Consider the following premises. There is at least one x_15 for which x_15 is a taxi driver or x_15 is not a poet. For all x_15, x_15 is not a taxi driver. For all x_15, x_15 is a poet or x_15 will not play a game. Can we infer the following from them? There is at least one x_15 for which x_15 will not play a game.
 From the fact that there is at least one x_15 for which x_15 is a taxi driver or x_15 is not a poet we can infer that there is at least one x_15 for which if x_15 were a poet, then x_15 is a taxi driver. From the fact that there is at least one x_15 for which if x_15 were a poet, then x_15 is a taxi driver, and that for all x_15, x_15 is not a taxi driver we can infer that there is at least one x_15 for which x_15 is not a poet. From the fact that for all x_15, x_15 is a poet or x_15 will not play a game we can infer that for all x_15, if x_15 plays a game, then x_15 is a poet. Finally, from the fact that for all x_15, if x_15 plays a game, then x_15 is a poet, and that there is at least one x_15 for which x_15 is not a poet we can infer that there is at least one x_15 for which x_15 will not play a game. Therefore, the answer is yes.
