Microbiologists like Dr. Aris Thorne spend much of their time _______ what is invisible to the naked eye: using high-powered electron microscopes, they closely analyze the structural integrity of bacterial cell walls.
Which choice completes the text with the most logical and precise word or phrase?
selecting
inspecting
creating
deciding
Correct Answer: B
Choice B is the best answer. The text states that the microbiologists "closely analyze the structural integrity" of cells. "Inspecting" means looking at something closely, which is a synonym for analyze or examine.
Choice A is incorrect because "selecting" means choosing, which is not the primary activity described (analyzing structure). Choice C is incorrect because they are observing existing cells, not "creating" them in this context. Choice D is incorrect because "deciding" involves making a choice, not the act of observation described.
