GRE Sample Test 4 Verbal Reasoning 1

The verb “cites” indicates that this is a Detail question, so look directly in the passage for the answer. The first two lines of the passage state that Iranian Americans call themselves Persian, and “this descriptor is a frequent cause of confusion among non-Persians.” Bingo. Choice (E) is a perfect match. Choice (A) is a misused detail. It’s a reason why some people oppose the use of the term Persian, not a reason why non-Persians are confused by the term. Similarly, choices (B), (C), and (D) all relate to arguments about whether the term Persian should be used; none of them have anything to do with the cause of some non-Persians’ confusion, which is what the question asks for.
