What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x: T(x) -> S(x). forall x: P_2(x). forall x: P(x) -> S(x). forall x: P_4(x) or P(x). forall x: ~P_4(x) or T(x). forall x: P_2(x) -> W_3(x).
forall x: W_3(x). forall x: P(x) or T(x).
