What is the passage? :) Please provide more information.
I would have to read the poem, but a lot of symbolism can be used for a paper bag. I'd say it's pretty important but, again, I woud probably need to read the poem first.

Just create a question that supports evidence from the text such as, where did graciella get the radio jammer?
