Consider the following premises. For all x_8, x_8 will play tennis if and only if x_8 will take a plane. For all x_8, if x_8 plays tennis, then x_8 is a lawyer. For all x_8, if x_8 were a lawyer, then x_8 is playing a game. Can we infer the following from them? For all x_8, if x_8 takes a plane, then x_8 is playing a game.
 From the fact that for all x_8, x_8 will play tennis if and only if x_8 will take a plane we can infer that for all x_8, if x_8 takes a plane, then x_8 is playing tennis. From the fact that for all x_8, if x_8 takes a plane, then x_8 is playing tennis, and that for all x_8, if x_8 plays tennis, then x_8 is a lawyer we can infer that for all x_8, if x_8 takes a plane, then x_8 is a lawyer. Finally, from the fact that for all x_8, if x_8 takes a plane, then x_8 is a lawyer, and that for all x_8, if x_8 were a lawyer, then x_8 is playing a game we can infer that for all x_8, if x_8 takes a plane, then x_8 is playing a game. Therefore, the answer is yes.
