5. Provide a derivation for the following argument. You may use either basic or derived rules. Hint: The derivation can be completed in seven lines as a direct derivation with no sub- derivations using one basic rule and two derived rules. (It can be done in 5 lines if you just cite the premises rather than bringing them into the derivation.) As an indirect derivation using no derived rules, it takes about twenty lines and includes at least one subderivation. ((Q V P) → R) → (~ P → (R^ Q)) . PV (RΛQ)
