The anthropologist's research _______ long-held assumptions about early human migration patterns. DNA evidence from newly discovered fossils suggested routes that previous scholars had considered impossible.
Which choice completes the text with the most logical and precise word or phrase?
supported
overturned
memorized
illustrated
Correct Answer: B
Choice B is the best answer. The passage states new evidence suggested routes "previous scholars had considered impossible," indicating a fundamental challenge to existing beliefs. "Overturned" means to reverse or invalidate, fitting this paradigm shift.
Choice A is incorrect because "supported" contradicts challenging assumptions. Choice C is incorrect because "memorized" doesn't relate to challenging ideas. Choice D is incorrect because "illustrated" suggests demonstrating, not disputing.
