A: It’s a pity, but I think you’re right. We already have posters all over campus, and so the message might get lost. We need to make a stronger impact. C: In my eyes, we should have a school debate on how best to solve the problem of world hunger. B: The advantages are that it would help get people involved and interested. A: But I think the problem with a debate is that it doesn’t really hit home. People will learn more about world hunger, that’s true. I have a feeling that very few people will actually be motivated to do anything about world hunger through a debate. B: My view is that we should have a World Food Day Sunday Dinner. Sample Dialogue C: What is that? B: Well, everyone buys tickets to eat a dinner, and the price of the tickets is the same. But when they buy the tickets they have to draw their tickets at random. Some people get tickets to eat like a poor person — just a small bowl of rice. Others get tickets to eat like an average person — noodles with meat, perhaps. Finally, others get tickets to eat like a king — roast duck and all sorts of sweets. C: Without doubt, that is the craziest thing I’ve ever heard. B: No, no. I don’t think it’s crazy at all. A: What’s the purpose of such a meal? B: In real life, how well a person eats is really just a matter of luck. If you are born in a wealthy country, you probably eat well and might even be fat! But if you are born in a poor country, you might just starve! A: I believe that you might be onto something. But who’s going to cook the food?
