请教GWD24-41

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 ants considers all its fellows to be a close relative 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

给的答案是D,

但我觉得该题A,C,D,E都有单复数指代问题,

Aue to their being so genetically similar to one another: 原文是ant, species,包括划线部分后面也是in its native Argentina 都是单数,故A错

C:划线部分后半句the ants considers all its fellows 矛盾 错

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划线部分三个复数名词和后面的in its native Argentina 矛盾, 错

E:the ants consider all their 和后面的in its native Argentina 矛盾, 错

故,虽然B中的DUE TO不是很好,但符合correct原则. 我选B

请指教:

前面的they 和 their 都是指代ants，而最后的its指代 this species，这一物种(看成一个整体)，由于species单复数相同，可以从this判断是单数。

However, the singular form "ant", and "its" have been all over the place in the non-underlined part. There is no indication that plural form "ants" should be used in the underlined part. Look at the non-underlined parts:

a lack of genetic variation in the Argentine ant has allowed the species to spread widely

the spread of this species in its native Argentina.

agree with lES. D.

1，ACE的单复数struggles that limits不对

2，B中Due to its being so genetically similar 。。awkward.

3，从上下文来看应该用复数

相较于GWD1-13，GWD24的SC题型个人觉得错误蛮多的，与ETS的风格大异其趣，难以苟同。

估计背题者背出来的时候可能就不完整了，又加入自己的意思来补全，所以才会出现类似此题"consider A to be B"这种完全不合ETS惯用语的大错误@_@

这题真的很奇怪，consider sth to be是明确被ets批判的用法，竟然在五个选项里都有。另外，我有一个问题，D选项里的：the kind of fierce intercolony struggles that limit 这个limit用的对么？我记得ets很喜欢的一个陷阱就是：单数名词 of 复数名词 that 复数动词，这里是不是有这样的错误存在呢？

同意，这一套题的确有些地方和ETS常用的想法有出入…

另外﹙A﹚﹙B﹚我看到时就删了，不是说due to只能不能放在句道吗?
