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 in 1959, only 11 percent 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（D）
(E) The percentage of men who graduated from high school
这是大全GMAT练习17中的第16题. 给出的答案是D
我认为D不对, 或者是D有歧义
D指的是 1.男孩子在接受高级教育的人中所占的比重, 还是
2.接受高级教育的男孩子占男孩子的比重
如果是后者, 则该选项不正确.
请大家发表看法因为：20-21岁的女性中，1959年有11%的女性读大学，1981年有30%
所以：受高等教育学生中，女性的比例上升。
D：20-21岁的男性中，读大学的人的比例
解释： 男性 女性
总人数 读大学 总人数 读大学
1959年 100 20 100 11 女性占学生比例=35.5%
1981年 200 100 200 60 女性占学生比例=37.5% （上升）
150 女性占学生比例=28.6% （下降）
