15-Minute Neighborhoods
Central Ideas & Details • Set 1
PASSAGE
The following text is from an article about urban planning.
Cities around the world are experimenting with "15-minute neighborhoods"—urban areas where residents can access all essential services within a 15-minute walk or bike ride. Proponents argue that such neighborhoods reduce car dependency, strengthen community bonds, and improve quality of life. However, critics caution that implementing this concept in existing cities requires significant infrastructure changes and may inadvertently increase housing costs in desirable areas.
Which choice best states the main idea of the text?
Detailed Explanation
Choice A is the correct answer. The passage presents both the benefits (reduced car dependency, stronger community bonds) and the challenges (infrastructure changes, housing costs) of the 15-minute neighborhood concept.
Key Evidence:
- "Proponents argue" → benefits listed
- "However, critics caution" → challenges listed
- Balanced presentation = main idea encompasses both
Why other choices are wrong:
- B: Health isn't mentioned in the passage—too narrow focus.
- C: Misrepresents critics—they have specific concerns, not general opposition.
- D: Too narrow—housing costs are just ONE concern mentioned.
💡 SAT Strategy Tip:
When a passage presents "proponents say X, but critics say Y," the main idea usually acknowledges BOTH perspectives.
