Rail
A group of children play outside, and there are two pieces of rail in that place, one is being still used, one has already been stopped using. Only one child chooses to play on the rail stopped using, its children are all still playing on the rail that is used. Very unfortunately, the train has come. (and the natural one have a lot of children's above, still go on the rail that is used) . And you are standing by the switching over device of the rail, so you can let the train transfer to the rail stopped using. In that case you can rescue most children, but that child in stopping using the rail will be died. What shall you do?
It is said most people will choose to rescue more persons, in other words, sacrifice that child playing in stopping using the rail. But this draws another question again: That chooses the child who stops using the rail to obviously make the correct decision, choose the safe place after breaking away from his friend, but his friends are played in the place that plays by the ignorant choice. Why make correct people of choice, want, die for most people of ignorances?
