Why is it not E? The question refers to "proportion of women among students enrolled" and not "proportion of women between 20 and 21 among students enrolled". D offers a more specific answer to a general question. Can someone please explain?

The key to this argument is: The proportion of women among students enrolled in higher education programs.

That is, we are comparing the proportion of women to men at colleges. The evidence used, however, is the percent of 20 -21 yrs. old females attending college over two time periods, 1959 and 1981. Even if more 20-21 yrs. old females are attending college in proportion to the overall population of females, that fact alone does not speak to the proportion of women to men in college. To illustrate: let's say in 1959, 20% of those attending college were women. In 1981 that number could fall to only 10%. This is not inconsistent with the increase in attendance amongst 20-21 yrs. old females. While their ranks may have swelled, perhaps there has been a drop off in the percentage of 18-19 or 25 and over.

Thus to evaluate the argument, we need to know how many men were enrolled in college. Therefore the answer is (D).

Hope that helps clear any confusion .

D in 1.28

when two percentages are given we need to know the total sample set in order to compare them.

Thank you for your response, but I still dont get it. Let us use your illustration above, but this time let it be for men. in 1959, 80% of those attending college were men. in 1981 that number could have increased to 90% (as females reduced to 10%). That increase could be among men of ANY age group. It could still be possible that the NUMBER of men between 20 and 21 could well have reduced and the numbers in other age groups, say 25 above could have increased. (D) does not help us hence. Answer E is more general; it helps us evaluate the WHOLE pool of men as against one age group which could have either increased or decreased. Am i missing something here?

Look at this as a part to whole equation. We cannot say that the proportion of women has increased unless we have either a ratio, or a whole amount to compare to. D fills in the gap.

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

I could not understand the reasoning behind the answer.

1959:
Total number of students enrolled=100
Women (20-21): 11
Men: 0
Obviously then, Women NOT(20-21): 89

Thus, proportion of women enrolled in 1959=100%

1981:
Total number of students enrolled=100
Women (20-21): 30
Men: 70
Obviously then, Women NOT(20-21): 0
Thus, proportion of women enrolled in 1981=30%

Thus, the proportion of woman in total students decreased from 1959 to 1981.

1959:
Total number of students enrolled=100
Women (20-21): 11
Men: 89
Obviously then, Women NOT(20-21): 0

Thus, proportion of women enrolled in 1959=11%

1981:
Total number of students enrolled=100
Women (20-21): 30
Men: 0
Obviously then, Women NOT(20-21): 70
Thus, proportion of women enrolled in 1981=100%

Thus, the proportion of woman in total students increased from 1959 to 1981.

Conclusion:
If we know what percent of men were enrolled in 1959 and 1981, we can exactly find the proportion of women among the students enrolled.

Ans: "D"

Although I agree that D is the best choice here. But I don't agree with the explanation that of total 100 students enrolled in the class, 11 women enrolled and 0 men enrolled. Who are these rest of the 89 people enrolled in the class? kids? animals?

oops, Remember, premise says 11% of overall women (20-21 yrs) were enrolled, so the remaining 89% of the 20-21 yrs women were not enrolled(it is not about men, not even 100 students exist college)

-option D would be right if the premise would say '11% of enrolled students were women (20-21 yrs)'
but there is no option to determine the proportion of women (20-21) to men (20-21)

I could not understand the reasoning behind the answer.

this question has nothing to do with calculations or anything of that sort.
If there are a particular number of students in a class(obviously only 2 groups- boys and girls) , then the number of girls in the class depends on the
number of boys, and vice versa. Now since we are concerned with only one age group (20-21) , Option D is the clear winner.

Time taken should be around 30-40 sec.

read the premise again, 11% of the (women btn 20-21 yrs) were enrolled in college, so remaining 89% of the (women btn 20-21 yrs) weren't enrolled

what we are evaluating is whether the proportion of women among students enrolled has increased over the past decades. To know that proportion, we need the number of men among students enrolled and the number of women among students enrolled.

the number of women among students enrolled is given by the premises. So we are only missing the number of men among students enrolled, which is given by option D.

to answer this question correctly we must have information on percentage of men between twenty and twenty-one enrolled in college in the two period of 1959 and 1981.if the percentage of men dropped then surely the percentage enrollment of females is going to increase

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.
The proportion of women of age 20-21 has increased from 1950s to 1980s to evaluate this we need ratio or percentage of men .There ic chance that number of men enrolled decreased.

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 collegeComparison is b/w the women among the students enrolled and the men among the students enrolled.Those who do did not enroll are irrelevant to the argument.
(B) The percentage of women between twenty and twenty-five who graduated from collegeAge group changed.hence not comapring parallel things
(C) The percentage of women who, after attending college, entered highly paid professionsirrelevant
(D) The percentage of men between twenty and twenty-one who were enrolled in collegeThis can clearly evaluate whether the proportion has increased or is it an assumption.
(E) The percentage of men who graduated from high school.% of men who graduated is nt the issue.The matter of question is the students who enrolled.

To compare the proportion of women among students enrolled in higher education programs it would be best to compare 1959 to 1981 wiht regard to the number of men among the students.

My reasoning is this - the question speaks of proportion, and so I looked that word up and it said that proportion means comparison between similar items based on measurement or size of different parts of a whole.
Hence, I chose 'D', since women from an age group can be compared with men in that same age group (if we are talking of proportion).
I may be wrong though. Please comment.
