阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

　　The chances are that you made up your mind about smoking a long time agoand decided it's not for you.

　　The chances are equally good that you know a lot of smokers there are, after all about 60 million of them, work with them, play with them, and get along with them very well.

　　And finally it's a pretty safe bet that you're open-minded and interested in all the various issues about smokers and non-smokers or you wouldn't be reading this.

　　And those three things make you really important today.

　　Because they mean that yours is the voice not the smoker's, and not the anti-smoker's that will determine how much of society's efforts should go into building walls that separate us and how much into the search for solutions that bring us together.

　　For one sad result of the emphasis (强调) on building walls is the different uses of millions of dollars from scientific research on the causes and cures of diseases which, when all is said and done, still strike the non-smoker as well as the smoker.

　　One famous health organization to cite (引用) but a single instance, now spends 98 cents of every publicly-contributed dollar on “education”, much of it in anti-smoking propaganda (宣传) and only 2 cents on research.

　　There will always be some who want to build walls, who want to separate people from people and to a certain degree, even these may serve society. The anti-smoking wall-builders have, fairly speaking, helped to know choices more clearly.

　　But our guess, and certainly our hope, is that you are among the far greater number who know that walls can't stand long, and over the long run, we can serve society's interests better by tolerating one another and by working together.

　　Whatever advantage walls may have, they can never move our society toward fundamental solutions. People who work together on common problems, common solutions can.
