Consider the following premises. For all x_8, x_8 is an astronaut or x_8 is rich. For all x_8, if x_8 were a scientist, then x_8 is climbing a mountain. For all x_8, if x_8 were an electrician, then x_8 is climbing a mountain. For all x_8, x_8 is not rich or x_8 is an electrician. For all x_8, x_8 is not an astronaut or x_8 is a scientist. Can we infer the following from them? There is at least one x_8 for which neither x_8 will climb a mountain nor x_8 is excited.
 From the fact that for all x_8, x_8 is an astronaut or x_8 is rich, and that for all x_8, x_8 is not an astronaut or x_8 is a scientist we can infer that for all x_8, x_8 is rich or x_8 is a scientist. From the fact that for all x_8, x_8 is rich or x_8 is a scientist, and that for all x_8, x_8 is not rich or x_8 is an electrician we can infer that for all x_8, x_8 is a scientist or x_8 is an electrician. From the fact that for all x_8, if x_8 were a scientist, then x_8 is climbing a mountain, that for all x_8, if x_8 were an electrician, then x_8 is climbing a mountain, and that for all x_8, x_8 is a scientist or x_8 is an electrician we can infer that for all x_8, x_8 will climb a mountain. Finally, from the fact that for all x_8, x_8 will climb a mountain we can infer that for all x_8, x_8 will climb a mountain or x_8 is excited, which contradicts that There is at least one x_8 for which neither x_8 will climb a mountain nor x_8 is excited. Therefore, the answer is no.
