Read the following passage regarding urban planning:
In recent decades, urban planners have increasingly championed 'mixed-use development'—the zoning of residential, commercial, and recreational spaces within close proximity—as the panacea for the isolation and environmental degradation associated with urban sprawl. Proponents argue that mixed-use neighborhoods reduce reliance on automobiles, foster vibrant community interactions, and create more efficient local economies. However, empirical studies tracking the implementation of these zones in historically segregated cities reveal a more complex reality. While carbon footprints in these areas have indeed decreased, the revitalization often attracts affluent newcomers, driving up property values and displacing the very lower-income residents the improved infrastructure was purportedly designed to serve. Furthermore, the commercial spaces in these new developments tend to be occupied by corporate chain stores rather than local businesses, leading to a homogenization of the neighborhood's cultural fabric.
Based on the logical structure and argumentative trajectory of the passage, match each prospective next-paragraph extension (Left) with the specific rhetorical function it would serve (Right).
- A proposal for implementing affordable housing mandates and commercial rent caps within new mixed-use zones.Resolves the tension between the intended social benefits of the zoning strategy and its exclusionary economic outcomes.
- An in-depth analysis of the specific commuter transit shifts that caused the recorded decrease in carbon footprints.Elaborates on the sole empirical success of the zoning strategy acknowledged in the author's otherwise critical evaluation.
- A detailed case study illustrating how a historic local market was replaced by a national corporate franchise.Provides concrete evidence to support the author's claim regarding the cultural homogenization of revitalized neighborhoods.
- A theoretical critique questioning the premise that spatial proximity inherently fosters vibrant community interactions.Directly challenges a specific claim made by proponents that is undermined by the demographic shifts described by the author.
