Answer:
B. Be directly involved in a government
Step-by-step explanation:
The people living in polis had obligations that were much different in few aspects than at any other place in the world. It was not all people, but only the elderly men, which had an obligation to be part of the council, or rather the government of the polis. As they were considered as the most experienced, the ones that had the most knowledge, and were wisest, they had to serve in the decision making and politics of the polis. This was actually the initial set up for the further development of the democracy.
