Given the question: Dialogue: M: Air pollution is so bad in this city. I think the government should stop people from driving cars on certain days. W: You have a point. Air pollution is a problem. But not letting people drive on certain days is a bad idea. People have to go to work by car. M: I'm afraid I don't agree with you there. Reducing air pollution is really important. People are so used to driving that they don't think about ways to do things. If we stop them from driving on certain days, maybe they could think of new ways to get around. W: I see your point. But I still think it wouldn't be possible to stop people from driving. Question: What are the speakers talking about? - A way to improve air quality. - A problem with traffic rules. - A suggestion for city planning.
The answer is:
A way to improve air quality.
