Explanation

Answer: D

PASSAGE

The researcher's hypothesis was _____ by subsequent experiments, which produced consistent results across multiple trials.

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

A. refuted
B. ignored
C. complicated
D. validated✓ Correct

Detailed Answer Explanation

Choice D is the best answer. "Validated" is correct because it means "confirmed or supported with evidence." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: A ("Refuted" means "proved to be wrong," which doesn't fit the context.), B ("Ignored" means "deliberately not noticed," which doesn't fit the context.), C ("Complicated" means "made more difficult," which doesn't fit the context.).
