It can be said that chivalry affected the characters when the Knights exhibited their behavior. The Green Knight challenged the knights´honor and so Sir Gawain asked the King to accept that challenge. It seems that he wanted to show his loyalty (value of Chivalry) to King Arthur. Later on, the Green Knight promised to keep his word (value of Chivalry).
<span> The knights at Camelot exhibit behaviors that reflect chivalry. When the Green Knight arrives, he challenges the knights' honor. Sir Gawain asks King Arthur to let him accept the challenge. He wants to show his loyalty to the king, which is a value of chivalry. Then, the Green Knight makes him promise to keep his word, which is another value of chivalry. If Sir Gawain does not keep his promise, the Green Knight says, he will be a coward.</span>
I believe the answer would be Bill Gates. An appositive is a noun that renames a noun right beside it. In this case, "Bill Gates" is renaming "One of the richest men in the world."
