I’m working on a literature writing question and need an explanation and answer to help me learn.

Now that you have read the entirety of Sir Gawain, consider how he measures up to the qualities represented on his shield. Remember that the pentangle represents, among other things, “friendship and fraternity with fellow men,/ purity and politeness that impressed at all times, / and pity” (2.652-4). Using evidence from the poem, argue that he does or does not uphold one of these qualities.
