From sir gawande and the green knight what does the description of the attire of the strange man say of his social status? and in guise all of green, the gear and the man; a coat cut close, that caught close to his sides, and mantle to match, made with a lining of furs cut and fitted- the fabric was noble

i believe it is the first choice (1.)

because the major theme is(“both the wild and civilization have rules.”)

and also as u said,( based on what buck learns within the call of the wild, "both the wild and civilization have rules".this is true of humans within society as well.

it shaped life in both positive and negative ways. the positive sides of the medieval government was that it had a very strong and military. the citizens felt safer because of the high military interference. the citizens also had a positive attitude towards the artisan class and gave a huge respect to them. there is also a negative side of the government where the government would use the military too much on its citizens which created a sense of autocracy. it was oppressive to the peasants especially to the women.
