What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_6: T(x_6) or Q_1(x_6). forall x_6: Q_1(x_6) -> Q_6(x_6). forall x_6: R_6(x_6) <-> T(x_6). exists x_6: Q_6(x_6) -> R_6(x_6).
exists x_6: Q_1(x_6) -> R_6(x_6). forall x_6: R_6(x_6) -> T(x_6). forall x_6: T(x_6) -> R_6(x_6).
