1)As before, a trolley with tons of explosive is hurtling down a track towards a jerry-built dam... You can divert its path by colliding another trolley into it, but if you do, both will be derailed and go down a hill, and into a yard where a man is sleeping in a hammock. He would be killed. If you don't divert its path, the trolley will hit on the jerry-built dam, at least millions of people will die.
Should you proceed?
2)You can save the five people by pulling a lever, thus diverting the trolley to a different set of tracks where another extraterrestrial is tied up. Do you pull the lever, killing one to save five?
