If a and b are integers, and |a| > |b|, is a · |b| < a – b?
1. a less than zero
2. ab greater than equal to zero
Would love to see explanation for this one. Can this be cracked in 2 min time?

I am not sure as to what exactly is the inequality, since formatting is messing up what you've written. Anyways, I would rewrite the inequality by dividing both sides by |b|.
Now a/|b| would be greater than 1 or less than -1 depending on a > 0 or a < 0. Similarly b/|b| = 1 or -1 depending upon the sign.

Is the answer E?
I just put in different values for a and b and arrived at that answer. I wish there were some elegant solution to this problem.
