dialogue: M: I hear a businessman is building a dog park in our city. W: Really? What for? M: Obviously because there's a law against having dogs in the streets. W: Does it mean that dogs have to stay at home all the time? M: Sounds pretty cruel, right? Maybe a dog park is a good idea. W: Maybe they should just allow people to walk their dogs in the streets. M: But then streets could be a mess. W: Couldn't people clean up after their dogs? M: Would they?

choice: Dogs should be kept at home. Building a dog park is necessary. People would remove the dog waste.
answer: People would remove the dog waste.
