City planner Rosa Martinez advocates for mixed-use zoning, arguing that neighborhoods combining residential, commercial, and office spaces create more walkable, sustainable communities. She points to research showing that residents in mixed-use areas drive 30% fewer miles per week than those in single-use suburban developments.
Which additional finding would most strengthen Martinez's argument about sustainability?
Mixed-use neighborhoods have more diverse restaurant options
Property values in mixed-use areas increased by 15% over five years
Carbon emissions per household are 25% lower in mixed-use neighborhoods
Residents in mixed-use areas report higher satisfaction with their neighborhoods
Correct Answer: C
Choice C is the best answer. Martinez argues mixed-use zoning creates "sustainable communities." Lower carbon emissions directly measure environmental sustainability.
- Context clues: The claim emphasizes "sustainable communities."
- Evidence evaluation: Carbon emissions are a direct sustainability metric.
- Verify: 25% lower emissions proves the environmental benefit.
💡 Strategy: Match evidence to the specific aspect of the claim (sustainability = environmental impact).
Choice A is incorrect because restaurant diversity is about convenience, not sustainability. Choice B is incorrect because property values relate to economic factors, not environmental sustainability. Choice D is incorrect because resident satisfaction doesn't measure environmental impact.
