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

A

sufficient

B

excessive

C

inadequate

D

perfect

Correct Answer: C

Choice C is the best answer. The passage states researchers "argue for dramatically expanded programs," indicating current efforts fall short. "Inadequate" means insufficient, fitting this call for expansion.

Choice A is incorrect because "sufficient" contradicts need for expansion. Choice B is incorrect because "excessive" contradicts expansion calls. Choice D is incorrect because "perfect" contradicts criticism.
