he paid "for"
He paid for the arrows.
One answer says para and the other por. Which is correct. "por" sounds better to me--but I don't have a reason for using it. Thank you.

Por. Any exchange is marked by 'por', not 'para'.
Here, you are basically saying: He paid in exchange of the arrows. So 'por' should work.
Or neither, since pagar can mean "to pay for..."
por.
