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（C）

(E) and fatigue among shift workers was lowered while raising

fatigue 为什么用reduce来修饰，而不是用lowered?

问题的关键不是FATIGUE用REDUCE还是LOWER的问题（都可以），而是选了D后，“have reduced sickness,”和 “sleeping on the job,”之间应该把逗号换成"AND"
