INFERENCE Question 2 in CR

by nandy1984 » Tue Oct 11, 2011 4:57 pm
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.
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.

In the above problem i can eliminate (B) and (E) directly as they are not in the scope of the argument...Because
(B) talks about the students getting score less than 100....WRONG
(E) talks about the students who have not applied which is out of scope....WRONG
We are left with (A),(C),(D)
(A) "EVERY" student with an IQ of 150 is selected in the IVY...Which is wrong as the passage states "ALL students having score > 150" not "of 150" so (A) is WRONG
(C) is true as all the students from the TopNotch High school have a IQ > 120 ...so cannot ELIMINATE it.
(D) This also seem to be correct as the students from the TopNotch have IQ > 120 and one of the statements say that "Most of the students having IQ > 120 are selected atleast in one of the IVY league...

Can anyone help me in choosing the answer and the reason behind it....THANKS....

This is a tricky question, but IMO the answer is C.

A - This says every graduate of TNHS with an IQ of 150 has been accepted to at least 1 Ivy League school. We know that everyone with an IQ > 150 WHO APPLIES to an Ivy League school gets into at least 1. The argument says nothing about whether these graduates all applied or not. We can eliminate this.
B - This is a tempting answer choice. We know that the IQ of graduates of TNHS have to be > 120. This says that a high-school graduate with an IQ < 100 could not have been a student at TNHS. However, that person could have been a student at TNHS but graduated from a different HS. We can eliminate this.
C - The language is not very strong here. It simply says that if a person has an IQ of 130 and is attending an Ivy-League school, it's possible for him/her to have graduated from TNHS. We know all graduates have an IQ > 120 so that is fulfilled. We also know that most of those people with IQ > 120 get into an Ivy League school if they apply. So it's definitely possible for this to be true. This may be the correct answer.
D - This says that at least 1 graduate from TNHS who has applied to one Ivy League university has been accepted into one of them. This is tempting as well. But we know nothing about students at TNHS and where they applied. There could be no students that applied to any Ivy League schools. We can eliminate this because of the extreme language.
E - This says that graduates that have an IQ > 150 and isn't attending an Ivy League school, they didn't apply to them. The argument only says that the students with IQ > 150 that apply to Ivy League schools will get in - it doesn't say that they will necessarily go there. We can eliminate this.

I don't think C is the strongest answer choice possible, but it's the best of the group.

IMO: C

a: did not mention anything about whether they applied or not
b: out of scope
c: keep it
d: keep it
e: we do not know abt attending... out of scope

between c and d ==> the language of choice C which say "..... it is POSSIBLE for him/her to...." is a good reason to choose this
on the other hand, it is really tempting, but the use of word "at least in both side of the sentence is a bit suspicious :D

finally, i will go for C

I got your point..Its well explained i am clear about it now...The problem with me is i am able to eliminate 3 out of 5 answer but it takes me lot of time for me to decide on the last 2 choices...If there are any techniques of disecting them like you metioned the choice (C) is not very strong statement...Are there any other things we can look at...I am just trying to understand this will help all of us in answering them in more ordered way...LIKE:
1) First eliminate the answer which are OUT OF SCOPE....
2) Eliminate answers which are WEAKINING the above statements....
The first two are simple and we need not be cautious so we will end up with 2 choices now we need to see:
3) which choice is more close to the argument...As you said there is nothing told about the students of the school applying to the IVY..So unecessary correlations or conclusions....As rest of the passage talks about the scores students have achieved instead of the TNS students...Rather we need to select which are more generalized kind...

Sorry to make this post lengthy but it will help us...If u have some more points please feel free to add them...Thanks once again....
