The Simulator

Dozens of years ago some phsycho-ball set off a nuclear chain reaction between nuclear power plants, causing an explosion killing and destroying most of Northern U.S.A. More than half of southern U.S.A was saved. My grandparents, and most of the people in the south went into bunkers for the past seventy-something years. Then scientist figured out it was safe to come out as long as people stayed in the most southern sectors. The few countries that had been on good terms with us when it happened used a process called Annihilating RZ to lower the levels of radiation. Whatever it did, it cleared up the radiation dozens of years faster than it originally would. Coming up is the annual Semi-Simulators. To keep the people safe and from stopping another idiot from destroying the rest of our home. Every year all fifteen-year-olds are tested in every category in a simulative game. If your to be one of the five to win? Your sent to be trained for The Simulator.
