What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_19: W(x_19) <-> Q_16(x_19). forall x_19: ~Q_16(x_19). forall x_19: ~P_19(x_19) or T(x_19). forall x_19: P_19(x_19) or W(x_19). forall x_19: R_3(x_19).
forall x_19: W(x_19) or T(x_19). exists x_19: W(x_19) -> Q_16(x_19). exists x_19: Q_16(x_19) -> W(x_19). exists x_19: ~W(x_19).
