What special “privileges” did York enjoy that others like him during this time period did not?

Hello. You did not enter the text to which this question refers, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.

A privilege is a benefit, which facilitates an individual's life in relation to any factor or element in any social, economic and political field. In this case, to answer your question, you should look in the text you have, what benefits York had, which made his life easier in some way and that the people who lived with him did not have access.
