What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: For all x_5, if x_5 goes running, then x_5 is a nurse. For all x_5, if x_5 were a nurse, then x_5 is playing squash. For all x_5, if x_5 were a cashier, then x_5 is driving a car. For all x_5, x_5 is a cashier or x_5 will go running. For all x_5, if x_5 plays squash, then x_5 is driving a car.
For all x_5, if x_5 goes running, then x_5 is playing squash can be inferred via the universal transitivity rule. For all x_5, if x_5 were a nurse, then x_5 is driving a car can be inferred via the universal transitivity rule.
