide solutions into parts.
9: A membrane is permeable to a solute when particles of the solute can pass through gaps in the membrane.
10: In this case, solute particles can move freely across the membrane from one side to the other.
11: 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.
12: At equilibrium, the concentration on both sides of the membrane is equal.
13: Look at the diagram again.
14: It shows you how the solution changed during the process of diffusion.
15: 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.
16: When the solute particles reached equilibrium, there were 4 solute particles on each side of the membrane.
17: There was 1 more solute particle on the right side of the membrane than before.
18: So, for the solute particles to reach equilibrium, more solute particles must have moved across the membrane to the right than to the left.
19: The answer is A.
