Fares on the city-run public buses in Greenville are subsidized by city tax revenues, but among the beneficiaries of the low fares are many people who commute from outside the city to jobs in Greenville. Some city councilors argue that city taxes should be used primarily to benefit the people who pay them, and therefore that bus fares should be raised enough to cover the cost of the service.
Each of the following, if true, would weaken the argument advanced by the city councillors EXCEPT:
A．Many businesses whose presence in the city is beneficial to the city’s taxpayers would relocate outside the city if public-transit fares were more expensive.
B．By providing commuters with economic incentives to drive to work, higher transit fares would worsen air pollution in Greenville and increase the cost of maintaining the city’s streets.
C．Increasing transit fares would disadvantage those residents of the city whose low incomes make them exempt from city taxes, and all city councillors agree that these residents should be able to take advantage of city-run services.
D．Voters in the city, many of whom benefit from the low transit fares, are ply opposed to increasing local taxes.
E．(E) People who work in Greenville and earn wages above the nationally mandated minimum all pay the city wage tax of 5 percent.
