I want to know the answer to the following question:
How many of the Australian Football League's teams are based in the Melbourne metropolitan area?
All the background I'm provided with is that "Nine of the League's teams are based in the Melbourne metropolitan area: Carlton, Collingwood, Essendon, Hawthorn, Melbourne, North Melbourne, Richmond, St Kilda, and Western Bulldogs.". Is that enough to answer the question?
Answer: yes
