What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_13: S(x_13) or Q_13(x_13). forall x_13: S(x_13) -> T_4(x_13). forall x_13: T(x_13) or ~T_4(x_13). forall x_13: Q_13(x_13) -> T_4(x_13).
forall x_13: T_4(x_13) -> T(x_13). exists x_13: T_4(x_13).
