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.

 

1. they have established themselves as supreme adapters in an era when the capability
2. they have established themselves as being supreme adapters in an era when being able
3. it has established itself as a supreme adapter in an era when to be able
4. it has established itself as being a supreme adapter in an era when its ability
5. it has established itself as a supreme adapter in an era when the ability

I think the subject is "the coyote", it refers to the coyote.

Is E the right answer?

Thanks.

E

答案是这样的 但是The coyote is one of several recent ecological success stories:  后面是冒号 那不是说明一个句子已经结束了么

我觉得从句意上说it指代the coyote。冒号不代表一个句子结束了吧

我觉选E还有就是应该用ability,因为后面的has的主语应该是个名词
