First I need to see the 2 passages then I can answer it.
The three options that Circe described are
1) to avoid or go through the Chasing Rocks (the voyagers avoided the Chasing Rocks)
2) Pass through Scylla and sacrifice 6 men
3) Pass through Charybdis and hope that the creature won't eat as they pass through
Odysseus chose to go through Scylla and lost 6 men to the creature.
The Narrators growth can contrast naive views with the harsh realities of war.
The choice of this phrase has a paradoxical meaning in a way that Bartleby refuses to do the task asked from him and the expression of this rejection. It is a refusal, but at the same time it is a polite refusal because even when his boss asks again "You will not?", he answers again with "I prefer not". The phrase emphasizes Bartleby's passive resistance. The different use of the phrase, of course could have had a different effect in the story. It might cause a different demonstration and a different ending for the story. The boss could have replied differently because the refusal would be not polite then. However, the choice is intentional because of the development of the story. Therefore, it is suitable in its own way.
