I’m interested

#help why is the or in the first sentence being treated as an and in JY's explanation? If the application satisfies one of the or's in the principle, then why does the second or 'criticize self' need to be there to complete the argument? (pt 77 sec 2 #21)

#help I initially tried to diagram the second sentence. I saw who as indicating sufficient and may indicating necessary and made a "some" statement because the conditional language seemed weak. How do I avoid this mistake in the future? Where can I find good examples of some premises?
