What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? W_3(a_12) or q. Q_13(a_12) or ~q. forall x_13: W_3(x_13) -> Q_13(x_13). forall x_13: Q_13(x_13) -> W_3(x_13).
q -> Q_13(a_12). forall x_13: W_3(x_13) <-> Q_13(x_13). forall x_13: Q_13(x_13) <-> W_3(x_13).
