When looking at these relationships, it's difficult for me to determine which part of the statement is the sufficient condition and which is the necessary condition. As a result I continually fall for "the oldest trick in the book". Can anybody recommend a method for making this distinction? As of right now I feel totally comfortable reading Muriel's passage and extracting either G→V or V→G. #help

The question stem and answer choices were written differently in "Must Be True Questions Problem Set 5". The correct answer choice was "A" in the problem set, but is "C" in this explanation video. Was the link to this video a mistake? #help

I'm all set, but thanks for being so considerate.

I'm shooting for a 173 or higher. If you start a study group, I'd like to join. If there are too many people we could also separate into groups!
