The key answer of exercise 3

A: I read somewhere that almost half the world lives on less than £2.50 a day. It’s Rea depressing, isn’t it?

B: Oh, it’s just horrible! I hate to think about it. There is some hope, though. According to a recent report, the African economy has grown by 5%.

A: There are reasons to be optimistic, then. But I'd still like to see governments doing more to tackle the problem.

B: It's not too late to make a difference. Why don’t we join a charity organisation to help raise money for poor people?

A: That's a great idea.
