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 drinks water, then x_5 is working. There is at least one x_5 for which x_5 will play tennis. For all x_5, x_5 will work or x_5 will not play tennis.
For all x_5, if x_5 plays tennis, then x_5 is working can be inferred via the universal rewriting rule.
