PASSAGE

The species developed _____ adaptations to survive in the desert environment.

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

A. unique✓ Correct
B. common
C. temporary
D. harmful

Detailed Answer Explanation

Choice A is the best answer. "Unique" is correct because it means "being the only one of its kind." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: B ("Common" means "occurring frequently," which doesn't fit the context.), C ("Temporary" means "lasting a short time," which doesn't fit the context.), D ("Harmful" means "causing damage," which doesn't fit the context.).
