I want to know the answer to the following question:
What ranking in terms of GDP is Mexico City globally?
All the background I'm provided with is that "According to a study conducted by PwC, Mexico City had a GDP of $390 billion, ranking it as the eighth richest city in the world after the greater metropolitan areas of Tokyo, New York City, Los Angeles, Chicago, Paris, London and Osaka/Kobe (and the richest in the whole of Latin America).". Is that enough to answer the question?
Answer: yes
