Looks like a DS question to me......Too lazy to solve....so went with A first thinking that
(Even though, my hunch was D initially - come on - Will the question assume that class has only Men and Women ? So Men % will be sufficient )
Yes-D is correct ,logically as well :D

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
Does it matter even- nonetheless a lucrative answer
(B) The percentage of women between twenty and twenty-five who graduated from college
We are not bothered about this group, if at all we would be interested in other than 20-21 enrolled group
(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
Sounds ok, lets keep it for now
(E) The percentage of men who graduated from high school
We are looking out for enrollment not graduated %ages- are not we

I could not understand the reasoning behind the answer.

Initially I was looking for something like other than 20-21 year woman %ages (or total women enrolled %ages) but then could not find so by elimination we have D (fills the position for the rest of the group)

stem talks about the proportion of WOMEN among STUDENTS,which includes MEN, so we couldn't say the women % is increasing or decreasing without comparing it with the relative % of men.

So I would go with D

We need to figure what is the %age of women in collage has gone up between 59 and 81
A,B,C,E provides no such information
So D is right even though it makes not much sense, but then we need to find a partial known fact

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

(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

Confused between A and D but marked A to my fate it is incorrect answer...can anyone explain what's wrong with A??

Hey Kotela,

IMO,

Choice 'A' - Doesn't add any additional information. The percentage of women between twenty and twenty-one who were not enrolled in college can be calculated from the Q stem.
11% of women enrolled implies 89% of women were not enrolled
and 30% of women enrolled implies 70% of women were not enrolled.

Also, notice in the Q stem "The proportion of women among students enrolled", 'among students' suggests we need data pertaining to both the genders.

HTH,
Cheers!

Hi kotela, choice A is the already existing choices because you just use 100% - the percentage of women between twenty and twenty-on who enrolled in college. So, this cannot help you evaluate anything.

In choice D, just image the pie include women and men. If the men are eaten partly (women part did not change), the overall volume of pie will decrease. Correspondingly, the percentage of women part in new smaller pie increase although the volume of women part did not increase at all. That why choice D is the correct one.

Info asked in A could be found out directly from stimulus. percent of women not enrolled in college in 1959 is 100-11 = 89 and in 1981 the figure is 100-30=70. so we already know this information from stimulus.

As far as D is concerned it helps in providing an information about proportion of women in college.

proportion of women in college = no of women / (no of women + no of men )

no of men enrolled in college could be determined if we know percentage of men enrolled in college. hence D provides this info.

Straight D. We need to know the percentage of men.

(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

ok....

Now I realize why answer should be D.

The conclusion is

The proportion of women among the total students who enrolled in colleges has increased.
'Among the total students who enrolled in colleges' includes ONLY the enrolled students.

The total number doesn't include the one who didn't enroll in a college.

Thus, in order to see whether the proportion has increased, you only need to consider the ones who enrolled.

This rules out A.

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.

(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)
