Use the truth table method to evaluate the following statements/sets of state-ments. For each, say whether the statement/set is consistent, inconsistent,Contingent, a tautology, or a contradiction. (10 pts each) \text

{ 11. } p \vee q ; \neg p 12(n \wedge q) \vee r ; \neg q \wedge \neg r \text { 13. } \neg p \wedge \neg q ; p \Longleftrightarrow q \text { 14. }((p \Longrightarrow q) \wedge(q \Longrightarrow r)) \Longrightarrow(p \Longrightarrow r)
