Question: In a certain society any time somebody commits a serious crime they must be shot at twice with a 6 bullet revolver. The revolver only has two bullets in it though, both of them right next to each other. They spin the revolver once and shoot the gun. If there was no bullet in that chamber they give the prisoner the option to either spin the chamber again or just shoot again. If the first shot is a blank, should the prisoner ask for the revolver to be spun or should they choose that it be shot again?

Question: I can fly like a bird not in the sky which can always swim and always dry. I say goodbye at night and morning hi I'm part of you what am I? I follow and lead as you pass. Dress yourself in black my darkness lasts. I flee the light but without the sun. Your view of me would be gone.
