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

A

negligible

B

beneficial

C

dire

D

ambiguous

Correct Answer: C

Choice C is the best answer. The text lists "crucial" roles (absorbing CO2, etc.). Losing these would be bad. "Dire" means extremely serious or urgent (in a bad way).

Choice A is incorrect because "negligible" means insignificant. Choice B is incorrect because "beneficial" means good. Choice D is incorrect because "ambiguous" means unclear.
