Consider the following premises. For all x_8, x_8 is a server if and only if x_8 will drink water. For all x_8, if x_8 plays a game, then x_8 is drinking water. For all x_8, if x_8 were a server, then x_8 is playing a game. Can we infer the following from them? There is at least one x_8 for which if is not true that x_8 will play a game if and only if x_8 is a server.
 From the fact that for all x_8, x_8 is a server if and only if x_8 will drink water we can infer that for all x_8, if x_8 drinks water, then x_8 is a server. From the fact that for all x_8, if x_8 plays a game, then x_8 is drinking water, and that for all x_8, if x_8 drinks water, then x_8 is a server we can infer that for all x_8, if x_8 plays a game, then x_8 is a server. Finally, from the fact that for all x_8, if x_8 plays a game, then x_8 is a server, and that for all x_8, if x_8 were a server, then x_8 is playing a game we can infer that for all x_8, x_8 will play a game if and only if x_8 is a server, which contradicts that There is at least one x_8 for which if is not true that x_8 will play a game if and only if x_8 is a server. Therefore, the answer is no.
