What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_14: P_14(x_14) -> Q_14(x_14). ~P_14(a_13). forall x_14: Q_14(x_14) -> P_14(x_14). q_1.
~P_14(a_13) and q_1. q_1 and ~P_14(a_13). forall x_14: P_14(x_14) <-> Q_14(x_14). forall x_14: Q_14(x_14) <-> P_14(x_14).
