Due to a sharp rise in the price of gasoline, commuters who drive to work in the center of the city are facing a large increase in transportation expenses that will limit the funds they have available to spend in other areas. In order to forestall a slowdown in the local economy, the city council has decided that fares on all forms of public transportation will be suspended for the next three months. Clearly, if commuters can get to work more cheaply, they will have more money left over to spend in other sectors of the economy, and the city’s finances on the whole will not be negatively affected by higher gasoline prices.
Which of the following is an assumption underlying the plan to avoid a slowdown in the city’s economy?
• Three months is a sufficient period of time to allow gasoline prices to stabilize.
• Commuters who usually drive to work will begin taking public transportation if it is free.
• Other factors in the local economy are affecting the price of gasoline.
• The cost of parking in the city will remain relatively stable.
• People who work in the city are more likely to drive than to take public transportation.
