Climate researchers have warned that current conservation efforts are _______ to address the scale of biodiversity loss occurring worldwide. They argue for dramatically expanded programs.
Which choice completes the text with the most logical and precise word or phrase?
sufficient
excessive
inadequate
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.
