I want to know the answer to the following question:
The Free Hanseatic City of Bremen includes which two cities?
All the background I'm provided with is that "With an emphasis on geographical conditions, Berlin and Hamburg are frequently called Stadtstaaten (city-states), as is the Free Hanseatic City of Bremen, which in fact includes the cities of Bremen and Bremerhaven.". Is that enough to answer the question?
Answer: yes
