What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_6: P_6(x_6) or Q_6(x_6). forall x_6: R_6(x_6) -> R_3(x_6). forall x_6: Q_6(x_6) -> R_3(x_6). forall x_6: ~P_6(x_6) or R_6(x_6). forall x_6: Q_2(x_6).
forall x_6: Q_6(x_6) or R_6(x_6).
