What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_8: ~Q_8(x_8) or R_6(x_8). forall x_8: R_8(x_8) -> R_4(x_8). forall x_8: T(x_8) -> ~R_4(x_8). forall x_8: R_6(x_8) -> R_4(x_8). forall x_8: ~P_8(x_8) or R_8(x_8). forall x_8: P_8(x_8) or Q_8(x_8).
forall x_8: Q_8(x_8) or R_8(x_8).
