Consider the following premises. There is at least one x_6 for which if x_6 were a musician, then x_6 is climbing a mountain. For all x_6, if x_6 climbs a mountain, then x_6 is reading a book. For all x_6, if x_6 drinks water, then x_6 is curious. For all x_6, if x_6 were curious, then x_6 is a musician. Can we infer the following from them? There is at least one x_6 for which if x_6 drinks water, then x_6 is reading a book.
 From the fact that there is at least one x_6 for which if x_6 were a musician, then x_6 is climbing a mountain, and that for all x_6, if x_6 climbs a mountain, then x_6 is reading a book we can infer that there is at least one x_6 for which 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 curious, then x_6 is a musician, and that there is at least one x_6 for which if x_6 were a musician, then x_6 is reading a book we can infer that there is at least one x_6 for which if x_6 were curious, then x_6 is reading a book. Finally, from the fact that for all x_6, if x_6 drinks water, then x_6 is curious, and that there is at least one x_6 for which if x_6 were curious, then x_6 is reading a book we can infer that there is at least one x_6 for which if x_6 drinks water, then x_6 is reading a book. Therefore, the answer is yes.
