我选D,答案是C。搜了讨论贴,没有定论。C的问题是,it is so genetically similar,it指代谁呢,the ant这个种类吗?ms也说得过去,这个族群在基因上很相似。但后面limits的问题就大了,明显是struggles会limit the spread of this species,如果说修饰kind就太牵强了。D也有点不对劲,后面未划线中的its似乎暗示前面应该用单数形式,不过看到有人说指代species也是可以的。
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
c里面 kind of fierce intercolony struggles that limits,主(要)语是kind of,所以单数
d的问题是 one another,没这用法
