Question

Which detail best supports the idea that rooftop gardens have benefits?

1) They are expensive to construct.
2) Gardens help to relieve stress.
3) They reduce energy costs.
4) A tar roof can reach 170 degrees Fahrenheit on a hot day.

Answer 1

The best detail supporting the benefits of rooftop gardens is that they reduce energy costs by providing insulation and thus lowering heating and cooling expenses.

Step-by-step explanation:

The detail that best supports the idea that rooftop gardens have benefits is that they reduce energy costs. Rooftop gardens provide a layer of insulation that can help regulate building temperatures, leading to lower heating and cooling expenses.

They act like a natural thermal barrier, absorbing heat in the summer to keep buildings cooler and providing insulation in the winter to retain warmth. Additionally, having a layer of vegetation on the roof can also aid in collecting rainwater, which can be reused for watering the gardens, further contributing to environmental sustainability and reducing water usage costs.
