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 by at least one of them.

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

Every graduate of TopNotch High School with an IQ of 150 has been accepted by at least one Ivy-League university.

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.

If a person has an IQ of 130 and is attending an Ivy-League university, it is possible for him or her to have graduated from TopNotch High School.

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.

If a high-school graduate has an IQ of 150 and is not attending an Ivy-League university, then he or she did not apply to one of them.

The question asks for the conclusion, not the argument. The conclusion is " 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. " I picked E even though I know it's wrong because the student could have simply chosen not to go to an Ivy league school, but the correct answer, C talks about the argument and conclusion. And why couldnt answer B be right as well?

Thanks a lot everyone!

It very well could be that someone with an IQ of over 150 chose NOT to apply to an Ivy. The stem says:...all students with an IQ of over 150 who apply....

(B) is not supported by the information in the passage. Someone with an IQ of less than 100 could have been a "student" at TopNotch High School, but he certainly did NOT graduate -- The stem talks about students who graduated from TopNotch high school have an IQ of over 120...We don't know anything about the IQ of students who attended the school.

Hope this helps.

B couldn't be right because a person having IQ <100 could have been a student at TopNotch School and then failed and went on to graduate from some other school. Thus, B is wrong.

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score.

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
