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