Question

Which of these statements from sir Gawain and the green knight does the green knight say to explain why he visits the court of King Arthur

Answer 1

You didn't provide the possible statements, however, he says that he came there to see whether King Arthur's court is as valiant and honorable as the stories say, so if any of the possible answers fit then that's your answer.

Answer 2

Bertilak, the outsider in green, visits the court of young King Arthur in order to play a Christmas game "For tis Yule and New Year". In his own words we can read in the text that he is in the kingdom "Nay, to fight, in good faith", that "is far from my thought", adds he. However, the fact that no noble knight from that well reputed kingdom dares to accept the challenge is at odds with the fame of Arthur and his brave noble warriors.
