Hi jeremy, I agree with E. First, you have to realize that if (-1)*x = 1, then x=-1
Then, just plug in -1 in each of I, II and III and you will get an integer.
I) -1 / 2+(-1) = -1/1 = -1 --> this is an integer
II) -1-2 / 3 = -3/3 = -1 --> this is an integer
III) -1+1 / 4 = 0/4 = 0 --> this is an integer

Agree with this. The hardest part of the problem is the crappy Kaplan cd making the equation look stupid. To me, it looks like [(-1)^x]x=1, which means nothing at all. So if that threw you off, don't worry - Kaplan is often nothing like the real test and you won't have the problem on the real exam.

am I being transparent about my feelings for Kaplan? I've never been too diplomatic....

What I am hearing lately from people who did the GMAT that Kaplan's questions don't look like anything GMAT!!

Their questions are 'difficult' but that doesn't mean they cover the spirit of GMAT's questions.

Princeton Review contains a lot of errors and mistakes. Barron's sucks......and so on.

What's going on guys? An input from those who did the exam would be great. What do you think Ian?
