Consider the following premises. Some janitors will play tennis. For all x_6, x_6 will read a book. Can we infer the following from them? For all x_6, either x_6 will read a book or x_6 is a janitor are not true.
 From the fact that some janitors will play tennis we can infer that there is at least one x_6 for which x_6 is a janitor. Finally, from the fact that for all x_6, x_6 will read a book, and that there is at least one x_6 for which x_6 is a janitor we can infer that there is at least one x_6 for which x_6 will read a book and x_6 is a janitor, which contradicts that For all x_6, either x_6 will read a book or x_6 is a janitor are not true. Therefore, the answer is no.
