GMATOnTheGo CR (Bold Faced) Test Q #3
Diesel-powered trucks manufactured prior to 1990 contribute significantly to the world’s air pollution. In 1990, however, the government imposed stricter pollution controls on diesel powered trucks, and beginning in 1995, the government imposed a program of inspections for pre-1990 trucks with increasingly rigorous pollution standards. As the older truck engines fail to pass inspection, truck owners are increasingly retiring their trucks in favor of newer, less-polluting trucks. As a result, the amount of pollution these older trucks emit will steadily decrease over the next ten years.
