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 y_3: W(y_3) <-> S_2(y_3). forall y_3: W(y_3) or ~Q(y_3). forall y_3: ~S_2(y_3).
forall y_3: Q(y_3) -> W(y_3) can be inferred via the universal rewriting rule. forall y_3: W(y_3) -> S_2(y_3) can be inferred via the universal biconditional elimination rule. forall y_3: S_2(y_3) -> W(y_3) can be inferred via the universal biconditional elimination rule. forall y_3: ~W(y_3) can be inferred via the universal biconditional elimination rule.
