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 x_7 for which if x_7 were a police officer, then x_7 is cooking. For all x_7, if x_7 cooks, then x_7 is a police officer. For all x_7, x_7 is not a police officer.
For all x_7, x_7 will not cook. There is at least one x_7 for which x_7 is a police officer if and only if x_7 will cook. There is at least one x_7 for which x_7 will cook if and only if x_7 is a police officer.
