PASSAGE
The enzyme activity was _____ reduced in the presence of the inhibitor.
Which choice completes the text with the most logical and precise word or phrase?
A. never
B. dramatically✓ Correct
C. accidentally
D. barely
Detailed Answer Explanation
Choice B is the best answer. "Dramatically" is correct because it means "in a sudden and striking way." The context clues in the passage indicate that this meaning best completes the sentence logically.
Why others are wrong: A ("Never" means "at no time," which doesn't fit the context.), C ("Accidentally" means "by chance," which doesn't fit the context.), D ("Barely" means "only just," which doesn't fit the context.).
