The town of Utopia has three equal-size groups of people: (i) type A people consistently prefer larger public parks to smaller; type B people prefer small public parks to large public parks, and they prefer large size to medium size parks; type C people most prefer medium size to small size public parks, which they in turn prefer by a modest amount to large levels.

a. Draw on a graph the preferences of the three groups of individuals. Which types of people have single-peaked preferences? Which have multi-peaked preferences?

b. Will round-robin majority voting generate consistent outcomes in this case? Why or why not???
