Read the following passage and mark the letter A, B, C or D to indicate the correct

answer to each of the question

Everyone wants to reduce pollution. But the pollution problem is as complicated as it's

serious. It's complicated because much pollution is caused by things that benefit people.

For example, exhaust from automobiles causes a large percentage of all air pollution. But

the automobile provides transportation for millions of people. Factories discharge much

of the material that pollutes air and water, but factories give employment to a large

number of people. Too much fertilizer or pesticide can ruin soil, but fertilizers and

pesticide are important aids to the growing crops. Thus, to end or reduce pollution

immediately, people would have to stop using many things that benefit them. Most

people do not want to do that, of course. But pollution can be gradually reduced in

several

ways.
