问题     Today, cigarette smoking is a widespread habit. About 43 percent of the adult men and 31 percent of the adult women in the US smoke cigarettes regularly. It is encouraging to note, however, that millions of people have given up the smoking habit. 75 percent of the male population and 46 percent of the female population have smoked cigarettes at some time during their lives, but 26 percent of these men and 11 percent of the women have stopped smoking. The number of persons who have given up smoking is increasing.
    It is a fact that men as a group smoke more than women. Among both men and women the age group with the highest proportion of smokers is the age group 24-44.
    Income, education, and occupation all play a part in determining a person’s smoking habits. City people smoke more than people living on farms. Well-educated men with high incomes 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 higher 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 incomes and higher education than among the lower income and lower educational groups. These more highly educated women tend to smoke more heavily.
    Among teenagers the picture is similar. There are fewer teenaged smokers from upper-income, well-educated families, and fewer from families living in farm areas. High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school. Children are most likely to start smoking if one or both of their parents smoke.
What determines a person’s smoking habits?
选项 A、Age, income and education
B、Age, sex and income.
C、Occupation, income and sex
D、Profession, income and education
答案D
解析 题干关键词determines a person’s smoking habits与原文第三段首句重现，可据此定位。原文中的income，education与选项A和D重现，但occupation只与选项D中的profession对应。故答案为D。
