What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_4: ~Q_4(x_4) or T_3(x_4). forall x_4: P_4(x_4) or Q_4(x_4). forall x_4: ~P_4(x_4) or Q(x_4). exists x_4: T_3(x_4) -> Q_2(x_4). forall x_4: Q(x_4) -> Q_2(x_4).
forall x_4: Q_4(x_4) or Q(x_4).
