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_14, if x_14 climbs a mountain, then x_14 is a sailor. For all x_14, x_14 will play tennis. If John reads a book, then Jennifer is not a sailor. For all x_14, if x_14 plays tennis, then x_14 is climbing a mountain.
For all x_14, x_14 will climb a mountain can be inferred via the universal modus ponens rule. For all x_14, if x_14 plays tennis, then x_14 is a sailor can be inferred via the universal transitivity rule.
