Difficulty: MediumCentral Ideas

In the mid-twentieth century, urban planners widely adopted the 'super-block' design, prioritizing vehicular efficiency and high-density housing separated by vast, open lawns. Although intended to provide residents with access to light and clean air, these massive, uniform green spaces often went unused. Urban sociologist Jane Jacobs argued that this failure stemmed from a lack of spatial differentiation and localized purpose. In her view, successful urban spaces require a mixture of uses—such as small shops, residences, and parks in close proximity—to foster regular, organic human activity. Without these diverse daily destinations, the open lawns became desolate zones that failed to integrate into the social fabric of the neighborhood, demonstrating that sheer physical acreage of greenery is insufficient for community engagement.

Which choice best states the main idea of the text?

  1. Large green spaces in urban areas are ineffective at fostering community engagement unless they are integrated with diverse, localized neighborhood uses.Answer
  2. B
    Urban planning models from the mid-twentieth century generally failed to improve the living conditions of city residents.
  3. C
    The 'super-block' design was highly effective at improving vehicular efficiency but failed to provide residents with light and clean air.
  4. D
    Jane Jacobs believed that small shops and parks should be managed by local residents rather than urban planners to ensure organic community activity.

Answer

Large green spaces in urban areas are ineffective at fostering community engagement unless they are integrated with diverse, localized neighborhood uses.
The correct answer accurately states the main idea of the passage. The text explains that the vast green lawns of mid-twentieth-century 'super-block' designs went unused because they lacked spatial differentiation and localized purpose. It cites Jane Jacobs's view that urban spaces must mix multiple uses (like shops, residences, and parks) in close proximity to foster organic activity, concluding that physical greenery alone is insufficient for community engagement.

Step-by-Step Solution

1
Analyze the text structure and content to identify the main topic.
The text discusses mid-twentieth-century urban planning, specifically the failure of large green spaces in 'super-block' designs to foster community engagement.
Understanding the topic is the first step in identifying the central idea.
2
Examine the author's primary argument and Jane Jacobs's perspective.
Jacobs argues that green spaces fail when they lack diverse and localized purposes, and they require a mixture of uses in close proximity to encourage organic activity.
The author uses Jacobs's perspective to support the concluding point that sheer greenery acreage is insufficient for community engagement.
3
Synthesize the main point and evaluate the options.
The option stating that large green spaces are ineffective without integration with diverse, localized uses best captures the overall central idea of the passage.
This matches the text's assertion that successful spaces require mixed uses and that greenery alone does not ensure community integration.
