问题 What can people know from the crown of an ancient tree found in New York? [br] 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。
