What passage? when you ask a question like this without stating what passage you are talking about, it gets real confusing. i'll give it a crack thoughwhen writing passages with logical fallacies, you need to avoid bad logic, such as "all scientists where jackets. anita has a jacket. therefore, anita is a scientists." just because all scientists have jackets doesn't mean that only scientists where jackets. it's kinda like how all pronouns are nouns but not all nouns are pronouns.
