PASSAGE

The enzyme's function is _____ dependent on the presence of specific cofactors.

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

A. critically✓ Correct
B. randomly
C. independently
D. barely

Detailed Answer Explanation

Choice A is the best answer. "Critically" is correct because it means "in a way that is crucial." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: B ("Randomly" means "without pattern," which doesn't fit the context.), C ("Independently" means "in a way that is free from outside control," which doesn't fit the context.), D ("Barely" means "only just," which doesn't fit the context.).
