Explanation
Correct answer: A.
Choice A is the best answer because it most accurately describes the main purpose of the text. The narrator describes how Joe responds to being in “the metropolis”: he’s excited and “wild with enthusiasm.” He also envies the young fellows who walk by because, dressed as they are, they look as if they have somewhere special to go. The text contrasts this new place with the place Joe comes from, where apparently there wasn’t as much to do. Thus, the main purpose of the text is to illustrate Joe’s reaction to a new environment.
Why the other choices are wrong
Choice B
Choice B is incorrect because the text makes no reference to why Joe has moved. The narrator indicates that Joe is enthusiastic about being in a city, but there’s no explanation provided for the move.
Choice C
Choice C is incorrect because the text makes no reference to how Joe thinks about an event. The narrator describes young men passing by in the evening and then recalls places worth going to at home—church and a few people’s houses—but there’s no explicit comparison made nor is a time of day mentioned for these events back home.
Choice D
Choice D is incorrect because the text doesn’t support the idea that Joe feels regret over leaving home. Instead, Joe is described as “wild with enthusiasm” at being in the city. Joe’s home is mentioned, but only to compare it unfavorably with the city.
