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.

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.
(B) While private schools are typically very expensive, attendance of public school is free for the residents of the county.
(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.
(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.
(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 really doubt the OA E as per the above discussion. For given reasons in E, public schools do not offer an incentive to go to school. How does it weaken the conclusion? Apparently private schools are better.

I chose E. Out of remaining 70% who want to pursue college study, 65% got in the college. The percentage is higher than the 90% of private school. I can't find any other options that would work better than E though.

If E) is true it means 65/70 % students go to college from public school which is better than private school

the conclusion is: 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.

I don't think it's E.

This is true, but what this tells me is that the premise is wrong to start with. It weakens the premise, but not the conclusion of why parents should send the kids to private rather than public.

Correct?

(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.

I went with D at first, but I can see why it's wrong: It's comparing acceptances to attendance.

IMO E because the answer choice shows that the causal relation can be partially due to correlation rather than causation. Since students in the rural area choose not to go to college then it breaks the causal relationship that going to public causes leads to less likely to attend college.

I picked "D" first, but "E" has the best argument to weaken the conclusion.
