What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? q -> r_3. forall x_14: P_14(x_14) <-> Q_14(x_14). r_3 -> Q_14(a_10).
q -> Q_14(a_10). forall x_14: P_14(x_14) -> Q_14(x_14). forall x_14: Q_14(x_14) -> P_14(x_14).
