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

这道题为什么选C呢？？
祝大家新的一年里心想事成，杀G成功！ 嘿嘿

because of being / due to being ... 没有because简洁 排除
为划线部分the spread of this species in its native Argentina.    its说明用单数 所以排除D

为什么struggles可以用limits，主谓一致没问题吗？

liverpool123

我觉得宁可选择D，c的定语从句不可能跳跃修饰kind that很不合理吧

d用they可以和its不矛盾，its与后面的this species相对

我和3楼上的观点一样
未划线部分确实用的是its
但是struggles和 limits 又怎么解释呢
