In California, a lack of genetic variation in the Argentine ant has allowed the species to spread widely; due to their being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits the spread of this species in its native Argentina.

A.due to their being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits
B.due to its being so genetically similar the ant considers all its fellows to be a close relative and thus does not engage in the kind of fierce intercolnny struggles that limit
C.because it is so genetically similar, the ant considers all its fellows to be close relatives and thus does not engage in the kind of fierce intercolony struggles that limits
D.because they are so genetically similar to one another, the ants consider all their fellows to be close relatives and thus do not engage in the kind of fierce intercolony struggles that limit
E.because of being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits 这题是不是没出好? 虽然答案是C,而且我也知道句末的那个ITS 是指代THE ANT, 所以必须得用单数,但struggles that limits 不是很奇怪吗,struggles是复数吧怎么能用 THAT LIMITS呢?
C:because it is so genetically similar, the ant considers all its fellows to be close relatives and thus does not engage in the kind of fierce intercolony struggles that limits
这里用it来谈论genetically similar,那么it必须是个集体名词。而与之对应的主句主语the ant语义上完全是个体名词,是指某一只蚂蚁。
其次that limit从语义上必须修饰struggles。只有struggles才能limit spread,试问kind怎么可能作为一个核心词去limit 物种的扩张?
所以只有D是正确的。
