Then,

his chores being all dispatched, he caught
another brace of men to make his breakfast,
and whisked away his great door slab
to let his sheep go through—but he, behind,
reset the stone as one would cap a quiver.

the use of the epic simile in this excerpt readers understand that

the cyclops has eaten another bunch of odysseus’s men.
odysseus and his men are still trapped inside the cave.
the enormous stone is easily and routinely moved by the giant cyclops.
the cyclops takes his sheep out to pasture with him in the mornings

1. this would be first person. it would be like "i walked home from school today" they are the narrator of the story and is a character as well.

2. first person because they used the word "i" in the quote.

3. i'm really not sure about this one i'm really sorry i never read it so i wouldn't know how to answer it. 

4. it would be character vs. society because everyone he meets there is always a conflict of some sort because he's stuck in his daydream.

5. it would be sadness at the loss of youth because the title itself tells us it's about age so it couldn't be about regret. and the tone just sounds sad, not angry. 

i hope this !
