标题: 一個讓我糾結的問題~~

155. 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

(D) The percentage of men between twenty and twenty-one who were enrolled in collegeD

(E) The percentage of men who graduated from high school

問題是: proportion of women among students 和 women between twenty and twenty-one enrolled in the colleague是不是指一個概念，也就是後面那一砣人代表了women among students?如果不是，那麽還有別的年齡段的比例不知道，就算知道了D也不行啊？？？
男生比例不是可以直接得出是89%和70%？還要D幹嘛？
這道題我做對啦，覺得D最像，可是後來再看的時候覺得所有答案都不靠譜。。。。

----
你所指的89%和70%是出了20-21之间的女生之外的college students 包括此年龄段外的男生和女生当然得不出同年龄段男生的比例

为了要证明The proportion of women among students enrolled in higher education programs has increased over the past decades，必须要知道同年龄段男生的入学数量。出了D以外的其他选项都是无关项且选D也符合evaluate题型的标准
