The statements above, if true, best support which of the following conclusions?
(A) Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.
(B) 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.
(C) 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.
(D) 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.
(E) 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. Student of e-GMAT here. I used their process to come up with the correct answer. However, it definitely took me over the 2 min mark (at around 3 mins and 30 seconds) and this was difficult due to its tricky wording. Nevertheless, here's my process. Conclusion: MOST students (not all) with an IQ of 120+ and ALL students with 150+ who apply to one or more Ivy League universities get accepted to at least one Ivy League university. Phew...kinda long, but makes a lot of sense. The only premise we have to work with is that TN Highschool has students with IQs of over 120. Which means that if these students apply to 1+ Ivy league universities, most of them are likely to get into at least one of them. Basic pre-thinking: I won't lie here, but this was somewhat challenging for me. I came up with some flimsy assumptions in this. I'd love to see what you guys think about them. - IQ is the only factor required here for university admissions with 150+ scores - Students are likely to apply to Ivy league university. (I quickly realised that this was a false assumption and scratched it off). Alright! With some pre-thinking, I at least had a better idea of the argument, so I could move onto the answer choices. A. This does not have to be true. Some students may not have applied to an Ivy league university (or any university to begin with). Out. B. Not necessarily true. What if IQ goes down with age? I was great at tennis 10 years ago as a kid, but now I absolutely suck at it (even when playing with a 12 year old). No where in the argument does it state that IQ remains stable with age. C. Yeah. This seems right. D. Well maybe. Let's say that there are 100 students at this school. 99 students decided to start working after high school. The remaining student applied to only one Ivy league university and his score happened to be 125. Although it is likely that he'll get accepted, it is not certain that he will. E. She could have applied but decided not to go. C is the right choice. I definitely struggled with B and D. First in comprehending what they were saying and then in thinking of cases where the statements could fall apart. Hope this thorough breakdown of my process helps others. Hi, Amazing job here! You reasons for rejecting all the four incorrect choices are right on the mark. It is very encouraging to see this since even though a lot of students do mark the correct choice but they do not reject the incorrect choices for valid reasons. However, that is not the case with you. Good job! I just want to clarify one thing in the prethinking part. When you do prethinking for inference/conclusion questions, you need to prethink the inference, not the assumptions. For all other questions (strengthen, weaken, evaluate etc), you need to prethink assumptions but not in the case of inference questions. In inference questions, you need to prethink the inferences possible. So, in this questions, you might have done prethinking by understanding the information as below: 1. First thing that comes out is that the 2nd statement is only about those students who apply to at least one Ivy league university. Therefore, any inference which talks about students who did not apply to Ivy league universities is straight out of the way. (read point 2 for an exception to this) 2. Second thing is that Everyone from TN has IQ over 120. Now, one thing we can easily infer from this statement is that anyone studying at Ivy league who had an IQ below 120 when joining the university cannot be a student of TN. Isn't it? So, you have arrived at one possible inference just from the first statement of the passage. Now, you can also arrive at another possible inference by combining statements 1 and 2: If all the students from TN schools apply to Ivy league schools, most of them would be accepted to at least one of them. (Here we are combining the information that every student from TN has IQ over 120 and most students with IQ over 120 gets accepted to at least one of the Ivy league universities.) Thanks, Chiranjeev

Thanks for your explanation. You said that we know nothing about his IQ, but from the question, we have already known that he must have IQ of over 120. Furthermore, "most students with an IQ of over 120...are accepted...". So I infer that among all TN students who applied to Ivy League uni., there will be at leat one accepted.
For the OA C, I just wonder that "it is possible for him or her to have graduated from TopNotch High School." is not a good conclusion (I donot say that it's wrong) because he or she can be from any high school in the world.
Above is my few thoughts. Correct me if I'm wrong. Again, thanks guy!
About the IQ, we have to say that his IQ is 150+ in order to be sure that a student is accepted, because if his IQ is only 120+, his chances are high but we ARE NOT sure that he'll be accepted. Most students with an IQ of over 120 who apply to one or more Ivy League universities are accepted to at least one of them. About this part: Furthermore, "most students with an IQ of over 120...are accepted...". So I infer that among all TN students who applied to Ivy League uni., there will be at leat one accepted.<== we cannot say. If only ONE 120 IQ student applies, we can't say that he will be accepted. About this part: For the OA C, I just wonder that "it is possible for him or her to have graduated from TopNotch High School." is not a good conclusion (I donot say that it's wrong) because he or she can be from any high school in the world. Yes you're correct, that's why we read "it's possible for him (...)" Hope I've explained myself well

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.
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.
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.

