I have found that explanations for most of the gmatprep questions have already been post on the manhattan gmat forums. If you google the first five or so words of the question generally a link to a manhattan gmat thread will be one of the first results
Good advice! Particularly, write "site:manhattangmat.com" first (without the quotation marks), space, and then put the first few words in quotes.
For example, I would type into google:
site:manhattangmat.com "If Brian buys five pairs of shoes"
