What was the main purpose? What did the writer (or speaker) want the audience to learn? For example, did he or she want to influence the actions of audience members, get them to think differently about the criteria or standards they should use when judging subjects of this kind, get them to look at the subject in a new way, or accomplish some other purpose?
