Climate scientist Dr. Arlene Foster admits that while she lacks definitive data on the timeline, she _______ that global sea levels will eventually necessitate the relocation of major coastal cities. This theory drives her current advocacy for updated urban infrastructure.
Which choice completes the text with the most logical and precise word or phrase?
demands
speculates
doubts
establishes
Correct Answer: B
Choice B is the best answer. The text says Foster "lacks definitive data" but has a "theory." "Speculates" means to form a theory or conjecture about a subject without firm evidence, which fits perfectly.
Choice A is incorrect because "demands" implies a command, not a theoretical thought. Choice C is incorrect because the text says she thinks relocation will happen (her theory), so she doesn't "doubt" it. Choice D is incorrect because "establishes" implies proving something is true, but she admits she lacks definitive data.
