Urban heat islands (UHIs) are areas where city infrastructure absorbs and retains heat, making them warmer than surrounding rural areas. To combat this, urban planners have widely introduced vegetative roofs, which utilize evapotranspiration to cool buildings and lower ambient air temperatures. However, sociologist Dr. Clara Vance notes that vegetated roof initiatives are disproportionately implemented on commercial high-rises and luxury residential developments in high-income neighborhoods. Because lower-income areas typically have higher baseline temperatures and fewer green spaces, she argues that unless cities alter their current distribution policies for vegetated infrastructure, these sustainability initiatives will likely Which choice most logically completes the text?

  1. fail to mitigate urban heat island effects in the communities that experience the most severe baseline temperatures.Answer
  2. B
    result in an overall decrease in green infrastructure in high-income neighborhoods due to spatial constraints.
  3. C
    encourage urban planners to prioritize rural reforestation projects rather than urban sustainability initiatives.
  4. D
    prove that vegetated roofs are structurally incompatible with older residential buildings in low-income areas.

Answer

The correct option is the one stating that the initiatives will fail to mitigate urban heat island effects in the communities that experience the most severe baseline temperatures.
The correct choice logically flows from the contrast established in the text. Vegetated roofs are effective at cooling buildings and lower-income areas are hotter and less green, but current policies favor installing these roofs in wealthier areas. Thus, unless distribution policies change, the areas experiencing the highest baseline temperatures will continue to miss out on the cooling benefits of this green infrastructure.

Step-by-Step Solution

1
Identify the premises regarding urban heat islands and vegetated roofs.
Vegetated roofs cool urban areas, but they are currently concentrated in wealthier neighborhoods.
Establishing the baseline facts of the passage is necessary to trace the logical progression.
2
Analyze the conditions of low-income neighborhoods described by Vance.
Low-income areas have higher baseline temperatures and fewer green spaces.
This establishes where the cooling intervention is most critically needed.
3
Synthesize the contrast between current distribution and neighborhood needs to draw a conclusion.
If policies do not change, the cooling benefits will continue to bypass the hottest and most vulnerable areas.
Connecting the lack of policy change with the existing disparity leads directly to the logical completion of Vance's argument.
