It is with great regret that we announce we will no longer be able to maintain public discussions of problems from the Official Guide books. GMAC has requested that all companies and online forums not post questions from copyrighted materials that GMAC sells to the general public. As it would be extremely difficult (if not impossible!) to discuss questions without the full question text, we have decided to suspend discussion of OG questions entirely, effective immediately.

As such, please don't post any more OG questions in this or any thread on the ManhattanGMAT forum.

We are very sorry for the serious inconvenience this causes you in your study; we very much wish we could still help you with these questions. However, we must comply with GMAC's request.
