The following text is about architecture.
Green roofs—rooftops covered with vegetation—are becoming common in cities worldwide. These living surfaces absorb rainwater, reducing strain on drainage systems during storms. They also provide insulation, lowering heating and cooling costs for buildings beneath them. Beyond these practical benefits, green roofs create habitat for birds and insects and provide pleasant green spaces in otherwise gray urban landscapes.
Which choice best summarizes the text?
Green roofs offer multiple environmental and practical benefits in urban settings
Green roofs are too expensive for most buildings
Birds prefer green roofs to natural habitats
All new buildings are required to have green roofs
Correct Answer: A
Choice A is the correct answer. The text lists multiple benefits: rainwater management, insulation, habitat creation, and aesthetic improvement.
- Evidence: Multiple specific benefits listed.
- Reasoning: Practical (water, energy) and environmental (habitat, aesthetics) advantages.
- Conclusion: Green roofs provide diverse urban benefits.
Choice B is incorrect because cost isn't discussed. Choice C is incorrect because preference comparison isn't made. Choice D is incorrect because no mandate is mentioned.
