标题: 大全-17-16

16. The proportion of women among students enrolled in higher education programs has increased over the past decades. This is partly shown by the fact that of the women between twenty and twenty-one were enrolled in college, while in 1981, 30 percent of the women between twenty and twenty-one were enrolled in college.
To evaluate the argument above, it would be most useful to compare 1959 and 1981 with regard to which of the following characteristics?
(A) The percentage of women between twenty and twenty-one who were not enrolled in college
(B) The percentage of women between twenty and twenty-five who graduated from college
(C) The percentage of women who, after attending college, entered highly paid professions
(D) The percentage of men between twenty and twenty-one who were enrolled in college
(E) The percentage of men who graduated from high school

THE KEY IS D。

为啥是D呢？20-21岁男生中有多少比例的男生录取了，与女生的比例之间有啥关系啊？

男生在20-21男生中的比例低，这个不是男生占总的人数的百分比（20-21），所以也不能说明总的女生的录取比例高了？

晕了，今天状态不佳，脑袋反映不过来了。。

GMAT以前最爱出这种题，

A、B两部分：A数量增加，A比例增加； A不变，B减小，A比例还是增加。

两种情况：A的比例都增加

偶倒，lz可能理解错了。。。

The percentage of men between twenty and twenty-one （20到21岁男性的比例）是说20到21岁入学的男生占所有20到21岁学生的比例，不是20到21岁入学男生占所有入学男生的比例。
