Consider the following premises. For all x_6, if x_6 drives a car, then x_6 is rich. For all x_6, if x_6 works, then x_6 is a bartender. For all x_6, x_6 will work or x_6 will drive a car. For all x_6, x_6 is rich or x_6 is not a bartender. Can we infer the following from them? There is at least one x_6 for which x_6 is not rich.
 From the fact that for all x_6, x_6 is rich or x_6 is not a bartender we can infer that for all x_6, if x_6 were a bartender, then x_6 is rich. From the fact that for all x_6, if x_6 works, then x_6 is a bartender, and that for all x_6, if x_6 were a bartender, then x_6 is rich we can infer that for all x_6, if x_6 works, then x_6 is rich. Finally, from the fact that for all x_6, if x_6 works, then x_6 is rich, that for all x_6, if x_6 drives a car, then x_6 is rich, and that for all x_6, x_6 will work or x_6 will drive a car we can infer that for all x_6, x_6 is rich, which contradicts that There is at least one x_6 for which x_6 is not rich. Therefore, the answer is no.
