Consider the following premises. For all x_9, if x_9 drinks water, then x_9 is playing squash. For all x_9, if x_9 were a soldier, then x_9 is drinking water. There is at least one x_9 for which x_9 will not play squash. For all x_9, x_9 is a soldier or x_9 is a carpenter. Can we infer the following from them? For all x_9, x_9 is not a carpenter.
 From the fact that for all x_9, if x_9 were a soldier, then x_9 is drinking water, and that for all x_9, if x_9 drinks water, then x_9 is playing squash we can infer that for all x_9, if x_9 were a soldier, then x_9 is playing squash. From the fact that for all x_9, if x_9 were a soldier, then x_9 is playing squash, and that there is at least one x_9 for which x_9 will not play squash we can infer that there is at least one x_9 for which x_9 is not a soldier. Finally, from the fact that for all x_9, x_9 is a soldier or x_9 is a carpenter, and that there is at least one x_9 for which x_9 is not a soldier we can infer that there is at least one x_9 for which x_9 is a carpenter, which contradicts that For all x_9, x_9 is not a carpenter. Therefore, the answer is no.
