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?
The 15-minute neighborhood concept offers potential benefits but faces implementation challenges
Walking is healthier than driving in urban areas
Critics oppose all urban planning innovations
Housing costs are rising in all major cities
Correct Answer: A
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 concept.
- Evidence: The text mentions both "proponents argue" and "critics caution."
- Reasoning: The balanced presentation indicates the main idea encompasses both perspectives.
- Conclusion: The text discusses both benefits and implementation concerns.
Choice B is incorrect because the text is about urban planning concept, not health benefits. Choice C is incorrect because critics have specific concerns, not general opposition. Choice D is incorrect because housing costs are mentioned only as one specific concern.
