The geologist described the rock formation as anomalous, noting that its mineral composition differed significantly from every other sample collected in the region over the past century.
As used in the text, what does the word "anomalous" most nearly mean?
typical
beautiful
unusual
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.
