Detailed Answer Explanation
Choice C is the best answer. "Directly" is correct because it means "in a straightforward manner." 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 ("Vaguely" means "unclearly," which doesn't fit the context.), D ("Accidentally" means "by chance," which doesn't fit the context.).
