Consider the following premises. For all x_9, if x_9 listens to a song, then x_9 is a lawyer. For all x_9, x_9 is not a nurse. For all x_9, if x_9 were a lawyer, then x_9 is poor. There is at least one x_9 for which x_9 is a nurse if and only if x_9 is poor. Can we infer the following from them? For all x_9, x_9 will listen to a song.
 From the fact that for all x_9, if x_9 listens to a song, then x_9 is a lawyer, and that for all x_9, if x_9 were a lawyer, then x_9 is poor we can infer that for all x_9, if x_9 listens to a song, then x_9 is poor. From the fact that there is at least one x_9 for which x_9 is a nurse if and only if x_9 is poor, and that for all x_9, x_9 is not a nurse we can infer that there is at least one x_9 for which x_9 is not poor. Finally, from the fact that for all x_9, if x_9 listens to a song, then x_9 is poor, and that there is at least one x_9 for which x_9 is not poor we can infer that there is at least one x_9 for which x_9 will not listen to a song, which contradicts that For all x_9, x_9 will listen to a song. Therefore, the answer is no.
