PSAT Writing and Language Question 113: Answer and Explanation

Question: 113

• A. NO CHANGE
• B. any of them
• C. themselves
• D. the female whales

Correct Answer: D

Explanation:

D

Pronouns and nouns change in the answer choices, so this question tests precision. A pronoun can only be used if it is clear what the pronoun refers to. Scientists are not the ones whom evolution has determined should live so much longer, so a pronoun is imprecise; eliminate (A), (B), and (C). Only (D) makes it clear that the female whales are the ones who live so much longer. The correct answer is (D).
