Consider each of the following argumentative passages and indicate (i) whether it commits a fallacy and (ii) whether, specifically, it commits an argument against the person fallacy. (Note: It is possible for a single argument to commit more than one type of fallacy. Also, if an argument commits a different fallacy altogether, indicate that it does commit a fallacy but not the "argument against the person" fallacy.)
