问题     When an art museum wants a new exhibit, it buys things in finished form and hangs them on its walls. When a natural history museum wants an exhibit, it often must build it realistically— from a mass of material and evidence brought together by careful research.
    An animal, for example, must first be skinned. Photographs and measurements are used to determine the animal’s structure in a natural position fighting, resting, or feeding. Then muscle forms are built and a plaster shell is made. Finally the skin is pulled over the shell like a wet glove. This completes the animal subject.
    Displaying such things as stone heads, giant trees, and meteorites (陨石,陨星) is basically mechanical. Most other natural history exhibits present more difficult problems. For instance how can a creature be exhibited when it is too small to be seen clearly? In these cases larger-than-life models are built. The American Museum of Natural History has models of fleas (跳蚤), houseflies and a myriad (无数的) of other insects enlarged up to seventy-four times. The models show the stages of the insects’ development and the workings of their bodies.
The best title for this passage is______.

选项 A、Constructing an Animal Subject
B、Problems of Exhibiting Natural History
C、Natural History
D、Building a Museum Exhibit

答案B

解析 本题是一道涉及全文最佳标题类的问题。根据文章内容,我们可以总结归纳出本文的中心思想和主题,从而推断出本文的最佳标题应是展示自然历史的困难和问题。因此,本题的正确答案应是B。
