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, if x_5 goes running, then x_5 is taking a plane. For all x_5, x_5 will read a book and x_5 will play tennis. For all x_5, x_5 will go running.
For all x_5, x_5 will take a plane can be inferred via the universal modus ponens rule. For all x_5, x_5 will read a book can be inferred via the universal simplification rule. For all x_5, x_5 will play tennis can be inferred via the universal simplification rule.
