What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? There is at least one z_4 for which z_4 will go running if and only if z_4 will cook. For all z_4, z_4 will cook or z_4 will not go running.
For all z_4, if z_4 goes running, then z_4 is cooking. There is at least one z_4 for which if z_4 goes running, then z_4 is cooking. There is at least one z_4 for which if z_4 cooks, then z_4 is running.
