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 will not drink water. For all x_11, x_11 will not drive a car or x_11 will climb a mountain. For all x_11, if x_11 were rich, then x_11 is taking a plane. For all x_11, x_11 will drive a car or x_11 is rich. For all x_11, if x_11 climbs a mountain, then x_11 is taking a plane. For all x_11, x_11 will drink water or x_11 will read a book.
For all x_11, x_11 will read a book can be inferred via the universal disjunctive syllogism rule. For all x_11, x_11 is rich or x_11 will climb a mountain can be inferred via the universal resolution rule.
