PSAT Reading Question 588: Answer and Explanation

Question: 588

What is the primary function of the sentence in lines 29–30 ("Both categories . . . disadvantages")?

• A. To define a couple of major concepts
• B. To give examples in support of a claim
• C. To provide a transition to the following paragraph
• D. To state the thesis of the essay

Correct Answer: C

Explanation:

(C) Lines 29–30 mention "both categories of drugs," and the next paragraph then goes on to describe both categories. Thus, these lines serve to "provide a transition to the following paragraph." Choice (A) is flawed in that the lines do not "define a couple of major concepts" but, rather, only refer to them. In choice (B), no specific supporting examples are provided. In choice (D), these lines, although important, do not contain the thesis (main idea) of the passage.
