单选题根据下面资料，回答题
Richard:
In my opinion, smoking is only an amusement, like playing cards, reading, etc. Many years ago, when an adult handed me a cigarette and lit it for me, I felt grown up. When I am with friends and have nothing to say, we smoke, consequently we no longer feel embarrassed. Some-times, I light a cigarette, suffering and nervousness vanishing with the smoke, I can´t help saying inwardly: Hello, cigarette, my old friend, I´ m coming to meet you again.
Stanton:
Many people believe smokers have the right to smoke. But they also believe that others shouldn´t have to pay a price. The risk of tobacco smoke is greater than the risk of radon gas is to non-smokers. We´re talking maybe 40 percent greater. And if you´re talking about all the carcino-genic air pollutants that EPA regulates, it´s 100 times greater.
Davis:
According to our investigation, tobacco smoke in the home and workplace could be killing 46,000 non-smokers each year in the United States. That´s 3,000 lung cancer deaths,11,000 from other cancers and 32,000 heart disease deaths. That would make passive smoking the leading preventable cause of death in the United States after alcohol and smoking itself. Smoking kills 390,000 while alcohol 120,000.
James:
Passive smoking has become the principal battleground for the tobacco industry and its oppo-nents in the 1980s. It is no longer merely a health issue, but political and environmental. Cigarette pollution is fouling the air. According to the Environmental Protection Agency´s indoor air program´s result, we know that the indoor environment is far more polluted than the outdoor envi-ronment. We´ve seen that again and again wherever we´ve looked all over the United States.
Winston:
Sir, another fact about smoking is that cigarettes give people a good deal of pleasure. There is considerable evidence, surprisingly little publicized, showing that smoking produces certain benefi-cial effects in human beings. Smoking counteracts some decrease in efficiency, and smokers im-prove their performance in complex situations while smoking. There is also evidence showing that nicotine can produce a tranquilizing effect during high emotional and shock situations, while on the other hand stimulating concentration in tedious situations.
