You and a your friend are trapped in a room. There are two exists (a+b). a) One exist leads to a roaring Inferno with a thin bridge crossing to the other side, but there is a risk that it will fall. b) The other lead to lions which have been satrved for 2 months, so they will eat you and your friend on the spot. Which exist is the safest for you and your friend?
B is the safest. Taking exist A might gurantee your saftey but not your friend as it will probaby fall under your weight. On the other hand the lion have been starved for two months which probably means they are dead.
