continuing (set 3 of 3) ...I had posted some questions earlier and got prompt answers from mahr90. Thank you very much. My exam is in 1 month and my anxiety is starting to kick in. I'm trying to post all the questions that were wrong in my first NBME attempt. It would be very grateful if someone could take a crack at these questions.

I've uploaded album of 21 questions here (41-61):
