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.

先看选项是they it，知道选哪个就有50%的概率选中了。
从开头 The coyote is one of xxx，用的是is，第三人称单数形式，直接排除了 AB；
剩下 CDE，看完后半段句型 xxx has created，感觉只有DE（肯定是个n）能接了；再看DE，D established itself as being，being 非常冗余，排除；（GMAT很爱考这种）
选E。
