PSAT Writing and Language Question 377: Answer and Explanation

Question: 377

• A. NO CHANGE
• B. instructors who would train Bessie
• C. instructors who would train Bessie,
• D. instructors, who would train Bessie

Correct Answer: B

Explanation:

B

Commas are changing in the answer choices, so this question is testing the four ways to use a comma. Commas change around the phrase who would train Bessie, so determine if the phrase is necessary. The phrase is necessary information, since it explains why the instructors were important, so it should not have commas around it. Choices (A), (C), and (D) all include commas, so eliminate them. The correct answer is (B).
