What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_1: W_2(x_1) -> P_2(x_1). forall x_1: W_2(x_1). forall x_1: U_4(x_1).
forall x_1: P_2(x_1). forall x_1: W_2(x_1) and U_4(x_1). forall x_1: U_4(x_1) and W_2(x_1).
