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_2: S_4(x_2) -> W_3(x_2). exists x_2: W_3(x_2) -> P(x_2). forall x_2: S_4(x_2) or ~W(x_2).
exists x_2: S_4(x_2) -> P(x_2) can be inferred via the existential transitivity rule. forall x_2: W(x_2) -> S_4(x_2) can be inferred via the universal rewriting rule.
