rapidly. This made it possible to produce great number of cigarettes very quickly, and it reduced the price.

Today cigarette smoking is a widespread habit. About forty -three percent of the men and thirty -one percent of the adult women in the United States smoke cigarettes regularly. It is encouraging to note, however, that millions of people have given up the smoking habit.

Income, education and occupation all play a part in determining a persons smoking habits.

City people smoke more than people living on farms. Well -educated men with high income are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes. On the other hand, if a well -educated man with a high income smokes at all, he is likely to smoke more packs of cigarettes per day. The situation is somewhat different for women. There are slightly more smokers among women with higher family income and higher education than among the lower income and lower education groups. These more highly educated women tend smoke more heavily.

22.Which of the following is true according to the passage?

Passage Three

Life on earth depends on the sun. Day after day we see its light and feel its warmth, but we do not often consider their origin. Yet there are many remarkable things about the sun. One is its distance from the earth. This is about 93 million miles. A journey of this distance, even if it could be made, would take several hundred years even in the fastest rocket.

The sun makes us feel hot, even at a distance of 93 million miles. This is not surprising. The temperature on the sun is about 10,000 degree Fahrenheit. But we receive only a small part of the heat. The total heat of the sun could melt a column of ice two and a quarter miles thick and 93 million miles high in a second.

The brightness of the sun is equally astonishing. As we said earlier, we receive only a very small part of the sun ' s heat. We also receive only a very small part of its light. This is sufficient for

the growth of trees and plants, and for the existence of living creatures on earth. Too much heat and light would destroy the balance of life. The heat and light from the sun come in just the right quantities for life on earth.
