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.



Do not quite understand how E is correct.

Fact 1: 30% choose farming--y-- because they are based in rural area public school and choose farming
Fact 2: If they are sent to private school, they will pursue college

Fact1+ Fact2--- supports conclusion that why they should not be in public college(because public = farmers) and if sent to private= no farming(as private are not located in rural area)
I felt that E is strengthening. Expert help needed.


Prompt: 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.

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

The said 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.

Option A: Graduates of private schools typically score higher on standardized tests and other tests of academic achievement --> this only strengthens the above argument as if they want their kids to attend college, they should send them to private schools since students from private schools excel in standardized tests and other tests.

Option B: While private schools are typically very expensive, attendance of public school is free for the residents of the county --> argument is irrelevant because it talks about how education is inexpensive (free) in public schools and therefore more students in the county will attend them [ again, attending a public school doesn't guarantee anything + it doesn't strengthen the argument in question]

Option 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 --> more scholarships for public school graduates mean more graduates from public schools will be determined to get into college, but that's not happening according to the prompt and the option doesn't weaken the argument in question[/color]

Option 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 --> yeah, more students from private schools get into colleges for various reasons, so what? It only strengthens the argument (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) in question and doesn't weaken it, which is what the question has asked us to find out.

Option 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 --> Of course, if it's a county and it has a public school that's inexpensive, most of the people (farmers, essentially) of that county would sent their kids there and once those kids graduate from school, they would be more inclined to takeover their parents occupation rather than opting to go for further studies, which is why the argument in question (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) is weak [original question is to find the option that weakens the argument, remember?]

Hence option E is the right answer :)

Hope this helps :) If you're still confused, I kindly urge you to read logic guru's explanation too.

This is a good question !!
In my 2 cents,

Conclusion : 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.
Prem 1 : more than 90% percent of graduates of private high schools in a certain county continue their education in college.
Prem 2 : only 65% of graduates of public high schools subsequently pursue college education

A. Graduates of private schools typically score higher on standardized tests and other tests of academic achievement.
-- This information somehow strengthens the argument.

B. While private schools are typically very expensive, attendance of public school is free for the residents of the county.
-- This information has no bearing with the likelihood of children to apply for the college.

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 strange.Given that there are more aids available for students from public schools,still the number of students from public school attending colleges is lower than that from private school.

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 is irrelevance to the conclusion.It is about to increase the likelihood to apply for college,not to get accepted!!

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.
-- This option weakens the argument.It states that 30 percent of students from public school choose not to attend to college regardless of whatsoever condition.Hence,it is actually 60% out of 70% of students who choose to attend to colleges;this figure is greater that that of private school !!

Please feel free to advise if anything is wrong
Thanks :-D

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.

Type - weaken

The argument concludes that children are more likely to attend college if they aresent to private high schools instead of public high schools. The basis for thisclaim is the higher percentage of graduates of private schools pursuing collegeeducation. It is assumed that public schools are inferior to private schools as atraining ground for college. Any statement that provides an alternate explanationfor 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) Graduates of private schools typically score higher on standardized tests and other tests of academic achievement. - 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) While private schools are typically very expensive, attendance of public school is free for the residents of the county. -Since the conclusion centers on the likelihood of attending college, economic and financial considerations are outside the scope of the argument.

(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. -
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) 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. - 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) 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. - 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. - Correct


Answer E

Conclusion :- children are more likely to attend college if they are sent to private high schools instead of public high schools.

Weaken :- children are less likely to attend college if they are sent to private high schools instead of public high schools.

(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) It provides an alternate explanation for why fewer public school students go to college. take out the farmers, and the percentage of the remaining public school students going to college is actually higher than for private schools. As long as going to private school does not change a student's predetermined likelihood of going into farming, E totally destroys the argument.This answer choice also 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.

Hence choice E is correct and D is wrong.

Premise: Private -higher study more, Public- Higher study less
Conclusion: To be sent to Private school to increase the % for Public Sc.
Missing Info/Link: Students from Public sc. have the same will to pursue higher edu. as in Private sc. students
Option E clearly weakens the argument(Note option D: nothing has been said about eligibility or acceptance of students)

The main point 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.

A - The statement doesn't tell anything about tests. So, A is out.
B - We only focus on attendance rate of students who attend their college. We don't say anything about the cost. B is out.
C - Doesn't tell anything about acceptance rate. C is out.
D - The word "almost" made this statement wrong. It almost always increase the likelihood of students’ acceptance to colleges. This doesn't means it always increase the acceptance rate. D is out.
E - If this statement is true. So this is the reason why public high schools have lower rate than private high schools. Therefore, private's students may not have advantages from their private schools.
The answer is E.
