Answer:
trade and colonization
Step-by-step explanation:
The influence or expansion of the Greek city-states around the Aegean is known as the Aegean civilization.
Aegean civilization was increased by trade and colonization of Greek city-states. Sea Trade was a fundamental aspect of the ancient Greek as they had few natural resources and that helped them in territorial expansion.
The Greek population started Colonization or large-scale population movements to get resources and trading helped them to form colonies in other regions such as around Aegean.
Hence, the correct answer is "trade and colonization".
