According to the Tristate Transportation Authority, making certain improvements to the main commuter rail line would increase ridership dramatically.The authority plans to finance these improvements over the course of five years by raising automobile tolls on the two highway bridges along the route the rail line serves.Although the proposed improvements are indeed needed, the authority's plan for securing the necessary funds should be rejected because it would unfairly force drivers to absorb the entire cost of something from which they receive no benefit.

Which of the following, if true, would cast the most doubt on the effectiveness of the authority's plan to finance the proposed improvements by increasing bridge tolls?

(A) Before the authority increases tolls on any of the area bridges, it is required by law to hold public hearings at which objections to the proposed increase can be raised.

(B) Whenever bridge tolls are increased, the authority must pay a private contractor to adjust the automated toll-collecting machines.

(C) Between the time a proposed toll increase is announced and the time the increase is actually put into effect, many commuters buy more tokens than usual to postpone the effects of the increase.

(D) When tolls were last increased on the two bridges in question, almost 20 percent of the regular commuter traffic switched to a slightly longer alternative route that has since been improved.

(E) The chairman of the authority is a member of the Tristate Automobile Club that has registered strong opposition to the proposed toll increase.

But only 20% drivers stop,if the doll increases more than 20%, enough money would be generated for the project,also!
I think the answer is B, because the authority must pay a private contractor ,maybe there is not enough money left for the project

The toll increase is designed to get EXTRA cash in order to fund the project.  If drivers stop using the toll road, there would be enough money to cover the origal goal of the toll, let alone to fund the new project.

If as you said, raise the toll by 20%, there would be any EXTRA money collected for the new project.

For B, whatever the cost would be covered by the increase in toll.

D) is the answer since if drivers stop using the toll road, not enough money would be generated for the project.
