What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_9, x_9 will sleep if and only if x_9 will go running. For all x_9, x_9 will not go running. There is at least one x_9 for which x_9 is a police officer if and only if x_9 will sleep.
For all x_9, if x_9 sleeps, then x_9 is running. There is at least one x_9 for which if x_9 were a police officer, then x_9 is sleeping. For all x_9, if x_9 goes running, then x_9 is sleeping. There is at least one x_9 for which if x_9 sleeps, then x_9 is a police officer. For all x_9, x_9 will not sleep.
