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_7, x_7 is bored or x_7 will not climb a mountain. There is at least one x_7 for which if x_7 were bored, then x_7 is not running. For all x_7, x_7 will go running.
There is at least one x_7 for which x_7 is not bored can be inferred via the existential modus tollens rule. For all x_7, if x_7 climbs a mountain, then x_7 is bored can be inferred via the universal rewriting rule.
