Aliens have invaded earth and captured a number of scientists and you happen to be one of them. The aliens take you to their planet and discover that you are not as intelligent as they might have thought. To try and prove this wrong, their leading scientists decides that you'll be left with the option to decide your own fate. You are all lined up in a queue stepping on some boards on top of a deep gorge with volcanic magma at the bottom. Each board has a light that is either green or blue when lit. You can see the lights of all people ahead of you but you cant see your own light. You are then told to guess the color of your light. If you are wrong, your board breaks and you fall into the magma and die painfully. You are given sometime to discuss with your friends how to choose who dies. What is the maximum number of people that you can save? -- Solomon Kariri, Software Developer, Cell: +254736 729 450 Skype: solomonkariri
