Consider the following premises. For all x_9, x_9 will play squash if and only if x_9 is a bartender. There is at least one x_9 for which if x_9 plays a game, then x_9 is an electrician. For all x_9, x_9 is not an electrician. For all x_9, x_9 is a bartender if and only if x_9 will play a game. Can we infer the following from them? For all x_9, x_9 will play squash.
 From the fact that there is at least one x_9 for which if x_9 plays a game, then x_9 is an electrician, and that for all x_9, x_9 is not an electrician we can infer that there is at least one x_9 for which x_9 will not play a game. From the fact that for all x_9, x_9 is a bartender if and only if x_9 will play a game, and that there is at least one x_9 for which x_9 will not play a game we can infer that there is at least one x_9 for which x_9 is not a bartender. Finally, from the fact that for all x_9, x_9 will play squash if and only if x_9 is a bartender, and that there is at least one x_9 for which x_9 is not a bartender we can infer that there is at least one x_9 for which x_9 will not play squash, which contradicts that For all x_9, x_9 will play squash. Therefore, the answer is no.
