Set 1: Words in Context (Beginner)

Explanation

Answer: D

PASSAGE

Scientists observed that the animals displayed _____ behavior when threatened, freezing in place rather than running away.

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

A. aggressive
B. typical
C. playful
D. unusual✓ Correct

Detailed Answer Explanation

Choice D is the best answer. "Unusual" is correct because it means "not typical or expected." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: A ("Aggressive" means "ready to attack," which doesn't fit the context.), B ("Typical" means "normal or expected," which doesn't fit the context.), C ("Playful" means "full of fun and energy," which doesn't fit the context.).
