In mid-twentieth-century urban planning, the dominant paradigm advocated by Robert Moses favored large-scale slum clearance and highway construction, assuming these interventions would revitalize declining cities. However, sociologist Jane Jacobs challenged this approach, arguing that vibrant, dense neighborhoods with mixed-use zoning naturally foster safety and economic stability. Jacobs's bottom-up theory posited that diverse street life encourages informal surveillance, which keeps communities secure. Today, many urban planners have abandoned Moses's top-down strategies in favor of Jacobs's community-centered model, demonstrating a paradigm shift in how city design is understood to affect social cohesion.
Which choice best describes the overall structure of the text?
- AIt advocates for the implementation of mixed-use zoning laws by analyzing the failure of specific mid-twentieth-century slum clearance projects.
- BIt proposes a solution to a contemporary urban design problem, reviews historical objections to that solution, and concludes by validating the original proposal with modern data.
- It outlines an established urban planning methodology, introduces an alternative perspective that disputes that methodology's assumptions, details the mechanism of the alternative model, and notes the current impact of this theoretical shift.Answer
- DIt traces the chronological evolution of Robert Moses's planning career, details his collaborations with Jane Jacobs, and explains how their joint work stabilized declining cities.
