## The Attempt at a Solution

My thing is there way to do this...I don't know if this makes sense but i think it is neither because they have 2 variables that don't exist a regular Q and a regular T....I am somewhat new at this and I think because there isn't regular Q and T I think this statement is neither a tautology or contradiction because the statement has a ~Q and a ~T. PLEASE HELP....
