Final answer:
Sir Gawain, King Arthur, Robin Hood, and the husband in "Get Up and Bar the Door" each demonstrated different levels of chivalry in their actions.
Step-by-step explanation:
Sir Gawain showed chivalry by accepting the lady's gift, as it was a sign of respect. However, he failed to maintain the code when he hid the green sash from his host.
King Arthur displayed chivalry by pulling the sword from the stone, proving his worthiness. His actions aligned with the code of chivalry, as he upheld justice and honor.
Robin Hood's actions contradicted chivalry, as he stole from the rich and gave to the poor, challenging the authority of the upper class.
In "Get Up and Bar the Door," the husband failed to act with chivalry when he refused to close the door for his wife, as it was seen as his duty to protect her.
