看了大家的讨论，觉得这道题还是没有解决，大家来再看看吧，希望NN指导
In California, a lack of genetic variation in the Argentine ant hasallowed the species to spread widely; due to their being so geneticallysimilar to one another, the ants consider all their fellows to be a closerelative and thus do not engage in the kind of fierce intercolony strugglesthat limits the spread of this species in its native Argentina.
A. due to their being sogenetically similar to one another, the ants consider all their fellows to be aclose relative and thus do not engage in the kind of fierce intercolonystruggles that limits
B. due to its being sogenetically similar the ant considers all its fellows to be a close relativeand thus does not engage in the kind of fierce intercolony struggles that limit
C. because it is sogenetically similar, the ant considers all its fellows to be close relativesand thus does not engage in the kind of fierce intercolony struggles thatlimits
D. because they are sogenetically similar to one another, the ants consider all their fellows to beclose relatives and thus do not engage in the kind of fierce intercolonystruggles that limit
E. because of being sogenetically similar to one another, the ants consider all their fellows to be aclose relative and thus do not engage in the kind of fierce intercolonystruggles that limits
主要是在选择的时候首先用limit 排除了CE，因为that limit 应该修饰the kind of fierce intercology struggles,这个为什么不是复数名词么》？
其实根据最后的一句its native 排除了they的选项。
