What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_2, if x_2 were a taxi driver, then x_2 is taking a plane. For all x_2, x_2 will take a plane or x_2 will not play a game. There is at least one x_2 for which x_2 is a taxi driver or x_2 will play a game.
For all x_2, if x_2 plays a game, then x_2 is taking a plane.
