GWD-24-41.（查过版主AlienX发言：有人选C有人选D没结论）

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.

我觉得c和d纠结在a kind of fierce intercolony struggles 是单数还是复数的问题 ，因为不管用it还是用they是要从头到尾都用一个就行。有nn发表一下意见 a kind of A(复数名词）是属于单数还是复数吗？

the kind of...

Vote for C,

i change my choice from d to c, 

"the kind" is the subject of the clause, so the predicate should be "limits"

我选D，我觉得关键在similar 后的内容，C similar 后没有东西，意思不明确；而D similar 后加 to one another, 就比较清楚，什么 similar

愚见，大家评评
