As used in the text, what does the word "unprecedented" most nearly mean?

A

expected

B

unmatched

C

slow

D

predictable

Correct Answer: B

Choice B is the best answer. The passage emphasizes the rate is beyond "recorded history" and faster than models predicted. "Unmatched" captures this sense of being without equal or comparison.

Choice A is incorrect because "expected" contradicts exceeding predictions. Choice C is incorrect because "slow" contradicts faster than predicted. Choice D is incorrect because "predictable" contradicts exceeding models.
