Answer: D

PASSAGE

The compound's therapeutic potential is _____ constrained by its poor bioavailability.

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

A. barely
B. accidentally
C. never
D. significantly✓ Correct

Detailed Answer Explanation

Choice D is the best answer. "Significantly" is correct because it means "to an important or notable degree." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: A ("Barely" means "only just," which doesn't fit the context.), B ("Accidentally" means "by chance," which doesn't fit the context.), C ("Never" means "at no time," which doesn't fit the context.).
