The mayor of Island City has proposed that the toll on all bridges leading into the city be doubled after the first of next year. The mayor claims that the increased fee will cause large numbers of motorists to choose alternate forms of transportation into the city. According to the mayor, this shift will benefit the environment because of lower automobile emissions, will decrease traffic congestion in the city center, and will increase revenues for the city's light rail system.
Each of the following, if true, would weaken the argument put forth by the mayor EXCEPT:
(A) In order to avoid the new toll, many motorists will begin using car ferries to the city. The ferries are known to produce large amounts of toxic emissions.
(B) In a recent survey, 98% of automobile commuters to the city claim that the increase in tolls will not cause them to stop driving to the city every day.
(C) In addition to the increased tolls, the city council intends to lower the charge for the city's light rail system.
(D) Island City has planned a large number of street renovation projects to begin in the city center at the same time as the increased bridge tolls.
(E) The increased toll will result in an increase of approximately $1,500 per year for each motorist that drives into the city five times a week.
