Question

Who says the following and why?

"Great renown she wins for herself, no doubt,
great loss to you in treasure." *

Antinous is reprimanding Penelope for her reluctance to marry.
Eurynomus is praising Penelope's virtue.
Mentor is lamenting Penelope's flirtation.
Antinous is warning Telemachus about sailing with Athena.

Answer 1

I'm not sure what story this is
but to answer this correctly you must know who all the characters stated are

Answer 2

So there are 5 characters:
Antinous, Eurynomus, Mentor, Athena, Penelope, and, Telemachus.
You have to know who those people are -
mainly Antinous, Eurynomus, and Mentor though
you have to know who they are
what they do
how they act
Knowing that you would be able to determine who said "Great renown she wins for herself, no doubt,
great loss to you in treasure."
that's just the only logical explanation that I could think of.
