问题     Except in special situations, human beings’ battle with mosquitoes will not be won by a simple campaign to eliminate the insects. Social tradition and habits, it seems, do much to ensure continual contact between mosquitoes and people. On the slopes of Mount Kilimanjaro, for example, mosquitoes breed in the leaf axils of a plant called dracaena. Although dracaena is not a food plant for humans, its use as a hedge or boundary marker is deeply rooted in tradition. Here, as in other parts of the world, human behavior ensures contact and conflict between people and mosquitoes.
    I am not advocating a policy of live and let live; we already know that living with mosquitoes is very unpleasant. But until we accomplish the difficult task of understanding how our habits often perpetuate—even create—our problems, efforts to resolve our battle with mosquitoes will probably fail.
Which of the following best describes the organization of the passage?

E、A problem is identified, a solution is proposed, and potential difficulties with the solution are raised.
答案C
解析 本题属于结构性主旨题，正确选项中的虚词应该和文章内容对应，选项C正确。a claim对应“传统导致人类赢不了蚊子”，a supporting example指乞力马扎罗山的例子，a conclusion对应第二段的结论“赢不了”。
