The Petroleum Act, which goes into effect next May, will be good for gas station owners because it will eliminate the import duties levied on imported crude oil, which is refined to produce most of the gasoline in this country. The elimination of the duties will result in a savings of nearly 15 percent that can be passed along to the customers, thereby promoting higher sales and profits.
Which of the following, if true, would most weaken the argument that the Petroleum Act will be good for gas station owners?The argument says the Act will help gas station owners because eliminating import duties on crude oil will lower gasoline costs, and those savings can be passed on to customers, leading to higher sales and profits.
The key assumption is that the Act does not impose some other cost that would outweigh that benefit.
If the Act adds an even bigger new tax on gasoline sales, the argument falls apart.(A) Per capita consumption of gasoline has steadily increased over the last two years, and is expected to increase this year even without the Petroleum Act.
This does not weaken the argument much. Rising gasoline consumption does not show that the Act will not also help gas station owners.
(B) Many gas station owners will not pass along to consumers all of the savings from the elimination of import duties.
This weakens the argument somewhat, because the argument says higher sales will come from passing savings on to customers. But owners could still benefit by keeping more of the savings as profit.
(C) Duties levied on imported natural gas will not be eliminated by the Petroleum Act.
This is irrelevant. The argument is about gasoline made from crude oil, not natural gas.
(D) Consumption of gasoline produced from domestic crude oil is expected to fall as a result of the Petroleum Act.
This does not clearly weaken the claim about gas station owners. Gas station owners sell gasoline; the source of the crude oil does not by itself show that owners will be worse off.
(E) The Petroleum Act includes a new 20 percent tax on gasoline sales
This weakens the argument the most. The argument relies on a savings of nearly 15 percent from eliminating import duties. A new 20 percent tax on gasoline sales would more than offset that savings and could reduce profits instead of increasing them.
Answer: (E)
