What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_11: ~P_7(x_11). exists x_11: Q_1(x_11) <-> T_3(x_11). forall x_11: P_7(x_11) <-> T(x_11). forall x_11: T_3(x_11) <-> T(x_11).
forall x_11: P_7(x_11) -> T(x_11). forall x_11: T_3(x_11) -> T(x_11). exists x_11: Q_1(x_11) -> T_3(x_11). forall x_11: T(x_11) -> P_7(x_11). forall x_11: T(x_11) -> T_3(x_11). exists x_11: T_3(x_11) -> Q_1(x_11). forall x_11: ~T(x_11).
