[求助]OG12 134 未划线部分主谓一致的问题

昕昕

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想问一下OG上的解释貌似是 implemented “shift-work equations”是have reduced的主语, 但是为何谓语是负数形式呢, 求教?
PS. gmatpills上给的解释说studies是have reduced的主语, 那么理解主句不就没有谓语了吗?
really confused me , some for help, thax!!!!!!!

楼主， implemented “shift-work equations”是have reduced的主语，这点是无疑的，based on the study ...是用来修饰 shift-work equations，所以studies不可能是have reduced的主语，另外，谓语当然是复数形式啊，主语是equations 而不是equation。不知道你懂没？
