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

A. useless
B. obvious
C. wrong
D. valuable✓ Correct

Detailed Answer Explanation

Choice D is the best answer. "Valuable" is correct because it means "of great worth." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: A ("Useless" means "having no use," which doesn't fit the context.), B ("Obvious" means "easily perceived," which doesn't fit the context.), C ("Wrong" means "incorrect," which doesn't fit the context.).
