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, x_5 is an electrician or x_5 is not rich. For all x_5, if x_5 were an electrician, then x_5 is rich.
For all x_5, if x_5 were rich, then x_5 is an electrician can be inferred via the universal rewriting rule.
