问题 What can people know from the crown of an ancient tree found in New York? [br] Why was it possible for these ancient trees let more light through than modern ones?

选项 A、Because they were closely spaced, only 3 to 16 feet apart.
B、Because they were smaller plants and shrubs.
C、Because their branches did not fan out as far as to form a shape like umbrella.
D、Because they had very small leaves like that of fern and dropped easily.

答案 C

解析 根据题干中let more light through,可以定位到第五段最后一句。这句提到了这些古老的树木可能会比现代的树木更能够透射阳光,因为它们树枝的结构不是向四周扩展的很远以致形成伞状。这些古树长得很密不是它们能透射更多的阳光的原因,故可排除A;小植物和灌木只是古老森林的一部分而不是所有的树木都这样,而且这也不是能透射更多阳光的原因,故可排除B;这些树木的叶子小而且容易掉也不是能透射更多的阳光的原因,故可排除D。
