printf("\n a: Since the speed is reduced in half, we must reduce the kW rating in half. Consequently, the 25kW, 900 rpm dynamo has the same size. ");
printf("\n\n b: Since we have cut the speed in half but maintained the same kW rating, the dynamo has twice the size as the original.");
printf("\n\n c: Half the size. ");
printf("\n\n d: Same size. ");
