All of the best comedians have had unhappy childhoods. Yet, many people who have had happy childhoods are good comedians, and some good comedians who have had miserably unhappy childhoods are happy adults.
If the statements in the passage are true, which one of the following CANNOT be true?
(A) The proportion of good comedians who had unhappy childhoods is greater than the proportion of the best comedians who did.
(B) Some good comedians have had unhappy childhoods and are unhappy adults.
(C) Most of the best comedians are happy adults.
(D) More good comedians have had unhappy childhoods than have had happy childhoods.
(E) The proportion of comedians who are happy adults is higher than the proportion who are unhappy adults.

I think it's A.

The passage states that ALL of the best comedians had unhappy childhoods and that SOME good comedians had happy childhoods.

Since the proportion of the best comedians who had unhappy childhoods is 100%, it is not possible for the proportion of good comedians with unhappy childhoods to be any higher.

IMO (A)

premise 1: All of the best comedians have had unhappy childhoods.
100% of the best comedians have unhappy childhoods.
Premise 2: Some of the good comedians have had miserably unhappy childhoods
Not 100% of the good comedians have unhappy childhoods

so the proportion of best comedians who had unhappy child hoods is > than good comedians

Are these type questions asked in GMAT? I am having a belief that these questions are out of scope for GMAT...

so the proportion of best comedians who had unhappy child hoods is > than good comedians


(A) is correct, but one small mistake in this reasoning.

"Some" literally means "at least one" and has no upper limit.

So, "some of the good comedians have had miserably unhappy childhoods" means that "at least one good comedian has had a miserably unhappy childhood". It's actually possible that ALL of them were miserably unhappy.

So, as Mschling pointed out, since 100% of the best were unhappy, it's impossible that a GREATER proportion of the good were unhappy, since there's no proportion greater than 100%.
