11. Read the passage and answer the multiple-choice questions.
In Croydon City many years ago, a large number of paintings were damaged by “bad” air, and many people in the city died and thousands of others became ill from fumes in the air in only one year. Aữ pollution, or dirty aứ, is caused by many things. Great clouds of smoke come from factory chimneys. Cars send smoke and fumes into the aữ. Burning waste fills the aữ with bits of dirt. Even burning leaves add smoke to the air. Smoke of all kinds is bad to breathe and can do great harm to the body.
We will have a problem with aữ pollution. However, things got better later in the city because the city council made a decision to limit the amount of fumes cars can exhaust into the air. The decision also set limits on pollution from power plants and íactories.
Although scientists are not able to stop air pollution, they are successíul in finding ways to make cars and factories bum fuel more cleanly. People are also more careful than they once were. For example, they try not to bum fallen leaves in the autumn. We still have a long way to go. But if we all work together, we can solve the problem.
