Explanation
Correct answer: B.
Choice B is the best answer because it presents a statement about the Turkins that is suggested by the text. The text explains that while many pleasant families live in the city of S., inhabitants of the city consider the Turkins to be "the most accomplished and most enlightened family of all." Thus, by indicating that they are seen as more accomplished and more enlightened than all the other families in the city of S., the text suggests that the Turkins have a unique status there.
Why the other choices are wrong
Choice A
Choice A is incorrect because the text doesn’t indicate that the Turkins have recently moved to the city of S.; it provides no information about when the Turkins arrived.
Choice C
Choice C is incorrect because the text explains how the Turkins are viewed by others in the city of S. but gives no indication of how the Turkins feel about living there.
Choice D
Choice D is incorrect because the text explains how the Turkins are viewed by other residents of the city of S. but gives no indication of how the Turkins view the other residents.
