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_20, x_20 is an artist or x_20 will not work. Michael is working.
There is at least one x for which x will work can be inferred via the existential generalization rule. For all x_20, if x_20 works, then x_20 is an artist can be inferred via the universal rewriting rule.
