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 (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 155. The argument presents a substantial increase in the proportion of women between twenty and twenty-one who were enrolled in college as evidence that there was an increase in the proportion of higher education students who were women. This evidence would lack force if a similar increase in college enrollment had occurred among men. Choice D is therefore the best answer. Since percentages of men graduating from high school do not indicate the percentages enrolling in college that year, choice E is incorrect. Choices A, B, and C are incorrect because the information they refer to, being about women only, does not facilitate a comparison of women’s enrollment to men’s enrollment in higher education programs. 做的时候毫不犹豫选了A,因为其他的在第一时间就被排除掉了 看了答案,实在不明白为什么女性学生入学比例的提高要和男性比才行呢? 请各位不吝赐教!! |
