OG12-134 关于lowered

134.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

正确答案是C

1. 关于D答案中的lowered，OG上的解释是：inserting lowered before fatigue illogically suggests that fatigue actually increased
我知道D不对，但是对于这个解释我没太明白
2. 如果把C中的while raising 改成 and raised 对吧

谢谢！

double negative = positive

reduced lowered fatigue = increased fatigue

明白了
其实我是想说，把reduced，lowered和raised看成并列为什么不行
不过现在懂了
thank you!
