Consider the following premises. For all x_6, x_6 is a sailor or x_6 will read a book. For all x_6, x_6 is not a sailor. For all x_6, if x_6 were an artist, then x_6 is working. For all x_6, if x_6 listens to a song, then x_6 is working. For all x_6, x_6 is an artist or x_6 will listen to a song. Can we infer the following from them? There is at least one x_6 for which either x_6 will read a book or x_6 will work are not true.
 From the fact that for all x_6, x_6 is a sailor or x_6 will read a book, and that for all x_6, x_6 is not a sailor we can infer that for all x_6, x_6 will read a book. From the fact that for all x_6, if x_6 were an artist, then x_6 is working, that for all x_6, if x_6 listens to a song, then x_6 is working, and that for all x_6, x_6 is an artist or x_6 will listen to a song we can infer that for all x_6, x_6 will work. Finally, from the fact that for all x_6, x_6 will read a book, and that for all x_6, x_6 will work we can infer that for all x_6, x_6 will read a book and x_6 will work, which contradicts that There is at least one x_6 for which either x_6 will read a book or x_6 will work are not true. Therefore, the answer is no.
