Thomas Malory, the author of "How Arthur Was Chosen King," was from England. Which phrase from paragraph 1 of the passage reveals cultural norms of Malory's time?

So upon New Year's Day, when the service was done, the barons rode unto the field, some to joust and some to tourney, and so it happened that Sir Ector, that had great livelihood about London, rode unto the jousts, and with him rode Sir Kay his son, and young Arthur that was his nourished brother. Sir Kay lost his sword, for he had left it at his father's lodging, and so he asked young Arthur to ride and retrieve his sword. I will well, said Arthur, and rode fast after the sword, but when he came home, the lady and all were out to see the jousting. Then, Arthur said to himself, I will ride to the churchyard, and take the sword that sticks in the stone, for my brother Sir Kay shall not be without a sword this day.

The phrases:

A. Some to joust and some to tourney.

B. Young Arthur that was his nourished brother.

C. He had left it at his father's lodging.

D. I will ride to the churchyard.