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.

(C) 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. ya .. that'spossible CORRECT.
(D) 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. MOST DO GET ADMISSION ... BUT CAN'T GENERALISE TO ALL
(E) 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.WE are not talking of school but university.....

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.

options C and D were strong contenders.
But in choice D , we are told that "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.".
It may be/may not be because, graduates from top notch schools have IQ over 120 (may be greater than 150 or less than 150) . But in Premise we were told that "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. " Hence incorrect.
Choice C is correct.

Easily C, just fact check supports it. A) stimullus says OVER 150, score 150 is not mentioned B) he/she could have attended then was expelled out of school or ets .... D) it says Most of 120s, so its not sufficient to support this claim E) again it should be over 150, not 150 itself

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 a ll students with an I Q 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? (A) Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school. This is never said in the above argument.Only who have applied are mostly selected.We do not have any information about whether graduates of TopNOtch Schools even apply to Ivys Yes Ecery graduate of TN has a IQ of 120+ but it not told that anyone of the graduates applied to Ivys. May be some applied, may be none applied.. (B) 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. No information provided about people who are NOT graduates of top notch high schools.A person with IQ<100 could have been a student of top notch high school and left the school and graduated from some other school. (C) 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. Yes, it is possible.The information in the above argument supports this statement.This statement is not making a definite claim.These option just tells us that the graduates of TN with IQ of 130 may have applied to Ivys or is eligible to apply. (D) 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. No not necessarily true. The argument states that Most students with an IQ of over 120 and a ll students with an I Q of over 150 who apply to one or more Ivy League universities are accepted to at least one of them. .It is no where stated that the High School graduated even apply to Ivy universities. (E) 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. Not true. Most students do get selected .He might have applied but did not get selected.

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?
a) Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.What if he/she had not applied to an ivy league in the first place.
b) 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.That person could very well have been a student of TN HS but would not have graduated from TN HS. What if a student studied in TN HS but was not allowed to graduate from TN HS because of TN HS's ridiculously high standards? That student could have moved to some other school and passed that new school's graduation exam to graduate. So this option is not entirely true.
c) 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."possible". Nice balance in the statement. Keep this aside.
d) 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. Maybe there are no graduates with an IQ of 150+ and the stem says that most graduates with an IQ of over 120 get admitted. This means that all those from TN HS may not have got into an ivy league.
e) 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 stem talks about students with an IQ of *over* 150 getting into anyone of the ivy league he/she may apply to. This option talks about someone with an IQ of exactly 150. So this option talks about the 130-150 IQ graduates and these *most* not *all* of these graduates get into ivy leagues. This option is hence an extreme one.

AmoyV, what is wrong with B? It is mentioned in the premise that every student who has graduated from TopNotch school has an IQ of over 120, so if a student who has an iq of less than 100... Then he can't be a student of TN HS and that is what B says! Please correct me if i'm wrong

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. Can anyone guide why not A? NEGATE: NOT Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school. (however we did not take the consideration of whether he applied or not. but then why the word "accepted")

Are you applying the negation technique to it? That works for assumption questions only.

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. We don't know if every graduate with an IQ of 150 applies to Ivy-League schools2]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. Graduates of TopNotch are the relevant population.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. Since the stimulus says that most graduates of TopNotch who have an IQ above 120 and apply to Ivy-League schools get in, this is the best answer choice.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. We don't have enough information to say this. 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. We are discussing TopNotch high-school graduates.

ssriva2 wrote: yes,I was applying negation technique! Is that not right?  The name of the technique is assumption negation technique (ANT). It is used for assumption questions only. The logic of using the technique is this: An assumption is a necessary missing premise. It is NECESSARY for the conclusion to hold. If the assumption is negated, the conclusion cannot hold. Hence, it is a check to see whether a statement is actually an assumption or not. Check out how to use the ANT here: http://www.veritasprep.com/blog/2013/03 ... -the-gmat/

what is the best approach to solve problems like these. I always find multiple options correct in these kind of questions and it is very diffucult to select correct one within 2 mins. Anybody can put down a sound approach to tackle problems like these ?? Thanks in advance.

Thanks in advance. In must be true questions, if you are not sure whether the statement must hold, try to find a case where it may not hold. Try to make it false within the scope of the information given in the argument. 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. For example, in option (B) above, B]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. Now try to make this false. Can we have a high school graduate with IQ 100 who could have been a student at TopNotch? The important point here is "could have been". Sure. Perhaps she graduated from another school but could have been a student here before that. So it needn't be true - it could be false. She could have been a student at TopNOtch. So this is not the answer.
