Read the excerpt from sir gawain and the green knight, and complete the paragraph that follows.

but finding none that would carp with him, he exclaims, "what! is this arthur's house, the fame of which has spread through so many realms? forsooth, the renown of the round table is overturned by the word of one man's speech, for all tremble for dread without a blow being struck! " with this he laughed so loud that arthur blushed for very shame, and waxed as wroth as the wind. "i know no man," he says, "that is aghast at thy great words. give me now thy axe and i will grant thee thy request! "

these lines tell us that the green knight mocked the knights of arthur’s court for being cowardly and not accepting his challenge. king arthur stepped up to accept the challenge himself, but gawain does not let his king suffer such agony, humiliation, arrogance, custom ,and accepts the potentially fatal challenge. by this act, gawain upholds the mode ,dictate, code, value of chivalry.
