What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? If Jessica goes running, then Michael is a musician. For all x_6, x_6 will take a plane or x_6 will listen to a song. If Thomas listens to a song, then Michael is a musician. Thomas is not taking a plane or Jessica is running.
Nothing can be inferred from these premises.
