Explanation
Correct answer: A.
Choice A is the best answer. The example of Tobar approaching his subject “like a reporter,” including conducting “interviews” and “research,” shows Tobar applying journalism techniques to his fiction-writing.
Why the other choices are wrong
Choice B
Choice B is incorrect. This choice doesn’t support the claim. It tells us about Tobar’s initial career as a journalist, but it doesn’t say anything about him “applying journalism techniques” to his fiction-writing.
Choice C
Choice C is incorrect. This choice doesn’t support the claim. It tells us that Tobar applied fiction techniques to his nonfiction writing, but we’re looking for evidence of the other way around: that Tobar applied journalism techniques to his fiction-writing.
Choice D
Choice D is incorrect. This choice doesn’t support the claim. It tells us that a character in one of Tobar’s novels applied a journalism technique to his fiction-writing, but it doesn’t tell us that Tobar did that himself.
