英文正文
Vincent: If you don't want the powder to cost more, we can't add anything. We'll just have to sell it the way it is now, and put a warning on. Then, if someone uses dirty water, they shoulder the responsibility, not us.
Grace: I'm sorry, but I have to disagree. There are three very good reasons why it would be the wrong thing to do.
Vincent: You seem very sure of what you are saying. Can you back it up?
Grace: As I see it, first of all most people there can't read, so a warning won't help them at all. Second, even if their governments say a warning is enough, other groups won't. They'll call out the media hounds, and many people will be very, very angry with us. Sales will go down everywhere.
Sam: Hm. You said that there are three good reasons, Grace. Is there another reason you want to add?
Grace: Yes, there is. Third, and most important, it just wouldn't be right if we knew even one person wouldn't listen to the warning, and a child was hurt because of it.
Sam: Hm. You can't argue against that. How could we live with ourselves if we let that happen? And just because we wanted more money.
Vincent: It wouldn't just be because of the money. Those people aren't healthy, and our powder is better than mother's milk. Some people might get sick, but isn't it more important that we help so many others?
