Which of the following, if true, casts the most serious doubt on the conclusion drawn above?

The real-estate tax rate in Middletown is higher than it is in the suburbs.
Last year voters in the suburban communities defeated by a narrow margin a bill designed to increase subsidies for public bus routes.
Many suburban shops can attract enough employees to remain in business only because subsidized public transportation from Middletown is available.
Public buses operated with less than a 35 percent occupancy rate produce more pollution per passenger mile than would the operation of private automobiles for each passenger.
Most voters in Middletown’s suburban communities are unwilling to continue subsidies for public buses next year if rider ship on those buses drops below current levels.
