Final answer:
Alcinous demonstrates good xenia, or hospitality, by c. warmly welcoming Odysseus after Demodocus' tale, which aligns with Greek cultural norms of treating guests with kindness and respect.
Step-by-step explanation:
The question refers to how Alcinous, the king of the Phaeacians in Homer's epic poem The Odyssey, shows good xenia (hospitality) after hearing the minstrel Demodocus perform a tale that deeply moves Odysseus.
The correct answer to the question is: c. Alcinous welcomes Odysseus warmly. After Demodocus sings of the Trojan War, Odysseus, who is deeply touched by the song, is noticed by Alcinous.
To show good xenia, Alcinous then ensures Odysseus is well taken care of, acknowledging his emotional state and being a gracious host by offering him assistance to return home and providing him with gifts.
This is an example of the hosts' duty to be kind and welcoming to guests, especially strangers, which was a sacred norm in ancient Greek culture.
