问题 What can people know from the crown of an ancient tree found in New York?
According to the fossil reconstruction, what main parts did a tree comprise?

选项 A、It comprised a trunk, vertical ridges and palms.
B、It comprised leaves, ferns and palms.
C、It comprised stumps, branches and palms.
D、It comprised a base, a trunk and a crown.

答案D

解析 根据题干中the fossil reconstruction,可以定位到第四段。这段提到了通过化石的重组,科学家们断定一棵由全部这些部分组成的树会长到30英尺高,这些部分主要是指结实的根基部,巨大的树干和没有叶子的树冠。题目问的是组成树的主要部分,vertical ridges不是主要部分,它属于树干,而palms不是组成古树的一部分,故可排除A;leaves,ferns and palms都不是组成树的部分,故可排除B;stumps and palms不是组成树的部分,而branch不是主要部分,故可排除C。
