Critical Reasoning

Quick question: Do we even need the first premise (all investment bankers want MBA from Ivy league) to strengthen the argument with answer choice A.

Simply put: Phil --> Tuck (IVY). Therefore, Phil must be planning to be an investment banker. Answer choice A strengthen this argument without the first premise right?

Thanks

if GMAT is going to ask this type of question then probably non-native can't answer, as they like myslef have to struggle in forming out the realtionship between two used named...I think they should tell us Tuck school is part of that Ivy university.

Do I expect these type of terminolgy in real GMAT too ?

Phil = investment banker
Investment banker ---> MBA; Phil = MBA

The issue with the logic here is the assumption that since investment banker ---> MBA, that MBA ---> investment banker.

Something that STRENGTHENS that link (showing that ALL those who want an MBA are planning to become investment bankers) will be correct.

We tend to have problems with CR when we compare answer choices instead of spending more time with the argument up front. I encourage you not to look at the differences between the choices, and instead WRITE DOWN your interpretation of the argument, and the underlying logic/assumptions first, using them to predict the correct answer.

Notice how when we do this, it becomes obvious that A is correct.

I feel this is formal logic of LSAT, which is not tested on GMAT. Some experts said that. But I do not know what is formal logic of LSAT. If this is formal logic, we should not study.

e only those with mba degrees from ivy universities are fully qualified for careers as investment bankers

OA: Spoiler Code A

I received a PM asking me to comment.

All A's are B's = If A, then B.
Answer choice A: All who want an MBA from an Ivy League school are planning on a career as an investment banker.
This means that if someone wants an MBA from an Ivy League school, then he is planning on a career as an investment banker.
Thus, A supports the conclusion here: Since Phil wants an MBA from an Ivy League school, he must be planning on a career as an investment banker.

Only B's are A's = If A, then B.
Answer choice D: Only those planning on a career as an investment banker want an MBA from an Ivy League school.
This means that if someone wants an MBA from an Ivy League school, then he is planning on a career as an investment banker.
Thus, D supports the conclusion here: Since Phil wants an MBA from an Ivy League school, he must be planning on a career as an investment banker.

A and D are both correct here.
But I would ignore this question.
It is testing the sort of formal logic that comes up on the LSAT but not on the GMAT.
