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_11, x_11 is a bartender or x_11 will read a book. For all x_11, x_11 is not a bartender.
For all x_11, x_11 will read a book can be inferred via the universal disjunctive syllogism rule.
