question: Which is a simple sentence?

choice: (A) In June, Erin and Preston will graduate with honors from Burlington High School. (B) When the supervisor arrived at the quarry, six dump trucks were in line at the gate.

gold answer: A

wrong prediction:

Rationale:

0: A simple sentence is a sentence with only one subject and predicate.
1: The pitcher threw the ball to first base.
2: A compound sentence is two simple sentences joined by a comma and a conjunction such as and, but, or, or so.
3: The pitcher threw the ball, and the batter hit it.
4: Some simple sentences have a compound subject or a compound predicate, but they are not compound sentences.
5: Anna and James will watch the fireworks tonight.
6: This simple sentence has a compound subject, Anna and James.
7: The singers bowed and walked off the stage.
8: This simple sentence has a compound predicate, bowed and walked off the stage.
9: Some simple sentences have introductory phrases, but they are not compound sentences.
10: The introductory phrase is part of the predicate.
11: In the winter, Farmer Ben wears his heavy coat.
12: This is a simple sentence.
13: There is one subject, Farmer Ben, and one predicate, wears his heavy coat in the winter.
14: The second sentence is the simple sentence.
15: It has one subject and predicate.

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 greater in Pair 2. (B) The magnitude of the magnetic force is the same in both pairs. (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, but some of them are different sizes and shapes.

gold answer: C

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 using magnets of different sizes.
7: The magnitude of the magnetic force is greater when the magnets are larger.
8: The magnets in Pair 2 attract.
9: The magnets in Pair 1 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: Magnet sizes affect the magnitude of the magnetic force.
13: Imagine magnets that are the same shape and made of the same material.
14: The larger the magnets, the greater the magnitude of the magnetic force between them.
15: Magnet A is the same size in both pairs.
16: But Magnet B is larger in Pair 2 than in Pair 1.
17: So, the magnitude of the magnetic force is greater in Pair 2 than in Pair 1.
18: The answer is A.

question: Based on this information, what is Jupiter's genotype for the coat pattern gene?

choice: (A) aa (B) a black coat

context: In a group of leopards, some individuals have a spotted coat and others have a black coat. In this group, the gene for the coat pattern trait has two alleles. The allele A is for a spotted coat, and the allele a is for a black coat. Jupiter, a leopard from this group, has a black coat. Jupiter has two alleles for a black coat.

gold answer: A

wrong prediction:

Rationale:

0: All organisms have pieces of hereditary material called genes, which are passed from parents to offspring.
1: Genes contain instructions for building the parts of an organism.
2: An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have.
3: Genes may have different alleles, or forms, that can cause different versions of a trait.
4: For example, flower color is a trait in pea plants.
5: The gene for this trait has two possible alleles.
6: Each allele is represented by an uppercase or lowercase letter.
7: The allele F is for purple flowers, and the allele f is for white flowers.
8: Each pea plant has two alleles for the flower color gene—one allele inherited from each parent.
9: An organism's genotype for a gene is its combination of alleles for that gene.
10: So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene.
11: An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles.
12: A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait.
13: An organism's genotype for a gene is its combination of alleles for that gene.
14: Jupiter has two alleles for a black coat (a).
15: So, Jupiter's genotype for the coat pattern gene is a black coat.
16: The answer is B.

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: Magnet sizes affect the magnitude of the magnetic force.
13: Imagine magnets that are the same shape and made of the same material.
14: The larger the magnets, the greater the magnitude of the magnetic force between them.

question: Will these magnets attract or repel each other?

choice: (A) repel (B) attract

context: Two magnets are placed as shown. Hint: Magnets that attract pull together. Magnets that repel push apart.

gold answer: A

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: Whether a magnet attracts or repels other magnets depends on the positions of its poles, or ends.
4: Every magnet has two poles, called north and south.
5: Here are some examples of magnets.
6: The north pole of each magnet is marked N, and the south pole is marked S. If different poles are closest to each other, the magnets attract.
7: The magnets in the pair below attract.
8: If the same poles are closest to each other, the magnets repel.
9: The magnets in both pairs below repel.
10: Will these magnets attract or repel?
11: To find out, look at which poles are closest to each other.
12: The north pole of one magnet is closest to the south pole of the other magnet.
13: Poles that are different attract.
14: So, these magnets will attract each other.
15: The answer is B.

question: Which of the following organisms is the omnivore in this food web?

choice: (A) plainfin midshipman (B) sea urchin (C) phytoplankton (D) kelp

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: Omnivores are consumers that eat both producers and other consumers.
15: So, an omnivore has arrows pointing to it from at least one producer and at least one consumer.
16: The kelp has arrows pointing to it from the phytoplankton and the sea urchin.
17: The phytoplankton is a producer, and the sea urchin is a consumer.
18: So, the kelp has arrows pointing to it from both a producer and a consumer.
19: The kelp also has an arrow pointing to it from the orca.
20: But that arrow starts from the zooplankton, which is not a producer.
21: So, the kelp does not have the arrows it needs to be an omnivore.
22: The sea urchin has an arrow pointing to it from the kelp.
23: The kelp is a producer, so the sea urchin has an arrow pointing to it from a producer.
24: The sea urchin also has an arrow pointing to it from the plainfin midshipman.
25: The plainfin midshipman is a consumer, so the sea urchin has an arrow pointing to it from both a producer and a consumer.
26: The sea urchin has the arrows it needs to be an omnivore.
27: The phytoplankton does not have any arrows pointing to it.
28: So, the phytoplankton is not an omnivore.
29: The plainfin midshipman has an arrow pointing to it from the zooplankton.
30: The zooplankton is not a producer, so the plainfin midshipman does not have the arrows it needs to be an omnivore.
31: The answer is B.

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: Distance affects the magnitude of the magnetic force.
9: When there is a smaller distance between magnets, the magnitude of the magnetic force between them is greater.
10: There is a smaller distance between the magnets in Pair 2 than in Pair 1.
11: So, the magnitude of the magnetic force is greater in Pair 2 than in Pair 1.
12: The answer is A.

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

choice: (A) cure (B) chore

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 cure is between the guide words car - coupon, it would be found on that page.
10: The answer is A.

choice: (A) Wendy remembers her parents. (B) Peter defeats Captain Hook.

context: This event chain shows events from Peter and Wendy by J. M. Barrie.

gold answer: A

wrong prediction:

Rationale:

0: A graphic organizer is a chart or picture that shows how ideas, facts, or topics are related to one another.
1: When you read, look for graphic organizers included in the text.
2: You can use these images to find key information.
3: You can also create your own graphic organizers with information that you've read.
4: Doing this can help you think about the ideas in the text and easily review them.
5: When you write, you can use graphic organizers to organize your thoughts and plan your writing.
6: An event chain uses arrows to show the order of events.
7: This event chain shows events from Peter and Wendy by J. M. Barrie.
8: Follow the arrows to see the order of events.
9: An arrow points from The battle at Mermaids' Lagoon to Peter defeats Captain Hook.
10: This tells you that Peter defeats Captain Hook happens right after the battle at Mermaids' Lagoon.
11: The answer is B.
