According to a recent research study, more than 90% percent of graduates of private high schools in a certain county continue their education in college. By contrast, only 65% of graduates of public high schools subsequently pursue college education. Therefore, if parents in the county wish to increase the likelihood that their children will attend college, they should send them to private rather than public schools.

conclusion: if parents in the county wish to increase the likelihood that their children will attend college, they should send them to private rather than public schools.


Which of the following statements would most seriously weaken the argument above?

(A) Graduates of private schools typically score higher on standardized tests and other tests of academic achievement.
this definitely strengthens.

(B) While private schools are typically very expensive, attendance of public school is free for the residents of the county.
completely out of scope because its the enrollment into colleges due to education that is to be attacked, not the expense.

(C) In comparison with graduates of private schools, a substantially greater proportion of public school graduates receive need-based financial aid for their college education.
this is a good competitor to (d), can be considered.

(D) In comparison with private schools, public schools provide more opportunities for student involvement in sports and other athletic activities, which almost always increase the likelihood of students’ acceptance to colleges.
this option does just about what you need, weakens the private schools and upgrades the public schools.

(E) Since most public schools are located in rural areas of the county populated primarily by farmers, nearly 30% of students from public high schools choose to pursue farming occupations rather than apply to colleges.
strengthens again because thats the reason why students from public schools DONT go to colleges.

The argument concludes that children are more likely to attend college if they are
sent to private high schools instead of public high schools. The basis for this
claim is the higher percentage of graduates of private schools pursuing college
education. It is assumed that public schools are inferior to private schools as a
training ground for college. Any statement that provides an alternate explanation
for the fact that public school graduates attend college at lower rates than private
school graduates would weaken the argument.
Another way to interpret this question involves the concepts of correlation and
causation. The argument’s premise states that private school attendance (vs.
public school attendance) is highly correlated with college attendance. The
conclusion of the argument is essentially that private school attendance CAUSES
college attendance (and therefore, parents ought to send their children to private
schools to ensure eventual college attendance). This conclusion depends on the
assumption that the causation does NOT work the other way – in other words,
that “readiness or desire to attend college” does not influence the choice of public
or private school. Any evidence that readiness or desire to attend college DOES
influence the choice of public or private school will weaken the argument.
(A) While higher test scores might increase students' chances of admission to
college, they are unrelated to whether students will actually attend college. Even
if one could prove that earning higher test scores makes a student more likely to
attend college, this statement would not weaken the argument, but rather
strengthen it.
(B) Since the conclusion centers on the likelihood of attending college, economic
and financial considerations are outside the scope of the argument.
(C) Since the amount of need-based aid is not directly related to whether a
student will attend college, this statement is outside the scope of the argument.
(D) While better athletic opportunities could increase students’ chances of
admission to college, they are unrelated to whether students will actually attend
college. Also, even though the advantages of public school mentioned in this
statement were taken into account by the study, the proportion of graduates of
public schools attending colleges remains substantially lower than the proportion
of graduates of private schools.
(E) CORRECT. This answer choice demonstrates that the difference in the
percentage of graduates attending colleges stems not from any advantage
provided by private schools but from the fact that a subset of the graduates of
public high schools simply choose to pursue a different career path. In other
words, 30% of the graduates of public schools voluntarily choose not to pursue a
college education. Yet 65% - out of the 70% of graduates remaining - end up in
colleges. This statement indicates extremely high college matriculation rates for
students who want to attend college after graduation from public high schools.
Using the concepts of correlation and causation, this answer choice provides the
alternative causation for the correlation observed. In other words, "desire to
attend college" is ALREADY lower in the rural areas where public schools
happen to be located. According to this evidence, attendance at private or public
school is the effect, not the cause, of "desire to attend college."

E is correct, something else is the reason for Student for public school not going to college.

I still feel its D ... acc. to E .. student might change their mind and continue education rather than get into farming ... so E strengthens the argument ..

I choose D and here is my reasoning if someone can help me understand the flaw in it :

The conclusion of the argument is : if parents in the county wish to increase the likelihood that their children will attend college, they should send them to private rather than public schools.

Clearly, if an answer choice provides an alternate cause to not send the kids to private schools but instead to public schools in order to increase the likelihood of being accepted in college then it will be the correct answer.

IMO, choice D weakens perfectly the argument.
D) In comparison with private schools, public schools provide more opportunities for student involvement in sports and other athletic activities, which almost always increase the likelihood of students’ acceptance to colleges.

In the other hand, choice E, which is the correct answer as per MGMAT, is irrelevant because it reduces the scope to rural areas and as a matter of fact, the argument didn't discuss neither rural nor urban areas.

Thanks in advance.

According to a recent research study, more than 90% percent [#permalink] New post 20 Jul 2014, 23:57
I am confused with E. Is it not a strengthener..!!!!

E) Since most public schools are located in rural areas of the county populated primarily by farmers, nearly 30% of students from public high schools choose to pursue farming occupations rather than apply to colleges.

I mean the statement is saying that since public schools are near rural areas students in school are choosing farming as occupation. ie is the public schools are persuading students not to go college.

So, yes parents should not send the students to public if they want them to go to college......

please clear this confusion.....KUDOS for the best explanation...

D. doesn't add any new information, the promised advantage is undermined by statistic finding.(If it is a plan in the future, however, this choice can make sense)

E. states that, for public school, you should not count 30 students who do not intend to persue college in the first place. So 65 out of 70 is the actual public school acceptance rate.

The "best chance" for getting into school is based on numbers of people who actually apply to school. Choice E tells us that 30% of public school kids aren't even trying to get into school, so almost all of those who do want to go are getting in. That's why it weakens the argument.
Choice D, which I almost chose, talks about factors that public schools have over private schools. But these factors are already accounted for when talking about the respective acceptance rates.

According to a recent research study, more than 90% percent [#permalink] New post 02 Sep 2014, 04:46
IMO E.
90 percent of students graduating from private high school attend colledge
65 percent of those graduating from public high school attend college

Conclusion: parents should send their children to private school to increase the likelihood to attend colledge.

How to weaken this argument?

We need to find an answer that compare the public school with the private school and shows that students from public school will have chance to attend colledge not less than those from private school. only E meets these requirements so E is correct Ans.

Hope it helps!
