Question Stats:

67% (02:19) correct 33% (01:33) wrong based on 161 sessions
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.


Why not D?

We have to weaken the argument that is "if my child goes to private school, it is very likely that he will be accepted to college" In order to increase the likeness of acceptance , private schools are better than those of public."

E clearly states that "no, case is different here. Public school students do not continue to college education because they choose to be farmers. There is nothing wrong with the public school. But the types of students attending the two types of schools are different"

D is not a strong weakener as E.Because not that private school in itself causes college attendance...

Bit confused on this one.. the questions stems says - 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.

Isn't D increasing the likelihood that their children will be able to attend college ?

Why not D?


D is not a weakner. Because a it disapprove the thought said in the question stem. As per this choice the statistical reports given in the question stem 90% and 65% seems to be wrong.

It says
Sending Children Public school -----> Then likelihood to attend College is very less.

To weaken the conclusion the answer choice should give some other reason to say "likelihood to attend College is very less"

Not necessarily. The argument states that there is a correlation between public school numbers and college intake numbers. The conclusion implies that public school CAUSES the lower admission rates in colleges. Now, to weaken that conclusion, you do not really need some other reason to say that the "likelihood to attend college is very less". You could also weaken by saying that the likelihood is the same, but not all students apply to colleges (and choose to be farmers instead).

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.
Its more acting like a strengthener rather than weakener

B. While private schools are typically very expensive, attendance of public school is free for the residents of the county.
Doesn't suggest how free attendance in public schools will increase likelihood of a student to attend graduation

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 one is sarcastic. Though public schools receive financial aid, still % of students going college is less. So, there must be some other problem which financial Aid cant solve.

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.

Lets say likelihood of getting admission in college through private school is 80% and likelihood of getting admission through public school is 60%. Now I introduce sports and athletic activities in public school which may increase likelihood by 5% and so likelihood increased to 65% from public school, but still chances are less. Therefore, D is not a strong weakener.

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.

Do whatever you want, but we are not interested to go college because we like farming. Such scenario leaves no scope for interpretation of the trend and so, no scope for any recommendation. Here argument fells apart and authors recommendation appears unjustified.

All of the above explanations say that option D is not a weakener enough. But the conclusion says, " if parents wants to increase the likelihood..." , its not saying that the likelihood should be more that private schools. Option D comfortably increases the likelihood of public school students and the feature is exclusive to public schools.

As is usually suggested, I stuck myself to the conclusion, "increase the likelihood". Can someone please point out an error in my reasoning?

Hello nitin

Yes, D strengthens the conclusion, not weakens.

The gut of this question is to test you how to use comparison correctly in an argument. Think about "increase the likelihood" this way:
* more percentage = more likelihood
* less percentage = less likelihood

That's the basic idea. The author mentions percentage of graduates of private high schools go to college > percentage of graduates of public high schools go to college. It means 90% > 65%, so private school increases the likelihood of students to go to college.

We can translate D into: Although public schools did a lot of additional activities in order to increase the likelihood of their students go to college, the percentage of their students go to college is still smaller than that of private schools. It means private schools indeed are better than public schools. Thus, D strengthens the argument, not weakens.

Hope it helps.
