What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_13: T_1(x_13) -> Q_7(x_13). forall x_13: ~P_13(x_13). forall x_13: R_4(x_13) <-> Q(x_13). forall x_13: Q_7(x_13) -> Q(x_13). forall x_13: P_13(x_13) or T_1(x_13).
exists x_13: T_1(x_13) -> Q(x_13). forall x_13: T_1(x_13). forall x_13: R_4(x_13) -> Q(x_13). forall x_13: Q(x_13) -> R_4(x_13).
