Consider the following premises. For all x_10, x_10 is a musician or x_10 will play a game. For all x_10, if x_10 plays a game, then x_10 is a scientist. For all x_10, x_10 is not a musician or x_10 is a sailor. For all x_10, x_10 is a scientist or x_10 is not a sailor. Can we infer the following from them? For all x_10, x_10 is a scientist or x_10 is a politician.
 From the fact that for all x_10, x_10 is a musician or x_10 will play a game, and that for all x_10, x_10 is not a musician or x_10 is a sailor we can infer that for all x_10, x_10 will play a game or x_10 is a sailor. From the fact that for all x_10, x_10 is a scientist or x_10 is not a sailor we can infer that for all x_10, if x_10 were a sailor, then x_10 is a scientist. From the fact that for all x_10, if x_10 plays a game, then x_10 is a scientist, that for all x_10, if x_10 were a sailor, then x_10 is a scientist, and that for all x_10, x_10 will play a game or x_10 is a sailor we can infer that for all x_10, x_10 is a scientist. Finally, from the fact that for all x_10, x_10 is a scientist we can infer that for all x_10, x_10 is a scientist or x_10 is a politician. Therefore, the answer is yes.
