Consider the following premises. For all x_11, x_11 will take a plane. For all x_11, if x_11 cooks, then x_11 is a writer. There is at least one x_11 for which if x_11 sleeps, then x_11 is a writer. For all x_11, x_11 will drive a car or x_11 will cook. For all x_11, x_11 will not drive a car or x_11 will sleep. Can we infer the following from them? Some writers will take a plane.
 From the fact that for all x_11, x_11 will drive a car or x_11 will cook, and that for all x_11, x_11 will not drive a car or x_11 will sleep we can infer that for all x_11, x_11 will cook or x_11 will sleep. From the fact that for all x_11, if x_11 cooks, then x_11 is a writer, that there is at least one x_11 for which if x_11 sleeps, then x_11 is a writer, and that for all x_11, x_11 will cook or x_11 will sleep we can infer that there is at least one x_11 for which x_11 is a writer. Finally, from the fact that there is at least one x_11 for which x_11 is a writer, and that for all x_11, x_11 will take a plane we can infer that some writers will take a plane. Therefore, the answer is yes.
