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_8 for which if x_8 were a police officer, then x_8 is a soldier. For all x_8, if x_8 were a nurse, then x_8 is an office clerk. For all x_8, if x_8 plays tennis, then x_8 is an office clerk. For all x_8, if x_8 were a soldier, then x_8 is not an office clerk. For all x_8, x_8 will play tennis or x_8 is a nurse.
