A survey of 765 working women over eighteen years of age found that 60 percent of them worked 40 or more hours a week and for married women with children under eighteen it was more likely that they would work different shifts from their husbands.
(A) for married women with children under eighteen it was more likely that they would work different shifts from their husbands
(B) for married women whose children were under eighteen, they were more likely than other married women to work shifts different from their husbands'
(C) when married women had children under eighteen it was more likely for them to be working different shifts from those of their husbands'
(D) that married women with children under eighteen were more likely than other married women to work shifts different from their husbands'
(E) that when married women had children under eighteen they were more likely to be working shifts that differed from their husbands
答案是D，这里they出现两次，但是指代的对象不同。
代词指代出现两次指代对象必须一致，这个只是在分号隔开的两句中出现过特列，难道两个宾语从句并列，也可以是特例么？
当然最后还是选了这个，发现现在prep2的sc的答案好像是在选最优答案一样，呵呵 |
