Consider the following premises. For all x_10, x_10 will not make tea. For all x_10, if x_10 reads a book, then x_10 is listening to a song. For all x_10, if x_10 makes tea, then x_10 is reading a book. For all x_10, if x_10 were a musician, then x_10 is listening to a song. For all x_10, if x_10 listens to a song, then x_10 is reading a book. For all x_10, if x_10 reads a book, then x_10 is making tea. Can we infer the following from them? There is at least one x_10 for which x_10 is a musician.
 From the fact that for all x_10, if x_10 makes tea, then x_10 is reading a book, and that for all x_10, if x_10 reads a book, then x_10 is making tea we can infer that for all x_10, x_10 will make tea if and only if x_10 will read a book. From the fact that for all x_10, x_10 will make tea if and only if x_10 will read a book, and that for all x_10, x_10 will not make tea we can infer that for all x_10, x_10 will not read a book. From the fact that for all x_10, if x_10 listens to a song, then x_10 is reading a book, and that for all x_10, if x_10 reads a book, then x_10 is listening to a song we can infer that for all x_10, x_10 will listen to a song if and only if x_10 will read a book. From the fact that for all x_10, x_10 will listen to a song if and only if x_10 will read a book, and that for all x_10, x_10 will not read a book we can infer that for all x_10, x_10 will not listen to a song. Finally, from the fact that for all x_10, if x_10 were a musician, then x_10 is listening to a song, and that for all x_10, x_10 will not listen to a song we can infer that for all x_10, x_10 is not a musician, which contradicts that There is at least one x_10 for which x_10 is a musician. Therefore, the answer is no.
