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

Classic example of the "scope shift".

Conclusion argues that proportion of women among the students enrolled has increased. It means that there were more women on campus (women/all students)

Evidence used is that of proportion of women enrolled among 20-21 year old females. It's very different proportion: (women enrolled)/(all women between 20-21).

To reconcile the evidence with the desired conclusion we should also examine the same proportion for men - (D)

twenty-one were enrolled in college, while in 1981, 30 percent of the women between twenty and twenty-one
were enrolled in college.

P1 - Prop of Women enrolled has gone up in past decaded
P2 - 1959 - 11% (20-21) while 1981 - 30% (20-21)
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 - Out of Scope
(B) The percentage of women between twenty and twenty-five who graduated from college - Out of Scope
(C) The percentage of women who, after attending college, entered highly paid professions - Irrelevant
(D) The percentage of men between twenty and twenty-one who were enrolled in college - Irrelevant (Women are the only ones considered in this argument)
(E) The percentage of men who graduated from high school - the first line says proportion of women AMONG students (Men and Women) - BEST ANSWER

(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

Explain your answer.


My take is A.

The very first sentence is not a premise but a conclusion of the stimulus. The percentage of women | among students enrolled in higher education programs | has increased over the past decades. So the percentage of women has increased, is the conclusion. This conclusion is followed by a supporting premise that those between ages twenty and twenty-one (NICE!!!! :wink: ) were, in '59 - 11% and in '81 - 30%. Now to substantiate the claim and properly support the given premise, we need to know what the population of women of that given particular age group was at both the times. This can be understood only from option A. Just because a percentage was given in the stimulus doesn't mean the claim stands strong. We need to know the wholesome to be able to compare accurately. Or some means to get to the perfect wholesome. Option A alone gives the relevant information.

Answer : Option D

Men in College + Women in College : 100 %

For the % enrolment of women to go up , % enrolment of men has to reduce.

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.

Explain your answer.


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.
answer D.

I am not sure if my explanation would be any better than the ones given above...

An implicit assumption that I am making here is that the age group being referred to is 20-21

1) The argument states that the proportion of women among students enrolled in college has increased. This means that the ratio W/(W+M) has increased.
2) 1959: Of the women between 20-21, only 11% were enrolled in college. Assuming the number of women between 20-21 to be 100, then W here comes out to be 11
3) 1981: Of the women between 20-21, only 30% were enrolled in college. W here comes out to be 30

30/(30+M) > 11/(11+M) -> To evaluate this, all we need to know is M. Hence D.

(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"

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!

(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??


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.

(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....

I initially thought about A.
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.

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 :).

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?
