C
A provincial government plans to raise the gasoline tax to give people an incentive to drive less, reducing traffic congestion in the long term. However, skeptics point out that most people in the province live in areas where cars are the only viable transportation to jobs and stores and ttherefore cannot greatly change their driving habits in response to higher gasoline prices. In light of the skeptics' objection, which of the following, if true, would most logically support the prediction that the government's plan will achieve its goal of reducing traffic congestion?
A: The tax will encourage many residents to switch to more fuel-efficient cars, reducing air pollution and other problems.
B: Most residents who cannot greatly change their driving habits could compensate for high gasoline prices by reducing other expenses.
C: The revenue from the tax will be used to make public transportation a viable means of transportation to jobs and stores for far more people.
D: Traffic congestion is an especially serious problem for people for whom cars are the only viable means of transportation.
