Explanation
Correct answer: C.
Choice C is the best answer because it best describes the function of the underlined portion in the text as a whole. The text begins by defining alternative-history fiction as a subgenre centered on “what if?” questions. The underlined portion then poses two such questions—one about India starting the Industrial Revolution and one about Soviet cosmonauts landing on the moon first. The sentence that follows refers to the two questions as “speculative counterfactuals like these,” confirming that the underlined questions serve as examples. Thus, the underlined portion provides examples of the types of scenarios addressed in alternative-history fiction.
Why the other choices are wrong
Choice A
Choice A is incorrect because the underlined portion provides examples of “what if?” scenarios, not evidence of a line of influence from academic historians to fiction writers; nothing in the text addresses such a relationship. The text mentions academic historians only in the context of how alternative-history stories can supplement their work.
Choice B
Choice B is incorrect because the text states that counterfactuals like the ones presented in the underlined portion are “commonly deployed by academic historians,” indicating engagement with such questions rather than neglect. Instead of acknowledging overlooked questions, the underlined portion provides examples of the types of scenarios addressed in alternative-history fiction.
Choice D
Choice D is incorrect because nothing in the text indicates that the specific questions in the underlined portion originated with fiction writers or that they subsequently inspired academic historians. Instead, the underlined portion simply illustrates the kind of “what if?” questions typical of the alternative-history fiction subgenre.
