Explanation
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.).
