Consider the following premises. There is at least one x_9 for which x_9 will play a game if and only if x_9 will drink water. For all x_9, x_9 will play tennis if and only if x_9 will play squash. For all x_9, x_9 will not play tennis. For all x_9, if x_9 drives a car, then x_9 is playing squash. For all x_9, if x_9 drinks water, then x_9 is driving a car. Can we infer the following from them? For all x_9, x_9 will play a game.
 From the fact that for all x_9, if x_9 drinks water, then x_9 is driving a car, and that for all x_9, if x_9 drives a car, then x_9 is playing squash we can infer that for all x_9, if x_9 drinks water, then x_9 is playing squash. From the fact that for all x_9, x_9 will play tennis if and only if x_9 will play squash, and that for all x_9, x_9 will not play tennis we can infer that for all x_9, x_9 will not play squash. From the fact that for all x_9, if x_9 drinks water, then x_9 is playing squash, and that for all x_9, x_9 will not play squash we can infer that for all x_9, x_9 will not drink water. Finally, from the fact that there is at least one x_9 for which x_9 will play a game if and only if x_9 will drink water, and that for all x_9, x_9 will not drink water we can infer that there is at least one x_9 for which x_9 will not play a game, which contradicts that For all x_9, x_9 will play a game. Therefore, the answer is no.
