Hi,

I have couple of doubts in few of the sample questions on PMP. Would be great if you all can pour in your opinions with "explanations".  I am appearing for 4th edition in Sep'09.

Q1. WHich of the below acivity has max. slack/float?

A  LS=0   ES=10
B  LS=39  ES=31
C  LS=6   ES=0
D  LS=2   ES=0
 
Doubt: In option A, LS-ES= -10 and in B, its 39-31=8. My doubt is whether to ignore (-) in option A or B is correct option?
