mLine 7:
Line 7: − One could as easily argue that all undergraduates are also sophomores, and the argument would be equally valid--or invalid in this case. However, one can establish the truth of the conclusion in another way--in this case, by [[definition]].+
this is more confusing than helpful
#Therefore, all sophomores are undergraduates.

Logical fallacy ''is not'' the same as lying. A ''lie'' in logic is a premise that one offers while knowing that it is false. False premises can still be part of valid arguments, but conclusions having false premises to support them will be unreliable. A logical fallacy, then, is a flawed argumental structure, one that would lead to an unreliable conclusion even when its premises are true.
