Consider the following premises. For all x_8, if x_8 were a cashier, then x_8 is an artist. For all x_8, if x_8 listens to a song, then x_8 is a bartender. John is not a bartender. For all x_8, if x_8 were an artist, then x_8 is listening to a song. For all x_8, if x_8 were a bartender, then x_8 is a cashier. Can we infer the following from them? John is not an artist.
 From the fact that for all x_8, if x_8 were an artist, then x_8 is listening to a song, and that for all x_8, if x_8 listens to a song, then x_8 is a bartender we can infer that for all x_8, if x_8 were an artist, then x_8 is a bartender. From the fact that for all x_8, if x_8 were a bartender, then x_8 is a cashier, and that for all x_8, if x_8 were a cashier, then x_8 is an artist we can infer that for all x_8, if x_8 were a bartender, then x_8 is an artist. From the fact that for all x_8, if x_8 were an artist, then x_8 is a bartender, and that for all x_8, if x_8 were a bartender, then x_8 is an artist we can infer that for all x_8, x_8 is an artist if and only if x_8 is a bartender. From the fact that for all x_8, x_8 is an artist if and only if x_8 is a bartender we can infer that John is an artist if and only if John is a bartender.
