The Death of Math

[Einstein]

False, because both answers 1 and 2 cannot be correct.The question wasn't "If A > C and B > C, what is true about A and B?"

wherefore the correct answer would be "A > B or  A < B."

And, though I was jesting, 

I do  believe it best to admit the truth

when there is something I either don't or cannot know.

You are correct in that the answers can't be correct at the same time. But individually each answer satisfies the original query. That is why I listed them all.

Actually, while one need only know

both answers 1 and 2 cannot be correct

to rule out the possibility that 1 through 3 are all correct, the fact that any of the answers could be true rules out all but the last answer, i.e. if there is no way for one to know; then s/he doesn't know.
And that's only hard for a genius to admit, no?
