answer: #Person1# and #Person2# complain about heavy traffic and pollution and talk about possible solutions. Finally, they think working at home may help.
documents: #Person1#: Too much traffic today. I was late for work again!
  #Person2#: I know what you mean. I was stuck for 20 minutes!
  #Person1#: Seems to be getting worse every day.
  #Person2#: More People are living in the city, more cars on the road. Doesn't seem like the problem will get any easier in the future.
  #Person1#: No good for the environment either. Pollution is terrible. Soon we won't be able to breathe the air.
  #Person2#: Don't be so gloomy. Everyone's talking about clean energy nowadays.
  #Person1#: True, that would be great. But it doesn't solve the traffic problem.
  #Person2#: That's right. I think if more people took the bus, then there would be fewer cars on the road.
  #Person1#: The bus? You can't fit anymore people on the bus. They are always crowded!
  #Person2#: Well, then we need more buses.
  #Person1#: More buses on the road means more traffic, which means more pollution.
  #Person2#: Right again. Well, how about if we work at home? Use the Internet, then we'd never have to travel.
  #Person1#: Yeah, and you would be on time for work everyday.
  #Person2#: That'd make the boss happy.
