A. than

B. than born

C. than they were

D. than there had been（A）考点：

E. than had been born

我认为比较的对象是： more babies were born to women over the age of thirty 比（babies were born to women） under it。

为什么能这么省呢？

大家有什么看法？

因为BCDE错得天昏地暗，所以选A~呵呵

补全的话应该是those were born to women under it ~其他选项完全错了。。。所以选A

呵呵，楼上说得对。

但是除此之外，你得弄懂A为什么能这么省。

比较在GMAT中一直是难点，是因为ETS并不每次都给你错得天昏地暗的4个选项。
