Consider the following premises. For all x_5, x_5 is a bartender. For all x_5, if x_5 works, then x_5 is curious. For all x_5, if x_5 were a bartender, then x_5 is working. There is at least one x_5 for which x_5 is a politician. Can we infer the following from them? There is at least one x_5 for which x_5 is curious and x_5 is a politician.
 From the fact that for all x_5, if x_5 were a bartender, then x_5 is working, and that for all x_5, x_5 is a bartender we can infer that for all x_5, x_5 will work. From the fact that for all x_5, if x_5 works, then x_5 is curious, and that for all x_5, x_5 will work we can infer that for all x_5, x_5 is curious. Finally, from the fact that for all x_5, x_5 is curious, and that there is at least one x_5 for which x_5 is a politician we can infer that there is at least one x_5 for which x_5 is curious and x_5 is a politician. Therefore, the answer is yes.
