Consider the following premises. For all x_10, if x_10 were happy, then x_10 is sleeping. For all x_10, x_10 will take a plane. For all x_10, x_10 is happy. For all x_10, if x_10 takes a plane, then x_10 is drinking water. Can we infer the following from them? There is at least one x_10 for which neither x_10 will drink water nor x_10 is an electrician.
 From the fact that for all x_10, if x_10 were happy, then x_10 is sleeping, and that for all x_10, x_10 is happy we can infer that for all x_10, x_10 will sleep. From the fact that for all x_10, if x_10 takes a plane, then x_10 is drinking water, and that for all x_10, x_10 will take a plane we can infer that for all x_10, x_10 will drink water. From the fact that for all x_10, x_10 will drink water, and that for all x_10, x_10 will sleep we can infer that for all x_10, x_10 will drink water and x_10 will sleep. From the fact that for all x_10, x_10 will drink water and x_10 will sleep we can infer that for all x_10, x_10 will drink water. Finally, from the fact that for all x_10, x_10 will drink water we can infer that for all x_10, x_10 will drink water or x_10 is an electrician, which contradicts that There is at least one x_10 for which neither x_10 will drink water nor x_10 is an electrician. Therefore, the answer is no.
