Knowledge: The quality of air in Montreal is very bad due to the wildfires happening each year and so many people have lung issues. On the other hand, Miami was selected to have the worst pollution in 2020.

Conversation:
I'd love to vacation in Florida some day, do you know much about Florida?
I know that Tallahassee is the capital. Is there anything else you'd like to know?
That's cool, I've heard oranges are really crucial to Florida's economy, does that sound right to you?
I don't know how crucial oranges are to the economy, but I know that in the north the climate is subtropical, and it becomes tropical to the south.
That makes sense, the Florida climate does seem very good for growing stuff, Do you know anything about Miami? I was thinking of going there.
I know that Miami is an urban area, and is the most  populous of the urban areas in Florida
Interesting, I didn't know Miami had so many people. Do you know the quality of air in Miami?

Response: Hmm, the quality of air there is bad as it was selected to have the worst pollution in 2020.
