Benson: In order to maintain the quality of life in our city, we need to restrict growth. That is why I support the new zoning regulations. Willett: I had heard such arguments ten years ago, and again five years ago. Each time the city council was justified in deciding not to restrict growth. Since there is nothing new in this idea of restricting growth, I oppose the regulations. Which one of the following most accurately describes a way in which Willett's reasoning is questionable? ['It fails to take into account the variety of factors that contribute to the quality of life in a city.', "It is based on attacking Benson personally rather than responding to Benson's reasoning.", 'It overlooks the possibility that the city council of ten years ago was poorly qualified to decide on zoning regulations.', 'It ignores the possibility that new reasons for restricting growth have arisen in the past five years.']
