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_16, x_16 will drive a car. For all x_16, x_16 is a cashier or x_16 will play tennis. Elisabeth is listening to a song. For all x_16, if x_16 were a cashier, then x_16 is drinking water. For all x_16, if x_16 plays tennis, then x_16 is drinking water.
For all x_16, x_16 will drink water can be inferred via the universal disjunction elimination rule.
