Consider the following premises. For all x_8, if x_8 were a doctor, then x_8 is an electrician. For all x_8, x_8 is an artist if and only if x_8 is an electrician. For all x_8, if x_8 were a bartender, then x_8 is an electrician. For all x_8, x_8 is a bartender or x_8 is a doctor. Can we infer the following from them? There is at least one x_8 for which x_8 is not an artist.
 From the fact that for all x_8, if x_8 were a bartender, then x_8 is an electrician, that for all x_8, if x_8 were a doctor, then x_8 is an electrician, and that for all x_8, x_8 is a bartender or x_8 is a doctor we can infer that for all x_8, x_8 is an electrician. From the fact that for all x_8, x_8 is an artist if and only if x_8 is an electrician we can infer that for all x_8, if x_8 were an electrician, then x_8 is an artist. Finally, from the fact that for all x_8, if x_8 were an electrician, then x_8 is an artist, and that for all x_8, x_8 is an electrician we can infer that for all x_8, x_8 is an artist, which contradicts that There is at least one x_8 for which x_8 is not an artist. Therefore, the answer is no.
