Consider the following premises. For all x_23, if x_23 listens to a song, then x_23 is a scientist. Susan is listening to a song or Karen is a carpenter. If Karen were a carpenter, then Susan is a scientist. If Charles were rich, then Susan is not a scientist. Can we infer the following from them? Charles is rich.
 From the fact that for all x_23, if x_23 listens to a song, then x_23 is a scientist we can infer that if Susan listens to a song, then Susan is a scientist. From the fact that if Susan listens to a song, then Susan is a scientist, that if Karen were a carpenter, then Susan is a scientist, and that Susan is listening to a song or Karen is a carpenter we can infer that Susan is a scientist. Finally, from the fact that if Charles were rich, then Susan is not a scientist, and that Susan is a scientist we can infer that Charles is not rich, which contradicts that Charles is rich. Therefore, the answer is no.
