题目材料：
A plant-based automobile fuel has just become available in Ternland. A car can be driven as far on a gallon of the new plant-based fuel as a car can be driven on a gallon of gasoline, but a gallon of the plant-based fuel both costs less and results in less pollution. Therefore, drivers in Ternland who switch to it will reduce the amount they spend on fuel in a year while causing less environmental damage.
Which of the following is an assumption on which the argument relies?
-
A.There is no expense associated with operating an automobile that is higher when the automobile uses the plant-based fuel than when it uses gasoline.
-
B.Automobiles that have been operated using the plant-based fuel can no longer be operated using regular gasoline.
-
C.The environmental damage attributable to automobiles is due almost entirely to the production and combustion of fuel automobiles use.
-
D.The advantages of the plant-based fuel over gasoline will not lead those who switch to the plant-based fuel to do more driving.
-
E.Most drivers in Ternland will switch from gasoline to the plant-based fuel.
