Consider the following premises. For all x_6, if x_6 were rich, then x_6 is sleeping. For all x_6, x_6 is rich or x_6 is a carpenter. For all x_6, if x_6 were a carpenter, then x_6 is sleeping. There is at least one x_6 for which x_6 is an electrician. Can we infer the following from them? For all x_6, x_6 is not an electrician.
 From the fact that for all x_6, if x_6 were rich, then x_6 is sleeping, that for all x_6, if x_6 were a carpenter, then x_6 is sleeping, and that for all x_6, x_6 is rich or x_6 is a carpenter we can infer that for all x_6, x_6 will sleep. From the fact that there is at least one x_6 for which x_6 is an electrician, and that for all x_6, x_6 will sleep we can infer that there is at least one x_6 for which x_6 is an electrician and x_6 will sleep. Finally, from the fact that there is at least one x_6 for which x_6 is an electrician and x_6 will sleep we can infer that there is at least one x_6 for which x_6 is an electrician, which contradicts that For all x_6, x_6 is not an electrician. Therefore, the answer is no.
