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'

key: D

但是搞不懂这个shifs是怎么回事，shifts 跟work 一起？ 意思不懂？

shift相当于中文里的“班”，早班，中班，晚班的班。to work the shift 就是"上班"

FYI:

Shift work is an employment practice designed to make use of the 24 hours of the clock, rather than a standard working day. The term shift work includes both long-term night shifts and work schedules in which employees change or rotate shifts

A related yet different concept, the work shift, is the time period during which a person is at work.

所以shifts是上班时间的意思...

这句话该怎样理解？：

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 
                that married women with children under eighteen were more likely than other married women to work shifts different from their husbands'

their husband·s 和哪部分对应？
