【正确答案】 C

【答案解析】[听力原文] 18-20
A tricky question in investing is how much of a role ethics should play in your stock selections.
Should you invest in companies that manufacture weapons? What about nuclear power? Alcohol? Gambling? Tobacco? Those are the "Big Five" in terms of ethical decisions. They tend to provoke the strongest emotions, and come up most often in discussions of ethical investing.
But the list could go on and on. Should you invest in companies that have been fined for polluting the environment? Companies that have been sued for racial discrimination? Companies that don't have women in key positions? Companies that do animal testing? Companies that sponsor sexually explicit TV shows or art exhibitions?
The world being what it is, too fine an ethical filter could quickly screen out almost every large company and many small ones.
I tend to be tolerant of most vices in life, and also in investing. I am currently seeking out defense stocks. I'm eyeing at least one nuclear-power stock, and I am favorably disposed toward gambling stocks. There's no liquor stock I want to own, but if the numbers looked attractive, I'd buy one.
