Climate scientists warn that rising sea levels pose an _______ threat to coastal communities worldwide. Without significant intervention, millions of people may be displaced by flooding within the next few decades.
Which choice completes the text with the most logical and precise word or phrase?
imaginary
ancient
amusing
imminent
Correct Answer: D
Choice D is the best answer. The passage emphasizes that displacement could occur "within the next few decades," indicating a threat that is approaching soon. "Imminent" means about to happen, fitting this urgent timeline.
Choice A is incorrect because "imaginary" contradicts the scientific warning described. Choice B is incorrect because "ancient" refers to the past, not future threats. Choice C is incorrect because "amusing" inappropriately suggests the threat is entertaining.
