Answer: The first instance in which the reader sees the passage provided is A. when Telemachus invites Athena, disguised as Mentes, to feast in the palace at Ithaca.
Explanation: The passage provided is part of Homer's Odyssey and it appears more than once throughout the poem. However, the first time that the reader sees this passage is in Book 1, when Telemachus receives Pallas Athena at his palace in order to find out what is his father's location. When Athena arrives at the palace, she is disguised as Mentes, the lord of the Taphians. Moreover, Homer includes the passage provided to signal hospitality, a practice that was conceived as an obligation by Ancient Greeks.
