Consider the following premises. For all x_8, x_8 is a scientist. For all x_8, if x_8 were a scientist, then x_8 is drinking water. For all x_8, x_8 is not happy. There is at least one x_8 for which x_8 is happy or x_8 is an electrician. Can we infer the following from them? For all x_8, either x_8 will drink water or x_8 is an electrician are not true.
 From the fact that there is at least one x_8 for which x_8 is happy or x_8 is an electrician, and that for all x_8, x_8 is not happy we can infer that there is at least one x_8 for which x_8 is an electrician. From the fact that for all x_8, if x_8 were a scientist, then x_8 is drinking water, and that for all x_8, x_8 is a scientist we can infer that for all x_8, x_8 will drink water. Finally, from the fact that for all x_8, x_8 will drink water, and that there is at least one x_8 for which x_8 is an electrician we can infer that there is at least one x_8 for which x_8 will drink water and x_8 is an electrician, which contradicts that For all x_8, either x_8 will drink water or x_8 is an electrician are not true. Therefore, the answer is no.
