Speaker 1 I don’t think the council has the right to put computer chips in bins. I mean, what about privacy? It’s terrible. It’s like living in a police state! This is what happens when councils have too much power! Speaker 2 Maybe putting computer chips in bins is a bit too much, but we have to do something. People just aren’t recycling enough – so we need to educate them. The chips are just getting information, aren’t they? If it helps people to be better citizens, then I think it’s OK. Speaker 3 I reckon this is just the first step. Next, they’ll put computer chips in your home to see if you turn the lights out – and computer chips in your car to see if you’re driving too fast. It’s frightening! I hate the idea! Speaker 4 I think it’s a great idea. We all need to recycle – but some people refuse to do it – or they’re too lazy. And who pays for their mistakes? Our children. And our grandchildren. This is important – we’ve only got one planet! Speaker 5 I don’t like the idea of computer chips in bins. How much can they find out about your rubbish? Can they see it? It’s like somebody looking in your bin, isn’t it? Nobody would like that. I’d feel embarrassed. 1 D 2 C 3 F 4 A 5 B
