What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_17: R_11(x_17) -> W_1(x_17). forall x_17: P_15(x_17) or Q_15(x_17). exists x_17: ~P_15(x_17) or Q_17(x_17). forall x_17: W_1(x_17) or ~Q_17(x_17). forall x_17: W_1(x_17) -> S(x_17). forall x_17: ~Q_15(x_17) or R_11(x_17).
forall x_17: R_11(x_17) -> S(x_17). exists x_17: Q_15(x_17) or Q_17(x_17). forall x_17: Q_17(x_17) -> W_1(x_17).
