Consider the following premises. For all x_5, if x_5 works, then x_5 is a politician. There is at least one x_5 for which if x_5 were rich, then x_5 is a politician. For all x_5, x_5 will work and x_5 is curious. Can we infer the following from them? For all x_5, x_5 is not a politician.
 From the fact that for all x_5, x_5 will work and x_5 is curious we can infer that for all x_5, x_5 will work. From the fact that for all x_5, x_5 will work we can infer that for all x_5, x_5 will work or x_5 is rich. Finally, from the fact that for all x_5, if x_5 works, then x_5 is a politician, that there is at least one x_5 for which if x_5 were rich, then x_5 is a politician, and that for all x_5, x_5 will work or x_5 is rich we can infer that there is at least one x_5 for which x_5 is a politician, which contradicts that For all x_5, x_5 is not a politician. Therefore, the answer is no.
