Answers and Explanations

1) D

In paragraph 1, we learn that “fleas are ideally equipped to do what they do, making them very difficult to defeat.” In paragraph 2 the

author explains why fleas are hard to squish and why they resist so many sprays designed to kill them. In paragraphs 3-6, the

author explains what makes fleas so difficult to get rid of, both in terms of their physical characteristics and the way they reproduce.

In the last paragraph, the author calls fleas “intimidating opponents” and suggests that preventing an infestation is easier that getting

rid of an infestation. From this we can understand that the primary purpose of the passage is to explain why a flea infestation is hard

to get rid of. Therefore (D) is correct. The passage does provide information about the physical characteristics of fleas, but it also

educates readers about the life cycle and reproduction process of a flea. Furthermore, these details all support the author’s main

point, which is that a flea infestation is very hard to get rid of. Because it is too narrow in scope, (A) is incorrect. In paragraph 1, the

author briefly compares a flea to “a shark in the water or a wolf in the woods.” Later the author says that fleas “are some of the best

jumpers in the natural world.” However, the author does not expand on these comments; rather, the author describes in detail why a

flea infestation is hard to get rid of. Because the comparisons are only minor details in the passage, (B) is incorrect. The passage

does not contain any information about the problems that can result from a flea infestation, so (C) is incorrect.

2) C

The author presents facts about the characteristics of fleas without expressing any emotions or opinions in the passage. Since the

author’s main purpose is to present information, we can conclude that the tone is informative. Therefore (C) is correct. Concerned

means worried or anxious. The author does not express any anxiety about fleas, so (A) is incorrect. Passionate means caused by

strong feelings. Since the author does not express emotions in the passage, (B) is incorrect. Opinionated means certain of one’s

opinions or stubborn. The author is presenting facts, not opinions, so (D) is incorrect.

3) A

In paragraph 2, we learn that “a flea has a very hard exoskeleton, which means the body is covered by a tough, tile-like plate called

a sclerite.” From this we can understand that, on a flea, a sclerite forms the exoskeleton. Later in paragraph 2, the author says that

“the exoskeletons of fleas are also waterproof and shock resistant, and therefore fleas are highly resistant to the sprays and

chemicals used to kill them.” Since we know that the exoskeleton on a flea is called a sclerite, we can infer that the sclerite is

waterproof, which makes fleas resistant to sprays and chemicals. Therefore (A) is correct. The other answer choices are all

characteristics of fleas mentioned in the passage, but none of them make fleas resistant to chemicals. Therefore (B), (C), and (D)

are incorrect.

4) A

In paragraph 2, we learn that “a flea has a very hard exoskeleton, which means the body is covered by a tough, tile-like plate called

a sclerite. Because of these plates, fleas are almost impossible to squish.” From this we can understand that the sclerite makes a

flea difficult to squish. This supports option (I). In paragraph 3, we learn that fleas do have spines attached to the sclerite, but these

spines make a flea difficult to pull off, not difficult to squish. This eliminates option (II). In paragraph 5, we learn that fleas have a

protein in their joints called resilin, “which helps catapult fleas into the air as they jump.” From this we can understand that resilin

helps fleas jump, but it does not make them difficult to squish. This eliminates option (III). Therefore (A) is correct.

5) A

In paragraph 3, we learn that fleas have little spines that normally lie flat, but “if anything (like fingers or a self-grooming pet) tries to
