OG13 SC134关于C选项

lqlq1232004

Recently implemented "shift-work equations" based on studies of the human sleep cycle have reduced sickness, sleeping on the job, fatigue among shift workers, and have raised production efficiency in various industries.

(A) fatigue among shift workers, and have raised

(B) fatigue among shift workers, and raised

(C) and fatigue among shift workers while raising

(D) lowered fatigue among shift workers, and raised

(E) and fatigue among shift workers was lowered while raising
我的问题是关于C选项：while不是只能是名词或连词吗？作为连词的while，后面接的ing形式真的合适吗？如果合适，请赐教这是哪条语法规则呢？这个ing究竟是noun modifier 还是想表达verb modifier的意思呢？谢谢大家！

这里是省略 while当连词的时候 一个是转折 一个意思是当…的时候，while doing 其实是 while equations are raising的省略

为什么我总感觉是 while have raised production 呢？？？


难道不应该是么，已经完成或者持续影响的感觉？


OG 的解释如下

the phrase while raising provides a clear contrast with have reduced.

为什么说这个ing就能直接对比have reduced呢？

我还看到有人解释是 while doing继承主句时态，while have raised。这句话我就不是很明白，求解答啊~
