Explanation
Correct answer: A.
Choice A is the best answer because it most accurately describes the main purpose of the text. The narrator asserts that she loves both her “own” country (Japan) and her “adopted country” (the United States) even though the two countries differ “widely.” She also indicates that, at first, she would try to explain unfamiliar experiences that she had in the United States using the standards ingrained in her from growing up in Japan. Thus, the main purpose of the text is to convey the narrator’s experience of observing and making sense of the differences between two cultures she embraces.
Why the other choices are wrong
Choice B
Choice B is incorrect because the text makes no reference to possible companions. Although the text does indicate that the narrator sometimes used the cultural framework she acquired growing up in Japan to explain some experiences she’s had, there is no suggestion that this was in service of making friends. And although “no one seemed to know” strongly implies that the narrator has interacted with other people in the United States, there is no indication that these conversations involved her discussing Japanese customs.
Choice C
Choice C is incorrect because nothing in the text suggests that the narrator was hesitant to ask questions. In fact, the narrator indicates that “no one seemed to know the origin” of various customs, which provides evidence that, rather than being hesitant, she sought information from several people.
Choice D
Choice D is incorrect because the text makes no reference to the physical distance between Japan and the United States. Although the narrator indicates that the two countries differ “widely” and likens them to “two separate worlds,” these descriptions relate to cultural aspects of the countries and the narrator’s feelings about the two countries, not the physical distance between them.
