PART VII: (2.0 pts) Read the following passage and circle the answers A, B, C or D which is most accurate according to the information given in the passage.
In order to help solve the problem of pollution, people have to be aware of its causes, some of which are quite obvious in everyday life. In many cities people are forced to breathe in polluted air, commonly known as smog, which is a mixture of gases sent out by car exhausts and factory chimneys. What can be done to reduce air pollution is to remove factories from cities and use lead-free petrol in cars.
The pollution of rivers, lakes and seas leads to the death of the creatures that live in them. Factories are largely responsible for the present situation, which is expected to worsen if governments do not make them to obey the law against pollution and punish industries which pollute water.
Finally, all over the world, especially in cities, we see huge amounts of rubbish in the streets, which we are responsible for. The rubbish collection system often does not work properly and people themselves add to the problem by dropping litter in the streets. There is so much we could do to help solve the problem. The point is how willing are we to do something about it?
