Answer: B. The ancient Greeks valued community.
The Cyplops's island embodies the fears and dislikes of Greek people. As they are meant to be savages that differ greatly from Greeks, they represent everything Greeks are not. The passage states that the inhabitants of the Cyclops's island do not care about their neighbours, about the laws of a community, about a council or about social interaction. The fact that the text highlights these elements shows that the Greeks valued community and social interaction.
