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.
they have established themselves as supreme adapters in an era when the capability
they have established themselves as being supreme adapters in an era when being able
it has established itself as a supreme adapter in an era when to be able
it has established itself as being a supreme adapter in an era when its ability
it has established itself as a supreme adapter in an era when the ability
看清主语是The coyote，along with xx，xx and xx是从句，排除AB
C：when引导的定语从句后面不定式做主语to be able to adjust指未来能调整这件事，不能接has created，时态冲突了，错误。
D&E的区别是its ability还是the ability，结合when前面主句的句意来看，竹居士说它使自己成为一个超级适应者在一段时期内，这一段时期应该是在讲它的能力怎么样，用its ability更为合适。
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。
看著句，说的是coyote这一个种类，和主句一致用it
1、5个答案中最明显的不同是首尾的不同！along with A,B and C这个只是状语从句，主谓一致还是看主句的主体。首先，我们该判断是“it”还是“they”？这要求我们理解整句话的意思。“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”这句话想说的是郊狼是个成功的案例，这个成功的案例是：“it has established itself as a supreme adapter in an era when the ability...”（中文翻译：“it”它，郊狼是一种适应能力很强的物种。）所以答案只能从C/D/E里面寻找！
2、在看C/D/E的句尾,区别是“ability”&“be able to”!根据句子的完整性原则，答案只能是：the ability has created a whole new class of dominant large mammals.所以排除答案C。to be able表示的是将来，逻辑错误。并且when从句无主语了，注意后面有has created，需要一个主语来发起这个动作
3、the ability强调的是能力本身，而its ability强调郊狼的这种能力。个人觉得，E选项的the ability没有错，但是its ability更好，选D！
但是D比E多了being，being显得很多余！
所以，只有根据优先性原则，说话啰嗦是重罪!故选E！
这里的代词指的是coyote，应该用it，排除AB,D.选项being多余；C.to be able to表示目的或者将来的时间，逻辑语义错误
along，介词，沿着，如：walked along the road；副词，向前，如：get along with sb，drove along驱车前行，come along一起来。
along with=with，
a whole new class of dominant large mammals，of表同位关系，大型哺乳动物的统治阶层；如果是the domination of large mammals，则of表动作的对象，对大型哺乳动物的统治
是ability has created a whole new class，不是to be able to adjust做主语
establish sb as sth.
D选项错误在于being多余？
A B coyote单数
D as being中being冗余
C选项 to be able 表示将来，逻辑错误；D，its ability变成具体指代，不合逻辑
