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_10: S_4(x_10) <-> Q(x_10). forall x_10: R_10(x_10) -> R_8(x_10). forall x_10: Q(x_10) -> ~R_8(x_10). forall x_10: ~P_10(x_10) or R_10(x_10). forall x_10: Q_10(x_10) -> R_8(x_10). forall x_10: P_10(x_10) or Q_10(x_10).
forall x_10: Q_10(x_10) or R_10(x_10) can be inferred via the universal resolution rule. forall x_10: S_4(x_10) -> Q(x_10) can be inferred via the universal biconditional elimination rule. forall x_10: Q(x_10) -> S_4(x_10) can be inferred via the universal biconditional elimination rule.
