Why do you think that "few real knights could live up to the ideals of chivalry"? Cite evidence from the text to support your conclusions.

Hello. You did not enter the necessary text for the question to be answered, but I can help you by saying that few knights would be able to live according to the ideals of chivalry, because these ideals had many rules and required great sacrifices from the knights.

Explanation:

Knights had to live under a strict code that provided several commandments that should be strictly followed by those who wished to be knights. These commandments could be very difficult to keep, because they promoted that some sacrifice on the part of the knights was carried out and often went against their will and their personal availability.

In other words, in a certain way, being a knight could be a burden and therefore many people would not be able to remain in that social group.
