Consider the following premises. For all x_10, if x_10 listens to a song, then x_10 is reading a book. For all x_10, x_10 is an electrician. For all x_10, if x_10 works, then x_10 is listening to a song. For all x_10, x_10 will write a letter if and only if x_10 will read a book. For all x_10, if x_10 writes a letter, then x_10 is not an electrician. For all x_10, if x_10 reads a book, then x_10 is working. Can we infer the following from them? There is at least one x_10 for which x_10 will listen to a song.
 From the fact that for all x_10, if x_10 reads a book, then x_10 is working, and that for all x_10, if x_10 works, then x_10 is listening to a song we can infer that for all x_10, if x_10 reads a book, then x_10 is listening to a song. From the fact that for all x_10, if x_10 writes a letter, then x_10 is not an electrician, and that for all x_10, x_10 is an electrician we can infer that for all x_10, x_10 will not write a letter. From the fact that for all x_10, if x_10 reads a book, then x_10 is listening to a song, and that for all x_10, if x_10 listens to a song, then x_10 is reading a book we can infer that for all x_10, x_10 will read a book if and only if x_10 will listen to a song. From the fact that for all x_10, x_10 will write a letter if and only if x_10 will read a book, and that for all x_10, x_10 will not write a letter we can infer that for all x_10, x_10 will not read a book. Finally, from the fact that for all x_10, x_10 will read a book if and only if x_10 will listen to a song, 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, which contradicts that There is at least one x_10 for which x_10 will listen to a song. Therefore, the answer is no.
