Consider the following premises. For all x_8, x_8 will not take a plane. For all x_8, x_8 will not write a letter. For all x_8, x_8 will read a book or x_8 will write a letter. For all x_8, x_8 will not read a book or x_8 will take a plane. Can we infer the following from them? For all x_8, x_8 will go running.
 From the fact that for all x_8, x_8 will read a book or x_8 will write a letter, and that for all x_8, x_8 will not read a book or x_8 will take a plane we can infer that for all x_8, x_8 will write a letter or x_8 will take a plane. From the fact that for all x_8, x_8 will write a letter or x_8 will take a plane, and that for all x_8, x_8 will not write a letter we can infer that for all x_8, x_8 will take a plane. From the fact that for all x_8, x_8 will take a plane we can infer that for all x_8, x_8 will take a plane or x_8 will go running. Finally, from the fact that for all x_8, x_8 will take a plane or x_8 will go running, and that for all x_8, x_8 will not take a plane we can infer that for all x_8, x_8 will go running. Therefore, the answer is yes. Notice, however, that the premises were contradictory, so we can infer anything from them.
