The coyote is one of several recent ecological success stories:  along with the white-tailed deer, the moose, and other species that are enlarging their natural domains, they have established themselves as supreme adapters in an era when the capability to adjust to the environmental changes wrought by human beings has created a whole new class of dominant large mammals.

A.    they have established themselves as supreme adapters in an era when the capability
B.    they have established themselves as being supreme adapters in an era when being able
C.    it has established itself as a supreme adapter in an era when to be able
D.    it has established itself as being a supreme adapter in an era when its ability
E.    it has established itself as a supreme adapter in an era when the ability
选了C，后面半句话是神马意思呢 ？

如果我没做错的话，题目应该选E，你下次记得把OA附上。

AB因为they无指代，错！
C因为to be able不定式作主语错！
D中的as being错！
E正确

我觉得应该选E，这是一个when引导的从句，（状语从句还是定语从句拿不准）修饰era
我觉得翻译应该是：
在“适应人类造成的环境变化的”能力创造了一类全新的大型哺乳类动物的era时
这句话的主干是ability has created a new class of mammals
