Please post only one question per thread. Otherwise things can become pretty complicated when there are discussions on multiple questions.
Also, be sure to post the actual question. Not everyone has a copy of the OG13.
Finally, post your questions in either the Problem Solving forum or the Data Sufficiency forum.
Cheers,
Brent
Please someone should explain these questions for me.
