Answer:
A name can establish ethos with its title (ex: President or Doctor) or with its status. Like if you heard the name "John F. Kennedy" it already establishes credibility because of his position as President, and so readers already believe he is a reliable speaker. So if William Wallace was a well-known person, his name establishes credibility because people already know of him and respect him, and so believe he will be a reliable speaker.
Explanation:
I'm not sure who William Wallace is or the context, but hope this helps!
