Though subject to the same wild-animal control efforts that killed off almost all the wolves in North America over the past century, the coyote's amazing ability of adapting to the presence of humans has enabled it to expand its range into Alaska and Central America.

A. coyote's amazing ability of adapting to the presence of humans has enabled it to expand its

B. coyote, because of its amazing ability of adapting to the presence of humans, have been able to expand their

C. coyote, because of its amazing ability to adapt to the presence of humans, has been able to expand its

D. amazing ability of the coyote to adapt to the presence of humans have enabled it to expand the

E. amazing ability of the coyote to adapt to the presence of humans has enabled it to expand the

答案是c，我选的e，求解答~！

嗯  我也栽栽了subject to的主语的选择上了。我的问题是：我肯定知道这个结构要去找subject to的主语 但是对于这个短语的意思或者说其主语的判断出了问题，判断成了“ability”了。

那么，除了subject to主语选择的问题，该题目的选项还有其他的错误吗？或者说E还有别的错误吗？谁知道？

thx.

E it的话 指代会不清楚，从原文逻辑意思应该是小狼的range 这里就不明确了

C的话前面because插入语这里，出现了its，就近只能指代小狼，后面又出现了it,两个代词意思要一致，所以C正确

PS：B的话还有主谓不一致吧~
