Question 16:

a.        When summer comes, city temperatures rise higher than countryside areas because dark streets absorb sunlight while green forests stay cool and give fresh air.

b.        Although this problem seems difficult, we can help if we plant more trees and paint roofs white because light colors reflect the sun's heat.

c.        Since climate change grows stronger, cities must act quickly before temperatures become dangerous, or people will get sick when heat waves come every summer.

d.        Cities become very hot because buildings and roads keep heat inside, and trees cannot grow when there is too much concrete everywhere around us.

e.        People feel tired when cities get too hot, so they use more air conditioning, but this makes the problem worse because machines produce heat.
