The document describes a scenario where 13 people are trapped in a bunker after a viral apocalypse wipes out the rest of the planet's population. The bunker only has enough supplies to sustain 4 people for the 2 years it will take for the virus to dissipate. The group must decide which 4 people to sacrifice in order to maximize the chances of repopulating the earth. They choose to keep a scientist, doctor, pregnant woman, and engineering professor based on their specialized skills. The others, including a priest, drug addicts, disabled person, and lazy dependent are sacrificed as they are deemed less able to contribute to the group's survival.
