Method of Reasoning in Urban Development Discussion

In a discussion regarding urban development, an architect argued that the introduction of mixed-use buildings, which combine residential and commercial spaces, has the potential to revitalize struggling neighborhoods. The architect contended that these developments create vibrant communities by encouraging foot traffic and social interaction, which in turn boosts local businesses. Additionally, the architect suggested that such environments can lessen reliance on cars, promoting sustainability.

However, a city planner countered that while mixed-use development sounds beneficial in theory, evidence shows that they often lead to increased property values, which can displace lower-income residents. This displacement, the planner argued, undermines the goal of creating inclusive communities.

Which of the following best describes the method of reasoning used by the architect in the above discussion?
