Through Topeka airport, consumer travel by plane is just voluminous

­Through Topeka airport, consumer travel by plane is just voluminous enough for the commercial airlines to make modest profits. The size of the city's population is stable and is not expected to increase much. Yet there are investors ready to double the number of flights to and from the airport within ten years, and they are predicting solid profits both for themselves and for the established airlines.

Which of the following about the city of Topeka, if true, most helps to provide a justification for the investors' prediction?

A. Over the next ten years, people in their middle-aged years, the prime traveling age, will be a rapidly growing proportion of the city's population.

B. As distinct from the existing flights, most of the flights being planned would be run at "very early" morning times, in hopes of stimulating interest in those schedules.

C. Spending on train and bus travel to and from Topeka has been increasing modestly each year for the past ten years.

D. The average number of seats per flight is lower among existing routes than it is among routes still in the planning stages.

E. The sale of snacks and drinks in-flight accounts for a steadily growing share of most airlines' profits.
