City leader: If our city adopts the new tourism plan, the amount of money that tourists spend here annually will increase by at least $2 billion, creating as many jobs as a new automobile manufacturing plant would. It would be reasonable for the city to spend the amount of money necessary to convince an automobile manufacturer to build a plant here, but adopting the tourism plan would cost less. The city leader's statements, if true, provide the most support for which one of the following? ['It would be reasonable for the city to adopt the new tourism plan.', 'In general, it is reasonable for the city to spend money to try to convince manufacturing companies to build plants in the city.', 'The city should implement the least expensive job creation measures available.', 'The only way the city can create jobs is by increasing tourism.']
