What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: forall x_11: P_6(x_11) or T(x_11). forall x_11: Q_7(x_11) -> P_11(x_11). forall x_11: P_11(x_11) <-> T(x_11). forall x_11: P_11(x_11) -> Q_7(x_11). forall x_11: ~P_6(x_11) or Q_7(x_11).
forall x_11: T(x_11) or Q_7(x_11) can be inferred via the universal resolution rule. forall x_11: Q_7(x_11) <-> P_11(x_11) can be inferred via the universal biconditional introduction rule. forall x_11: P_11(x_11) <-> Q_7(x_11) can be inferred via the universal biconditional introduction rule. forall x_11: P_11(x_11) -> T(x_11) can be inferred via the universal biconditional elimination rule. forall x_11: T(x_11) -> P_11(x_11) can be inferred via the universal biconditional elimination rule.
