Consider the following premises. If Charles were a carpenter, then Sarah is listening to a song. If Sarah listens to a song, then Jennifer is an artist. Jennifer is not an artist. Can we infer the following from them? If we can, name the inference rule being used: Charles is not a carpenter.
 From the fact that if Sarah listens to a song, then Jennifer is an artist, and that Jennifer is not an artist we can infer that Sarah is not listening to a song via modus tollens. Finally, from the fact that if Charles were a carpenter, then Sarah is listening to a song, and that Sarah is not listening to a song we can infer that Charles is not a carpenter via modus tollens. Therefore, the answer is yes.
