Some scientists【C8】______ pushing asteroids off course with nuclear weapons. But the cost wouldn’t be cheap. Is it【C9】______ it? Two things experts consider when judging any【C10】______ are how likely the event is and how bad the【C11】______ if the event occurs. Experts think an asteroid【C12】______ enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty【C13】______ — but if one did fall, it would be the【C14】______ of the world. "【C15】______ we don’t take care of these big asteroids, they’ll take care of us.
