Exercise 7: Read the passage and answer the questions
Air, water, and soil are necessary to the survival of all living things. Badly polluted air can cause illness, and even death. 
Polluted water kills fish and other marine life. Pollution of the soil reduces the amount of land that is available for 
growing food. The pollution problem is very complicated because much pollution is caused by things that benefit 
people. For example, exhaust from automobiles causes a large percentage of air pollution. But the automobile provides 
transportation for millions of people. Factories discharge much of the material that pollutes the air and water, but 
factories give employment to a large number of people. Thus, to end or greatly reduce pollution immediately, people 
would have to stop using many things that benefit them. Pollution can be gradually reduced in several ways. Scientists 
and engineers can work to find ways to lessen the amount of pollution that such things as automobiles and factories 
cause. Governments can pass and enforce laws that require businesses and individuals to stop, or to cut down on certain 
polluting activities.
