A Suspension Bridge
Before airplanes were invented, a suspension bridge was being planned to span a violent river. There was no way a boat could carry the suspension cables across the violent water, and the bridge could not be built until the cables were in place. The builders decided to hold a contest to solve the problem. The contest was won by a young boy. Shortly thereafter the cables spanned the water.
