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_2 for which x_2 is an electrician. For all x_2, x_2 will read a book or x_2 is not an electrician.
For all x_2, if x_2 were an electrician, then x_2 is reading a book can be inferred via the universal rewriting rule.
