What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_6: T_1(x_6) -> ~Q(x_6). forall x_6: P_6(x_6) -> U(x_6). forall x_6: P_6(x_6). forall x_6: Q(x_6).
forall x_6: U(x_6). exists x_6: ~T_1(x_6). forall x_6: P_6(x_6) and Q(x_6). forall x_6: Q(x_6) and P_6(x_6).
