求教：怎样区分哪部分才是比较的对象？

paige123

如题，我遇见比较的题总是犯晕，不知道要比较的到底是哪部分比如此题：
In 1982 the median income for married-couple families with a wage-earning wife was $9,000 more than a family where the husband only was employed.
(A) a family where the husband only
(B) of a family where only the husband
(C) that for families in which only the husband
(D) a family in which only the husband
(E) those of families in which the husband only
此题选C即比较的是the midian income,可是怎么才能看出来比较的是这个而不是families？？求各位大虾指教，感谢

这道题我是这样理解的： the median income for married-couple families with a wage-earning wife 中的核心词是the median income，后面的那一大堆都可以看作是对于the median income 的修饰，那么这道题就可以简化成the median income  was $9,000 more than ( ), 从逻辑含义来看，“收入A比收入B多9000”，而不能说“收入A比家庭多9000”，对吧，因此比较的对象一定是收入而不是家庭了。
