Question 2

A murderer is condemned to death. He has to choose among three rooms. The first is full of raging fires, the second is full of assassins with loaded guns, and the third is full of lions that haven’t eaten in 3 years. Which room is safest for him?

Self-study riddle convention (editorial): assume ordinary lions have had no food for three full years, and compare only the hazards described. Enter the safest room number.
