Think of readingcomprehension as a longer logical reasoning question. The background information or opposing point may have more sentences, but the point and supporting information should be about that same (even if more fleshed out).
Like if this were a readingcomprehension passage and the question was asking me about the authors tone. I would answer something like "mild frustration" not "concerned caution" lol
