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_10 for which x_10 will work if and only if x_10 will go running. For all x_10, x_10 is a nurse if and only if x_10 will go running. For all x_10, x_10 is a nurse.
For all x_10, if x_10 were a nurse, then x_10 is running. There is at least one x_10 for which if x_10 works, then x_10 is running. For all x_10, if x_10 goes running, then x_10 is a nurse. There is at least one x_10 for which if x_10 goes running, then x_10 is working.
