Consider the following premises. For all x_5, x_5 will not listen to a song or x_5 will make tea. For all x_5, if x_5 makes tea, then x_5 is a cashier. There is at least one x_5 for which x_5 will listen to a song or x_5 is fast. For all x_5, x_5 is not fast or x_5 will read a book. For all x_5, if x_5 reads a book, then x_5 is a cashier. Can we infer the following from them? There is at least one x_5 for which x_5 is a cashier.
 From the fact that there is at least one x_5 for which x_5 will listen to a song or x_5 is fast, and that for all x_5, x_5 will not listen to a song or x_5 will make tea we can infer that there is at least one x_5 for which x_5 is fast or x_5 will make tea. From the fact that there is at least one x_5 for which x_5 is fast or x_5 will make tea, and that for all x_5, x_5 is not fast or x_5 will read a book we can infer that there is at least one x_5 for which x_5 will make tea or x_5 will read a book. Finally, from the fact that for all x_5, if x_5 makes tea, then x_5 is a cashier, that for all x_5, if x_5 reads a book, then x_5 is a cashier, and that there is at least one x_5 for which x_5 will make tea or x_5 will read a book we can infer that there is at least one x_5 for which x_5 is a cashier. Therefore, the answer is yes.
