PSAT Writing and Language Question 115: Answer and Explanation

Question: 115

• A. NO CHANGE
• B. scientists observed that many of the teaching behaviors were performed by whale grandmothers.
• C. whale grandmothers were the most likely to exhibit teaching behaviors.
• D. teaching behaviors were observed from whale grandmothers that were shown to scientists.

Correct Answer: B

Explanation:

B

Word order changes in the answer choices, so this question tests precision. Look for the phrase that makes the meaning of the sentence clear. The first part of the sentence says After watching over 750 hours of video and observing the behaviors of pods of whales. The first word after this phrase should indicate who did the watching and observing. The whale grandmothers are not the ones watching and observing, so eliminate (A) and (C). Keep (B) because it makes sense that the scientists are watching and observing. Eliminate (D) because teaching behaviors cannot watch and observe. The correct answer is (B).
