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