Q

Note about Arguments

A

No argument can have more than one conclusion. Of course, sometimes we do find passages with more than one conclusion. There are two types of cases: (1) when more than one conclusion is drawn from the same set of premises (i.e., when the same premises contain two different arguments), (2) when we chain arguments together so that a single statement serves as both a premise and conclusion.
