Consider the following premises. For all x_11, if x_11 were poor, then x_11 is not a mechanic. For all x_11, x_11 is poor or x_11 is a politician. For all x_11, if x_11 were excited, then x_11 is a mechanic. There is at least one x_11 for which x_11 is excited. Can we infer the following from them? For all x_11, x_11 is not a politician.
 From the fact that for all x_11, if x_11 were excited, then x_11 is a mechanic, and that there is at least one x_11 for which x_11 is excited we can infer that there is at least one x_11 for which x_11 is a mechanic. From the fact that for all x_11, if x_11 were poor, then x_11 is not a mechanic, and that there is at least one x_11 for which x_11 is a mechanic we can infer that there is at least one x_11 for which x_11 is not poor. Finally, from the fact that for all x_11, x_11 is poor or x_11 is a politician, and that there is at least one x_11 for which x_11 is not poor we can infer that there is at least one x_11 for which x_11 is a politician, which contradicts that For all x_11, x_11 is not a politician. Therefore, the answer is no.
