In order to increase revenues, an airport plans to change the parking fees it charges at its hourly parking lots. Rather than charging $2.00 for the first two-hour period, or part thereof, and $1.00 for each hour thereafter, the airport will charge $ 4.00 for the first four-hour period, or part thereof, and $1.00 for each hour thereafter.
Which of the following is a consideration that, if true, suggests that the plan will be successful in increasing revenues

A．Very few people who park their cars at the hourly parking lot at the airport leave their cars for more than two hours at a time.

B．Over the past several years, the cost to the airport of operating its hourly parking facilities has been greater than the revenues it has received from them.

C．People who leave their cars at the airport while on a trip generally park their cars in lots that charge by the day rather than by the hour.

D．A significant portion of the money spent to operate the airport parking lot is spent to maintain the facilities rather than to pay the salaries of the personnel who collect the parking fees.

E．(E) The hourly parking lots at the airport have recently been expanded and are therefore rarely filled to capacity.
