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: There is at least one x for which if x plays tennis, then x is driving a car. For all x, x will play tennis and x is excited.
For all x, x will play tennis can be inferred via the universal simplification rule. For all x, x is excited can be inferred via the universal simplification rule.
