What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_8, x_8 is a taxi driver if and only if x_8 will take a plane. For all x_8, x_8 is a taxi driver or x_8 will not play a game. For all x_8, x_8 will play a game or x_8 will take a plane.
For all x_8, if x_8 plays a game, then x_8 is a taxi driver. For all x_8, if x_8 were a taxi driver, then x_8 is taking a plane. For all x_8, if x_8 takes a plane, then x_8 is a taxi driver.
