What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? p_8. p_8 -> q_8. forall x_17: Q_17(x_17) -> W(x_17). Q_17(a_7) -> ~q_8. forall x_17: W(x_17) -> Q_17(x_17).
q_8. forall x_17: Q_17(x_17) <-> W(x_17). forall x_17: W(x_17) <-> Q_17(x_17).
