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_6 for which x_6 will read a book or x_6 will work. For all x_6, if x_6 works, then x_6 is sleeping. For all x_6, x_6 will not read a book or x_6 will go running. For all x_6, x_6 will go running if and only if x_6 will sleep.
There is at least one x_6 for which x_6 will work or x_6 will go running. For all x_6, if x_6 goes running, then x_6 is sleeping. For all x_6, if x_6 sleeps, then x_6 is running.
