PSAT Writing and Language Question 3: Answer and Explanation

Question: 3

• A. NO CHANGE
• B. 1990s, for instance those
• C. 1990s, for instance, those
• D. 1990s for instance those

Correct Answer: C

Explanation:

Commas change in the answer choices, so this question tests the four ways to use a comma. The phrase for instance is unnecessary information, so it should have commas both before and after it. Choice (C) appropriately places commas both before and after the unnecessary phrase. Eliminate (B) because it lacks a comma after the phrase, and eliminate (D) because it lacks a comma before the phrase. There is no need for a comma after those, so eliminate (A). The correct answer is (C).
