Yes, I think we should keep old buildings in cities. They show our history and culture, and they make the city look more interesting. Also, tourists like to visit these places, so it helps the city make money.

No, I think sometimes it's better to build new things. Some old buildings are not safe or useful anymore, and cities need more space for new houses or offices. Also, fixing old buildings can cost a lot of money.

I think it depends. If the building is important for history or culture, we should keep it. But if it's just old and not special, maybe it's okay to build something new.
