Yes this indeed is tough. Very nice question. Marked the wrong answer but I am convinced, thanks to seekmba & JenRugani, that C has to be the correct answer.
seekmba & JenRugani - Your help is highly appreciated. +1 done already. :)

The statements above, if true, best support which of the following conclusions?

1]Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.
2]If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.
3]If a person has an IQ of 130 and is attending an Ivy-League school, it is possible for him or her to have graduated from TopNotch High School.
4]At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.
5]If a high-school graduate has an IQ of 150 and is not attending an Ivy-League school, then he or she did not apply to one of them.


Responding to a pm:

The question isn't tough. You just need to analyze the words very carefully. It doesn't have any ambiguity.

Argument:
Everyone who graduates from topnotch high school has IQ > 120.
Most > 120 and all > 150 students who apply get accepted to at least one Ivy league university.

1]Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.
We don't know whether every graduate has applied so we cannot say that every graduate has been accepted.

2]If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.
All we know is that everyone who graduates from top notch has IQ > 120. It is possible that someone with IQ = 100 is a student of a top notch high school for a while but graduates from some other school.

3]If a person has an IQ of 130 and is attending an Ivy-League school, it is possible for him or her to have graduated from TopNotch High School.
This statement says that it is possible that an IQ = 130 Ivy league school student graduated from top notch high school. This is true. It is certainly possible. Mind you, it is not essential that an IQ 130 ivy league student must have graduated from a top notch school but it is certainly possible. Hence (C) is the answer.

4]At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.
Not necessary. It is possible that no student from top notch has IQ > 150 or even if there are students with IQ > 150, they may not have applied. We know that most students with IQ > 120 who apply get accepted but it is possible that all those who applied from top notch (and hence had IQ>120) got rejected. (Number of people who applied from top notch could be a very small % of the total number of people with IQ > 120 who applied)

5]If a high-school graduate has an IQ of 150 and is not attending an Ivy-League school, then he or she did not apply to one of them.
Again, if one has IQ > 150 and applies to Ivy league, one gets accepted. Whether one eventually attends the school or not is up to the individual. So a high school graduate with IQ > 150 could have applied (and would have been accepted) but may not be attending the school.

Answer (C)

I still can not understand why version D is not correct:
Everyone who has graduated from TopNotch High School has an intelligence quotient (IQ) of over 120. Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted to at least one of them.

1]Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.
2]If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.
3]If a person has an IQ of 130 and is attending an Ivy-League school, it is possible for him or her to have graduated from TopNotch High School.
4]At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.
5]If a high-school graduate has an IQ of 150 and is not attending an Ivy-League school, then he or she did not apply to one of them.

the argument is telling that all students from the school have IQ over 120, after it says that most students with IQ over 120 who apply to one or several Ive League schools get accepted to at least one of the schools.

Now the answer D tells exactly the same thing and can not find any contradiction between prompt and the answer.
If all students are over 120 and most of 120 who apply to the school get accepted at least one the schools.when at least one of the students from those of top Notch school who applied for sure will get accepted to the school.

I know that i am missing something but do not understand what i am missing.

As I said before, you have to read every word carefully. The framing of the question is a little tricky.

The argument says that "most students with IQ over 120 who apply to one or several Ive League schools get accepted to at least one of the schools." It doesn't talk about TopNotch school. Just that if 1000 students with IQ > 120 will apply to Ivy League univs. most will get accepted. Say, out of 1000, 900 will get accepted. 100 will get rejected.

Now option (D) talks about TopNotch school. All TopNotch students have IQ > 120. Perhaps there are 500 students in TOpNOtch. Say all of them have IQ less than 150. Do we know how many of them applied to Ivy League schools? No. Perhaps only 10 did. Is it possible that all 10 got rejected? Sure because of the 1000 students who applied, only 900 got accepted in at least one Ivy League Univ. Those 10 could easily have been a part of the 100. Hence it is possible that option (D) may not hold. Therefore, we cannot say that it must be true.

Always be very careful with options that twist the numbers slightly.
In this case the passage says : Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted by at least one of them.
Whenever you see words such as ONLY, MOST you should be doubly careful.
Most doesn't mean necessarily all. This is one reason why options like 4th can be eliminated.

Okay, this is how it goes.....

Since the passage contains information about both TopNotch High School graduates and those accepted by Ivy League universities, a valid conclusion must contain information that does not contradict either situation. In addition, a valid conclusion should be based directly on the information given in the passage. Be careful not to make unwarranted assumptions: for example, a person who attends a school does not necessary graduate from it, a person who graduates from high school does not necessarily apply to a university, and a person who is accepted by a university does not necessarily attend it.

