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: John is a soldier. If it is cloudy, then Michael is a musician. For all x_14, if x_14 takes a plane, then x_14 is a musician. It is cloudy or Michael is taking a plane.
If Michael plays a game, then it is cloudy can be inferred via the rewriting rule.
