Answer: B

PASSAGE

Recent discoveries have _____ challenged long-held assumptions about dinosaur behavior.

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

A. temporarily
B. fundamentally✓ Correct
C. partially
D. barely

Detailed Answer Explanation

Choice B is the best answer. "Fundamentally" is correct because it means "in a central or primary way." The context clues in the passage indicate that this meaning best completes the sentence logically.

Why others are wrong: A ("Temporarily" means "for a short time," which doesn't fit the context.), C ("Partially" means "to some extent," which doesn't fit the context.), D ("Barely" means "only just," which doesn't fit the context.).
