GWD-24-41.

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 intercolony 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

答案是C 我选D

当然D错是因为结尾in its native Argentina.所以要用单数. 可是C的话thus does not engage in the kind of fierce intercolony struggles that limits这个that难道又是跳开来修饰前面的kind吗？

that 指代 the kind (of fierce intercolony struggles), 单数, 后面动词用三单现,排除B,D. 此外分号后面接句子,B的句子结构不对

A: due to their being so .... 介词后面加动名词我总觉得罗嗦,而且描述很冗长

E:because of being 也是用介词带动名词组成介宾短语，很罗嗦~

C才是比较简单的答案~

此外在句尾出现in its native Argentina, 说明要反回去看指代对象,D的they,their就没有与its对应~也该排除掉A,D,E

题号呢？
