The crisis also led to a sharp increase in unemployment and a fall in housing prices, causing a global economic recession.
案例三：物体跌落

This fragment dropped from the sky and landed in a farmer's field, creating a small crater. The event attracted scientists and media attention, as meteorite falls are relatively rare and provide valuable information about the early solar system.
