Glad to help! Manhattan is a great source for questions, since most of them have already been answered by someone who works there already. I use their RC explanations frequently when I get stumped.
@Mellow_Z I don't recall if Manhattan uses "VIEWSTAMP" but if so, I didn't like that book. Wasn't really beneficial for me at all. I would stick with The LSAT Trainer for RC. Can't comment on Blueprint.
