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

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

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: B

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: The particles in both samples have the same average speed, but each particle in sample A has more mass than each particle 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 C.

question: Which word would you find on a dictionary page with the following guide words? shy - spool

choice: (A) symbol (B) slippery

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 symbol is between the guide words shy - spool, it would be found on that page.
10: The answer is A.

question: Which type of relationship is formed when a megabat eats a fig and drops the fig tree's seeds in a new location?

choice: (A) parasitic (B) mutualistic (C) commensal

context: Read the passage. Then answer the question. Megabats are large-bodied bats that eat fruit, including figs. When a megabat eats a fig, it may also swallow the seeds inside the fig. The bat gets energy from the fruit but cannot digest the seeds. The seeds pass through the bat's digestive system and are disposed of in its feces. The bat often drops the seeds far from the fig tree that produced the fruit. When a seed germinates, or begins to grow, in a new location, it doesn't need to compete with its parent tree for resources. So, both the fig seed and the parent tree have a better chance of surviving. Figure: a megabat carrying a fig away from a fig tree.

gold answer: B

wrong prediction:

Rationale:

0: When two organisms of different species interact in a way that affects one or both organisms, they form a symbiotic relationship.
1: The word symbiosis comes from a Greek word that means living together.
2: Scientists define types of symbiotic relationships based on how each organism is affected.
3: This table lists three common types of symbiotic relationships.
4: It shows how each organism is affected in each type of symbiotic relationship.
5: Type of symbiotic relationship | Organism of one species... | Organism of the other species... Commensal | benefits | is not significantly affected Mutualistic | benefits | benefits Parasitic | benefits | is harmed (but not usually killed) When a megabat eats a fig and drops the fig tree's seeds in a new location, the bat gets energy from the fruit but cannot digest the seeds.
6: So, the bat benefits from its interaction with the fig tree, but the tree is harmed.
7: Since the bat benefits and the tree is harmed, a commensal relationship is formed when a megabat eats a fig and drops the fig tree's seeds in a new location.
8: The answer is C.

question: Which word would you find on a dictionary page with the following guide words? slush - star

choice: (A) seventh (B) spray

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 seventh is between the guide words slush - star, it would be found on that page.
10: The answer is A.

question: Which of these states is farthest west?

choice: (A) Michigan (B) Arkansas (C) Alabama (D) North Dakota

gold answer: D

wrong prediction:

Rationale:

0: Maps have four cardinal directions, or main directions.
1: Those directions are north, south, east, and west.
2: A compass rose is a set of arrows that point to the cardinal directions.
3: A compass rose usually shows only the first letter of each cardinal direction.
4: The north arrow points to the North Pole.
5: On most maps, north is at the top of the map.
6: To find the answer, look at the compass rose.
7: Look at which way the west arrow is pointing.
8: Arkansas is farthest west.
9: The answer is B.

question: Which of the following fossils is younger? Select the more likely answer.

choice: (A) wood (B) mammal tooth

context: This diagram shows fossils in an undisturbed sedimentary rock sequence.

gold answer: B

wrong prediction:

Rationale:

0: A fossil is the preserved evidence of an ancient organism.
1: Some fossils are formed from body parts such as bones or shells.
2: Other fossils, such as footprints or burrows, are formed from traces of an organism's activities.
3: Fossils are typically found in sedimentary rocks.
4: Sedimentary rocks usually form in layers.
5: Over time, new layers are added on top of old layers in a series called a rock sequence.
6: The layers in an undisturbed rock sequence are in the same order as when they formed.
7: So, the deeper layers are older than the shallower layers.
8: The relative ages of fossils can be determined from their positions in an undisturbed rock sequence.
9: Older fossils are usually in deeper layers, and younger fossils are usually in shallower layers.
10: Look again at the fossils in the rock sequence diagram.
11: Compare the positions of these fossils to determine which one is younger: The wood fossil is in a shallower layer in the rock sequence than the mammal tooth fossil.
12: So, the wood fossil is most likely younger than the mammal tooth fossil.
13: The answer is A.

question: In this food web, which organism contains matter that eventually moves to the bat star?

choice: (A) kelp (B) sea otter (C) orca

context: Below is a food web from an ocean ecosystem in Monterey Bay, off the coast of California. 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.

gold answer: A

wrong prediction:

Rationale:

0: A food web is a model.
1: A food web shows where organisms in an ecosystem get their food.
2: Models can make things in nature easier to understand because models can represent complex things in a simpler way.
3: If a food web showed every organism in an ecosystem, the food web would be hard to understand.
4: So, each food web shows how some organisms in an ecosystem can get their food.
5: Arrows show how matter moves.
6: A food web has arrows that point from one organism to another.
7: Each arrow shows the direction that matter moves when one organism eats another organism.
8: An arrow starts from the organism that is eaten.
9: The arrow points to the organism that is doing the eating.
10: An organism in a food web can have more than one arrow pointing from it.
11: This shows that the organism is eaten by more than one other organism in the food web.
12: An organism in a food web can also have more than one arrow pointing to it.
13: This shows that the organism eats more than one other organism in the food web.
14: Use the arrows to follow how matter moves through this food web.
15: For each answer choice, try to find a path of arrows to the bat star.
16: The only arrow pointing from the sea otter leads to the orca.
17: The only arrow pointing from the orca leads to the killer whale.
18: No arrows point from the killer whale to any other organisms.
19: So, in this food web, matter does not move from the sea otter to the bat star.
20: The only arrow pointing from the kelp leads to the sea urchin.
21: The only arrow pointing from the sea urchin leads to the sea otter.
22: No arrows point from the sea otter to any other organisms.
23: So, in this food web, matter does not move from the kelp to the bat star.The only arrow pointing from the zooplankton leads to the plainfin midshipman.
24: The only arrow pointing from the plainfin midshipman leads to the zooplankton.
25: No arrows point from the zooplankton to any other organisms.
26: So, in this food web, matter does not move from the zooplankton to the bat star.
27: The answer is C.

question: Which animal is also adapted to be camouflaged in a sandy desert?

choice: (A) kingsnake (B) horned viper

context: Camels live in dry places such as deserts. The is adapted to be camouflaged in a sandy desert. Figure: camel.

gold answer: B

wrong prediction:

Rationale:

0: An adaptation is an inherited trait that helps an organism survive or reproduce.
1: Adaptations can include both body parts and behaviors.
2: The color, texture, and covering of an animal's skin are examples of adaptations.
3: Animals' skins can be adapted in different ways.
4: For example, skin with thick fur might help an animal stay warm.
5: Skin with sharp spines might help an animal defend itself against predators.
6: Look at the picture of the camel.
7: The camel has sand-colored fur covering its skin.
8: It is adapted to be camouflaged in a sandy desert.
9: The word camouflage means to blend in.
10: Now look at each animal.
11: Figure out which animal has a similar adaptation.
12: The kingsnake has sand-colored scales covering its body.
13: It is adapted to be camouflaged in a sandy desert.
14: The horned viper has a dark, bumpy body.
15: It is not adapted to be camouflaged in a sandy desert.
16: The answer is A.
