GWD24-41，请教关于分词

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.

我可以判断出答案，也看了原来的提问帖。不过还是想请教一下，想上面那种带 being 的选项，什么时候对？经常看到这样的选项，但是不知道什么时候应该用 being 呢？拜谢。

一般而言， being + verb. 错。

但是， perp. + being 就不一定错；however, 在 prep. 后名词优于动名词，所以有名词的时候不选有being 的。

多谢Joe ! 再问一句，下面这个题里边分词做句子的什么成分？

185. The recent surge in the number of airplane flights has clogged the nation's air-traffic control system, to lead to 55 percent more delays at airports, and prompts fears among some officials that safety is being compromised.

(A)  to lead to 55 percent more delays at airports, and prompts

(B)  leading to 55 percent more delay at airports and prompting

(C)  to lead to a 55 percent increase in delay at airports and prompt

(D)  to lead to an increase of 55 percent in delays at airports, and prompted

(E)  leading to a 55-percent increase in delays at airports and prompting

是伴随吗？还是强调整句话的结果？那分词伴随动词还是修饰整个句子怎么分呢？再次拜谢！

楼上说的对，是修饰整个句子（The recent surge ... air-traffic control system) 做结果壮语。
