(B) toward workers in all-night plants being inefficient

(C) to workers in all-night plants who are inefficient

(D) to combat worker inefficiency in all-night plants

(E) to decreased efficiency among workers in all-night plants

为什么选E?

只有insomnia in travelers 和 efficiency among workers才平行对称

from chronic insomnia in frequent transcontinental air travelers to decreased efficiency among workers in all-night plants

谢谢楼上,再请问一下二楼,这题的平行是这样理解么?
