不是说a of b,which...这里which修饰的是b吗，求牛牛解答所以这里a(found) b(that) c(that) d(found) e（which）各修饰的是sloth还是fossils of the arm of a sloth,选项中的其他问题我都明白，只是of短语的修饰太头疼了！O(∩_∩)O谢谢！

如果光看这个修饰结构啊，你肯定能排除明显错的B，E项对吧。那ACD项的修饰结构都是同等的呀，你得往下看才能排除了。所以纠结在到底修饰哪个就没必要了呀。

可以认为 of the arm of a sloth 是用来 define 这个 fossils 的，只能把它们看成整体才有意义。
所以后面的modifier应该是修饰Fossils of the arm of a sloth这个整体。
特别是从句意上明显不可能修饰sloth。

（参加 ManhattanGMAT SC 中的 mission-critical modifier）
例句为An ice sheet covers 80 percent of the surface of Greenland, an area roughly the size of Alaska.
