单项选择题

To provide extra revenue for improving city bus service, the mayor of Greenville proposed a fare increase. The director of the bus service, however, pointed out that the previous bus fare increase had resulted in so many regular riders abandoning the bus system altogether that revenues from bus service had decreased. Another fare increase, the director argued, would only lead to another revenue drop.
The director’s argument depends on which of the following assumptions

A．The previous fare increase was the same amount as the proposed fare increase.

B．Fare increases do not necessarily lead to lower revenues from city bus service.

C．A decrease in fares would result in increased ridership and increased revenues from bus service.

D．The fare increase would make Greenville’s bus service much more expensive than bus services in other comparable cities.

E．(E) Some of the people currently using the bus have the option of not traveling by bus.
