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: exists x_22: ~P_22(x_22). forall x_22: R_14(x_22) <-> Q_12(x_22). forall x_22: Q_14(x_22) -> R_14(x_22). forall x_22: Q_22(x_22) -> Q_14(x_22). forall x_22: P_22(x_22) or Q_22(x_22).
forall x_22: Q_22(x_22) -> R_14(x_22) can be inferred via the universal transitivity rule. exists x_22: Q_22(x_22) can be inferred via the existential disjunctive syllogism rule. forall x_22: R_14(x_22) -> Q_12(x_22) can be inferred via the universal biconditional elimination rule. forall x_22: Q_12(x_22) -> R_14(x_22) can be inferred via the universal biconditional elimination rule.
