What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_6: W_2(x_6) <-> Q_6(x_6). forall x_6: W(x_6) -> Q_6(x_6). exists x_6: P_2(x_6) or W(x_6). forall x_6: ~P_2(x_6) or W_2(x_6).
exists x_6: W(x_6) or W_2(x_6). forall x_6: W_2(x_6) -> Q_6(x_6). forall x_6: Q_6(x_6) -> W_2(x_6).
