The national infrastructure for airport runways and air traffic control requires immediate expansion to accommodate the increase in private, smaller planes. To help fund this expansion, the Federal Aviation Authority (FAA) has proposed a fee for all air travelers. However, this fee would be unfair, as it would impose costs on all travelers to benefit only the few who utilize the new private planes.

Which of the following, if true, would cast the most doubt on the claim that the proposed fee would be unfair?

(A) The existing national airport infrastructure benefits all air travelers.
(B) The fee, if imposed, will have a negligible impact on the overall volume of air travel.
(C) The expansion would reduce the number of delayed flights resulting from small private planes congesting runways.
(D) Travelers who use small private planes are almost uniformly wealthy or traveling on business.
(E) A substantial fee would need to be imposed in order to pay for the expansion costs.
