Ultural Foundations Essay on Sir Gawain and the Green Knight

The essay that I would like you to write on is on the book Sir Gawain and the Green KnightWe use a plagiarism website called turnitin.com so PLEASE do not plagiarize. Below are the instructions for the paper that my professor gave the class:
Write a close reading of a passage of your own choice from Sir Gawain and the Green Knight. The passage should be about 40 lines (or less) long, and should not be one we discussed extensively in class. Be sure to include page or line numbers so that I can find it easily.

Your reading should provide an account of:

EITHER how this passage enables us to say something about characterisation (not just character or personality), i.e., how its author creates a self or identity for one of the characters or for the poemas implied narrator.

OR what we might learn about the culture that helped generate the poem.

Dont attempt to write a general essay on your chosen passage or waste words on plot summary. Avoid a line-by-line commentary: you should arrange your observations into arguments.

You might wish to comment on:

a? the relation of the passage to the structure and concerns of the rest of the text
