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