What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_5, if x_5 takes a plane, then x_5 is climbing a mountain. For all x_5, x_5 will go running if and only if x_5 will take a plane. For all x_5, x_5 will not climb a mountain. For all x_5, x_5 will play a game if and only if x_5 will go running.
For all x_5, x_5 will not take a plane. For all x_5, if x_5 goes running, then x_5 is taking a plane. For all x_5, if x_5 plays a game, then x_5 is running. For all x_5, if x_5 takes a plane, then x_5 is running. For all x_5, if x_5 goes running, then x_5 is playing a game.
