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

A

typical

B

beautiful

C

unusual

D

ancient

Correct Answer: C

Choice C is the best answer. The passage describes composition that "differed significantly from every other sample." "Unusual" captures this quality of being different from the norm.

Choice A is incorrect because "typical" contradicts differing significantly. Choice B is incorrect because "beautiful" doesn't relate to composition. Choice D is incorrect because "ancient" refers to age, not uniqueness.
