What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_7: Q_1(x_7) -> W_1(x_7). exists x_7: T(x_7) -> Q_1(x_7). forall x_7: R_1(x_7) or T(x_7). forall x_7: W_1(x_7) or ~R_1(x_7).
exists x_7: T(x_7) -> W_1(x_7). forall x_7: R_1(x_7) -> W_1(x_7).
