I want to know the answer to the following question:
Where have the centers of culture been located for the Grecian world historically ?
All the background I'm provided with is that "Greek colonies and communities have been historically established on the shores of the Mediterranean Sea and Black Sea, but the Greek people have always been centered around the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age.". Is that enough to answer the question?
Answer: no
