Where did you get this question from? It feels like a really good representation of an actual GMAT question

I simplified statement 1 down to v=w and then reasoned that i need to have w in order to know what v is. then choice c looks very attractive.

what am i missing here. I cant even see the trap let alone fall for it.

my wrong answer is c

qa is a how in the world is that possible?
statements 1 boils down to v=w but one woulld need w in order to see what v is. need to see the light on this one
