PASSAGE

The reaction proceeds _____ slowly at room temperature.

Which choice completes the text with the most logical and precise word or phrase?

A. instantly
B. extremely
C. impossibly
D. relatively✓ Correct

Detailed Answer Explanation

Choice D is the best answer. "Relatively" is correct because it means "in comparison with something else." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: A ("Instantly" means "at once," which doesn't fit the context.), B ("Extremely" means "to a very great degree," which doesn't fit the context.), C ("Impossibly" means "in a way that cannot occur," which doesn't fit the context.).
