Which choice completes the text with the most logical and precise word or phrase?

A

quarrel about

B

dearth of

C

profusion of

D

verisimilitude in

Correct Answer: B

Choice B is the best answer. The text sets up a contrast using "while": there are "countless studies" of shallow waters, but there is a _______ of studies of the deep trench. "Dearth of" means a scarcity or lack of, which provides the logical contrast to "countless."

Choice A is incorrect because "quarrel about" implies a disagreement, not a quantity, which is what the contrast requires. Choice C is incorrect because "profusion of" means an abundance, which would not contrast with the abundance of shallow water studies. Choice D is incorrect because "verisimilitude" means the appearance of being true or real, which does not fit the context of the quantity of studies.
