PASSAGE

The scientist's research provided _____ data that supported the new theory.

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

A. incomplete
B. outdated
C. questionable
D. reliable✓ Correct

Detailed Answer Explanation

Choice D is the best answer. "Reliable" is correct because it means "consistently good; dependable." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: A ("Incomplete" means "not finished," which doesn't fit the context.), B ("Outdated" means "no longer current," which doesn't fit the context.), C ("Questionable" means "doubtful or uncertain," which doesn't fit the context.).
