1. There are two steps for evaluating argument, the first step is to determine the logical strength of the argument and the second step is to determine the truth value of the premises. Please discuss whether this 2-step evaluation is good. 2. Informal fallacy can be divided into 4 classes: inconsistence, irrelevancy, insufficiency and inappropriate presupposition. It is called "4I" classification. Discuss whether it Is a good classification.
