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

OA:E    对OG上C,E的解释比较疑惑，我把解释贴出来

C:the meaning of 55 percent increase in delay is not clear.

E:the phrase a 55 percent increase in delays is clear and concise

明明在选项里面CE中的这个部分都是a 55 percent increase in delay 只是delay的单复数不一样而已，怎么评价就不一样？？！！

前面都用55%了，就说明这环境下delay是可数的

那其他的问题呢

题意应该是航班延误率，或延误的航班数量增加，所以才用an increase of 55 percent in delays ，表示一个量的增长
但C中的...a 55 percent increase in delay at airports and prompt. 不清楚，不知道是使航班的延误时间增加了55%, 还是延误的航班数量。且它用的单数，如果可能则只可能指延误时间。而这只对一个航班才比较说得过去的。但可想而知，不太合理。因为既然影响到整个air-traffic系统，那就不止一个航班了，所以.....呵呵~

首先只考虑 leading, 表伴随 而非to lead 表目的——A，C，D就可以直接排除了...
——剩B，E

leading to的to 是介词，后边应跟名词。——排除B——答案E

而且and后边的Prompt 要与之前的动词时态平行
从原文给的意思上看，prompt fear 应该是由于flight has clogged，作为表示其结果的状语，因此应该和前边的leading to是同一层次的，因此应该用prompting.
