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: Joseph is driving a car. For all x_10, if x_10 sleeps, then x_10 is drinking water. For all x_10, x_10 will sleep.
For all x_10, x_10 will drink water can be inferred via the universal modus ponens rule.
