Morning!

I'm just beginning to study for the GMAT and have a very weak quant background. I answered this question correctly but it took me 5 minutes to do so. I need to find ways to save time, could you explain to me why you noted that "1) does not talk about x. Insufficient" ? It seems like you removed choice A quickly.

This is probably a terribly novice question but I'm a novice so, I hope you don't mind!

Cheers,
