Now the giant cried aloud: "Yield or fight, King Arthur; which will you do? If you fight I shall conquer you, for you have no power to resist me; you will be my prisoner, with no hope of ransom, will lose your land and spend your life in my dungeon with many other brave knights. If you yield I will hold you to ransom, but you must swear to accept the terms I shall offer." What do the giant's words reveal about him?

He is very confident.
He is scared of Arthur.
He is very intelligent.
He is glad to know Arthur.
