PSAT Reading Question 549: Answer and Explanation

Question: 549

As it is used in line 31, "evolving" most nearly means

• A. advancing.
• B. reproducing.
• C. selecting.
• D. generating.

Correct Answer: D

Explanation:

(D) "Evolving" is used to describe the process by which molecules gradually give off heat in the microwave, so "generating" best captures this meaning. Although the other options do give possible definitions of "evolving," they do not reflect the process of giving off heat.
