Consider the following premises. For all z_2, z_2 will not climb a mountain. There is at least one z_2 for which if z_2 reads a book, then z_2 is listening to a song. For all z_2, z_2 will read a book if and only if z_2 will listen to a song. For all z_2, z_2 will listen to a song if and only if z_2 will climb a mountain. Can we infer the following from them? For all z_2, z_2 will read a book.
 From the fact that for all z_2, z_2 will listen to a song if and only if z_2 will climb a mountain, and that for all z_2, z_2 will not climb a mountain we can infer that for all z_2, z_2 will not listen to a song. From the fact that for all z_2, z_2 will read a book if and only if z_2 will listen to a song we can infer that for all z_2, if z_2 listens to a song, then z_2 is reading a book. From the fact that for all z_2, if z_2 listens to a song, then z_2 is reading a book, and that there is at least one z_2 for which if z_2 reads a book, then z_2 is listening to a song we can infer that there is at least one z_2 for which z_2 will listen to a song if and only if z_2 will read a book. Finally, from the fact that there is at least one z_2 for which z_2 will listen to a song if and only if z_2 will read a book, and that for all z_2, z_2 will not listen to a song we can infer that there is at least one z_2 for which z_2 will not read a book, which contradicts that For all z_2, z_2 will read a book. Therefore, the answer is no.
