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_6, x_6 will not listen to a song. For all x_6, x_6 will play tennis or x_6 will listen to a song. There is at least one x_6 for which x_6 will climb a mountain. For all x_6, x_6 will not play tennis or x_6 will go running.
For all x_6, x_6 will listen to a song or x_6 will go running can be inferred via the universal resolution rule.
