Consider the following premises. For all x_6, x_6 will read a book or x_6 is not a musician. For all x_6, if x_6 listens to a song, then x_6 is a musician. For all x_6, x_6 will not read a book. Can we infer the following from them? There is at least one x_6 for which x_6 will listen to a song.
 From the fact that for all x_6, x_6 will read a book or x_6 is not a musician we can infer that for all x_6, if x_6 were a musician, then x_6 is reading a book. From the fact that for all x_6, if x_6 were a musician, then x_6 is reading a book, and that for all x_6, x_6 will not read a book we can infer that for all x_6, x_6 is not a musician. Finally, from the fact that for all x_6, if x_6 listens to a song, then x_6 is a musician, and that for all x_6, x_6 is not a musician we can infer that for all x_6, x_6 will not listen to a song, which contradicts that There is at least one x_6 for which x_6 will listen to a song. Therefore, the answer is no.
