The enzyme's catalytic efficiency _____ that of previously studied variants by several orders of magnitude.
Which choice completes the text with the most logical and precise word or phrase?
A. matches
B. mimics
C. trails
D. surpasses✓ Correct
Detailed Answer Explanation
Choice D is the best answer. "Surpasses" is correct because it means "exceeds or goes beyond." The context clues in the passage indicate that this meaning best completes the sentence logically.
Why others are wrong: A ("Matches" means "equals," which doesn't fit the context.), B ("Mimics" means "imitates," which doesn't fit the context.), C ("Trails" means "falls behind," which doesn't fit the context.).
