Consider the following premises. There is at least one x_19 for which x_19 will read a book if and only if x_19 will listen to a song. For all x_19, x_19 will cook if and only if x_19 will read a book. For all x_19, x_19 will not listen to a song. For all x_19, x_19 will cook if and only if x_19 will make tea. Can we infer the following from them? There is at least one x_19 for which x_19 will not make tea.
 From the fact that there is at least one x_19 for which x_19 will read a book if and only if x_19 will listen to a song, and that for all x_19, x_19 will not listen to a song we can infer that there is at least one x_19 for which x_19 will not read a book. From the fact that for all x_19, x_19 will cook if and only if x_19 will read a book we can infer that for all x_19, if x_19 cooks, then x_19 is reading a book. From the fact that for all x_19, if x_19 cooks, then x_19 is reading a book, and that there is at least one x_19 for which x_19 will not read a book we can infer that there is at least one x_19 for which x_19 will not cook. Finally, from the fact that for all x_19, x_19 will cook if and only if x_19 will make tea, and that there is at least one x_19 for which x_19 will not cook we can infer that there is at least one x_19 for which x_19 will not make tea. Therefore, the answer is yes.
