Consider the following premises. There is at least one x_6 for which x_6 will play a game if and only if x_6 is a politician. For all x_6, if x_6 drinks water, then x_6 is a politician. For all x_6, if x_6 were a police officer, then x_6 is drinking water. For all x_6, if x_6 were a politician, then x_6 is a police officer. For all x_6, x_6 will not drink water. Can we infer the following from them? For all x_6, x_6 will play a game.
 From the fact that for all x_6, if x_6 were a politician, then x_6 is a police officer, and that for all x_6, if x_6 were a police officer, then x_6 is drinking water we can infer that for all x_6, if x_6 were a politician, then x_6 is drinking water. From the fact that for all x_6, if x_6 drinks water, then x_6 is a politician, and that for all x_6, if x_6 were a politician, then x_6 is drinking water we can infer that for all x_6, x_6 will drink water if and only if x_6 is a politician. From the fact that for all x_6, x_6 will drink water if and only if x_6 is a politician, and that for all x_6, x_6 will not drink water we can infer that for all x_6, x_6 is not a politician. Finally, from the fact that there is at least one x_6 for which x_6 will play a game if and only if x_6 is a politician, and that for all x_6, x_6 is not a politician we can infer that there is at least one x_6 for which x_6 will not play a game, which contradicts that For all x_6, x_6 will play a game. Therefore, the answer is no.