(A) The passage states that every student with an IQ of 150 who applies to the Ivy League will be accepted by at least one of the universities. However, it is possible that a graduate of TopNotch High with an IQ of 150 did not apply, and thereby was not accepted, to any of the schools. Hence, this conclusion is not valid.

(B) The passage states that every graduate of TopNotch High has an IQ of over 120. The conclusion only states that the student is a high school graduate and that he has an IQ of less than 120. It does NOT state that he or she was a graduate of TopNotch High. It is possible, however, that after attending TopNotch High for a period of time, he or she graduated from another high school. If this is the case, the situation does not contradict the passage, but contradicts the conclusion (he or she was a student at TopNotch High). Hence, this conclusion is not valid.

(C) CORRECT. This choice presents a possibility, as opposed to a certainty: is it possible that a person with a 130 IQ and attending an Ivy League university previously graduated from TopNotch High School? This does fit the stated facts in the argument: TopNotch graduates all have IQs over 120, and it is possible for TopNotch graduates to gain acceptance to Ivy League universities.

(D) The conclusion states that most, but not necessarily all, of the graduates from TopNotch High with IQ of 120 who apply to the Ivy League are accepted by at least one of the schools. The conclusion, however, does not state positively that any of the TopNotch High graduates had an IQ of over 150. Hence, even if it is unlikely, it is possible that none of the TopNotch graduates had IQs of over 150, and, of the remaining graduates who applied to the Ivy League, none were accepted by an Ivy League university. This conclusion is thereby not valid.

(E) The passage states that any student with an IQ of 150 who applies to one or more Ivy League universities will be accepted by at least one of them. It is possible, however, that some of those who had applied and been accepted to an Ivy League university chose not to attend. Hence, this conclusion is not valid.

I am surprised that I picked the right answer for this CR. I picked (C)

My reasoning is below

Everyone who has graduated from TopNotch High School has an intelligence quotient (IQ) of over 120. Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted to at least one of them.

The statements above, if true, best support which of the following conclusions?

1]Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.
>>> Every graduate of TopNotch HS will get accepted only if everyone applies. A graduate can get an IQ of 150 but still decide not to apply.

2]If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.
>>> We are talking of students graduated from TopNotch High School and not students who were at TopNotch High School. It is quite possible that a student studied at TopNotch High School for few years and then changed HighSchool and got less than 100 when he or she graduated. He/she will still be called as someone who was student at TopNotch High School.

3]If a person has an IQ of 130 and is attending an Ivy-League school, it is possible for him or her to have graduated from TopNotch High School.
>>> THIS IS CORRECT.

4]At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.
>>> Not necessarily.

5]If a high-school graduate has an IQ of 150 and is not attending an Ivy-League school, then he or she did not apply to one of them.
>>> The premise says all students with an IQ of over 150 will get accepted. So we cannot say that a student who has an IQ of 150 will get accepted and that if he is not attending than that is because he did not apply.


I went for B. Thanks for the explanation. C sounds like a good answer since it has the phase " it is possible". It is a safe choice if I have to guess.

Everyone who has graduated from TopNotch High School has an [#permalink] New post 13 Aug 2014, 01:53
my explanation for the above;
i did choose c but had conflicts between b and c;
lets glance through the options once
1]Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.
talks about an IQ OF 150, not OVER 150. Since the argument states that top notch(TN) graduates with an IQ over 150 definitely make it if they apply. IQ = 150 will fall in the category of people with IQ>120. hence, this option falls apart.
2]If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.
hmmm, this got me thinking. if IQ<100, he/she COULD not have been a student at TN because every student who GRADUATED from TN has an IQ>120. we are not concerned about TN students in general. But this option did jitz me out for a while.
3]If a person has an IQ of 130 and is attending an Ivy-League school, it is possible for him or her to have graduated from TopNotch High School.
This one is worded absolutely perfectly, words like POSSIBLE and stuff are placed and used appropriately. In fact this does help in concluding the statements mentioned above.
4]At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.
lets say TN has only 1 student, he may have an IQ>120 for sure, or may be even over 150. But what is to be noticed is, he MAY make it to an IVY or may not make it to an IVY. what if that one student has an IQ >120, he applies and doesnt get through. The argument says most of the students above 120, not all students above 120.
5]If a high-school graduate has an IQ of 150 and is not attending an Ivy-League school, then he or she did not apply to one of them.
does it really matter if a high school graduate with an IQ of 150 doesn't make it to an IVY because he/she did not apply? i don't think this makes sense to me.
