A
groundbreaking
B
predictable
C
trivial
D
irrelevant
Correct Answer: A
Choice A is the best answer. The passage describes discovery providing "first physical evidence" for a long-doubted theory. "Groundbreaking" means pioneering and important, fitting this paradigm-shifting find.
Choice B is incorrect because "predictable" contradicts being first evidence. Choice C is incorrect because "trivial" contradicts proving a major theory. Choice D is incorrect because "irrelevant" contradicts significant proof.
