A city plans to reduce the number of cars entering its downtown area by charging drivers a fee for entering during peak hours. Since many drivers will not want to pay the fee, the city expects that fewer people will drive downtown during peak hours.
The city's plan assumes thatThe plan depends on the fee actually changing some drivers’ behavior. If everyone continued driving downtown despite the fee, the plan would not reduce the number of cars.
(A) some drivers who currently enter downtown during peak hours will choose not to enter if they must pay a fee
Correct. This is exactly the required assumption. The city expects fewer cars because some drivers will avoid paying the fee and therefore choose not to enter downtown during peak hours.
(B) public transportation in the city is less expensive than driving downtown
Incorrect. Drivers might avoid downtown for many reasons. Public transportation does not need to be cheaper.
(C) most drivers who enter downtown during peak hours are commuting to work
Incorrect. The plan does not depend on why drivers are entering downtown.
(D) the fee will generate enough revenue to cover the city's administrative costs
Incorrect. The goal is to reduce traffic, not necessarily to make money.
(E) traffic congestion downtown is worse during peak hours than at other times
Incorrect. This may explain why the city targets peak hours, but it is not required for the plan to work.
