2) Rooftop gardens, though expensive, have many benefits.
3) Rooftop gardens are cheap to build and good for the environment.
4) The city hall garden is not open to the public.

Answer 1

The text highlights the importance and benefits of incorporating gardens and green spaces into urban areas to improve quality of life and create sustainable city landscapes.

Option '3' is the correct.

Step-by-step explanation:

The main idea of the article seems to focus on the concept of integrating nature into urban spaces to enhance the quality of life through the beauty of gardens.

Rooftop gardens and parks are not just aesthetic elements but also serve environmental purposes and represent a vision for more sustainable and livable cities.

While the text provides various examples, such as Gardens by the Bay in Singapore and One Central Park in Sydney, it emphasizes the broader concept of urban greenery rather than the cost of individual garden projects or their public accessibility.
