(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.This option merely highlights a procedural requirement (public hearings) but does not suggest that the toll increase itself will fail to generate the needed funds.
(B) Whenever bridge tolls are increased, the authority must pay a private contractor to adjust the automated toll-collecting machines.This option mentions an additional cost but does not imply that the toll increase would significantly fail to generate sufficient revenue for the improvements.
(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.This option suggests a temporary delay in the collection of increased tolls but does not indicate a long-term impact on revenue generation.
(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.This option is the most relevant. It suggests that increasing tolls could lead to a significant number of drivers avoiding the toll bridges altogether, which would reduce the anticipated revenue from the toll increase, thus undermining the plan's effectiveness.
(E) The chairman of the authority is a member of the Tristate Automobile Club that has registered strong opposition to the proposed toll increase.This option introduces a potential conflict of interest or opposition but does not directly address whether the toll increase would generate the expected funds.
