What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_10: ~P_10(x_10) or R_10(x_10). forall x_10: W_1(x_10) <-> Q_7(x_10). forall x_10: Q_7(x_10) <-> R_10(x_10). exists x_10: P_10(x_10) or W_1(x_10).
exists x_10: W_1(x_10) or R_10(x_10). forall x_10: W_1(x_10) -> Q_7(x_10). forall x_10: Q_7(x_10) -> R_10(x_10). forall x_10: Q_7(x_10) -> W_1(x_10). forall x_10: R_10(x_10) -> Q_7(x_10).
