Passage (Questions 96-100)
Urban parks are often described as the lungs of a city. Trees filter dust, lower temperatures during summer and give residents a place to exercise and relax. Studies in several countries link access to green space with lower stress and better mental health. Yet land in cities is expensive, and green areas are often the first to be sacrificed when roads or buildings are planned. Planners are therefore experimenting with rooftop gardens, vertical walls of plants and small 'pocket parks' on unused corners of land. These solutions do not replace large parks, but they can bring a little nature within walking distance of every home.
Why are green areas often the first to be sacrificed in cities?
- ABecause residents dislike parks
- BBecause trees cannot grow in cities
- CBecause land is expensive and roads or buildings are planned instead
- DBecause mental health is not important
Correct answer: C
