Question
Write down the conversation between Bill and his friend Andy.
Answer
- Bill: I'm worried about pollution.
- Andy: What exactly do you mean?
- Bill: What I'm trying to say is that each of us should blame ourselves for the tons of waste we produce every day.
- Andy: That's right, and some kinds of waste will take years to disappear. If I've understood correctly, using glass bottles could be a good alternative because it's possible to recycle them.
- Bill: And we should also consider alternative energy sources.
- Andy: Can you clarify that?
- Bill: In other words, renewable energy comes from natural resources like the sun or the wind, which are always available and inexhaustible.
