Consider the following premises. For all x_5, x_5 is an artist or x_5 will not drive a car. For all x_5, if x_5 were a janitor, then x_5 is a bartender. For all x_5, if x_5 were a bartender, then x_5 is driving a car. Can we infer the following from them? There is at least one x_5 for which the fact that x_5 were a janitor does not imply that x_5 is an artist.
 From the fact that for all x_5, if x_5 were a janitor, then x_5 is a bartender, and that for all x_5, if x_5 were a bartender, then x_5 is driving a car we can infer that for all x_5, if x_5 were a janitor, then x_5 is driving a car. From the fact that for all x_5, x_5 is an artist or x_5 will not drive a car we can infer that for all x_5, if x_5 drives a car, then x_5 is an artist. Finally, from the fact that for all x_5, if x_5 were a janitor, then x_5 is driving a car, and that for all x_5, if x_5 drives a car, then x_5 is an artist we can infer that for all x_5, if x_5 were a janitor, then x_5 is an artist, which contradicts that There is at least one x_5 for which the fact that x_5 were a janitor does not imply that x_5 is an artist. Therefore, the answer is no.
