Explanation
Correct answer: C.
Choice C is the best answer because as used in the text, “beckoning” most nearly means “inviting,” or attractive. The text portrays a woman who is looking at “trees in their spring beauty.” She compares them to cities, which have their own pleasures even if they do not have the “easy unhuman loveliness” of trees: she thinks of cities as “seductive” and “charming,” both adjectives that signify something that is enticing, or attractive. Therefore, cities that are seductive and charming would also be described as inviting people closer to them.
Why the other choices are wrong
Choice A
Choice A is incorrect because there is no indication in this context that cities are “demanding,” or requiring effort.
Choice B
Choice B is incorrect. Though “signaling,” or communicating something, might be considered a key feature of the act of “beckoning,” in the context here, “beckoning” suggests that cities have attractive qualities that naturally draw people to them. Such attractive qualities are not described by the word “signaling” alone. Therefore, “signaling” is an incorrect answer because it is insufficiently precise.
Choice D
Choice D is incorrect because there is no reason to think in this context that the cities are “shifting,” or changing shape.
