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_11(x_11) -> R(x_11). forall x_11: P_6(x_11) or T(x_11). forall x_11: ~P_6(x_11) or R(x_11). forall x_11: P_11(x_11) <-> T(x_11). forall x_11: R(x_11) -> P_11(x_11).
forall x_11: T(x_11) or R(x_11). forall x_11: P_11(x_11) <-> R(x_11). forall x_11: R(x_11) <-> P_11(x_11). forall x_11: P_11(x_11) -> T(x_11). forall x_11: T(x_11) -> P_11(x_11).
