Quizplus · Accepted Answer

The question is asking for the largest efficiency gains from deregulation, and the answer is D because airlines, trucking, and railroad industries were heavily regulated prior to deregulation, and after deregulation, they experienced significant improvements in efficiency, lower prices, and increased competition. Natural gas and cable television industries were also deregulated, but their efficiency gains were not as significant as those in the transportation industries. Communications and stock-brokering industries were not heavily regulated to begin with, so their efficiency gains from deregulation were not as significant either.
