Urban planner: When a city loses population due to migration, property taxes in that city tend to rise. This is because there are then fewer residents paying to maintain an infrastructure that was designed to support more people. Rising property taxes, in turn, drive more residents away, compounding the problem. Since the city of Stonebridge is starting to lose population, the city government should therefore refrain from raising property taxes. Which of the following, if true, would most weaken the urban planner`s argument?
【选项】Stonebridge at present benefits from grants provided by the national government to help maintain certain parts of its infrastructure.
