Could you please help me with Main Point questions. What I am most confused by is the "how do I know this" approach. It seems that whenever I ask, "how do I know this?" for a potential conclusion statement I answer the question wrong because I am really not understanding this approach but it seems it would help the most when torn between two possible conclusion statements. Thank you.
