Consider the following premises. For all x_11, if x_11 were a taxi driver, then x_11 is taking a plane. For all x_11, x_11 is a writer or x_11 will work. For all x_11, if x_11 reads a book, then x_11 is a taxi driver. There is at least one x_11 for which if x_11 works, then x_11 is reading a book. For all x_11, if x_11 takes a plane, then x_11 is a writer. For all x_11, if x_11 were a writer, then x_11 is taking a plane. Can we infer the following from them? For all x_11, x_11 will not take a plane.
 From the fact that there is at least one x_11 for which if x_11 works, then x_11 is reading a book, and that for all x_11, if x_11 reads a book, then x_11 is a taxi driver we can infer that there is at least one x_11 for which if x_11 works, then x_11 is a taxi driver. From the fact that there is at least one x_11 for which if x_11 works, then x_11 is a taxi driver, and that for all x_11, if x_11 were a taxi driver, then x_11 is taking a plane we can infer that there is at least one x_11 for which if x_11 works, then x_11 is taking a plane. From the fact that for all x_11, if x_11 were a writer, then x_11 is taking a plane, and that for all x_11, if x_11 takes a plane, then x_11 is a writer we can infer that for all x_11, x_11 is a writer if and only if x_11 will take a plane. From the fact that for all x_11, x_11 is a writer if and only if x_11 will take a plane we can infer that for all x_11, if x_11 were a writer, then x_11 is taking a plane. Finally, from the fact that for all x_11, if x_11 were a writer, then x_11 is taking a plane, that there is at least one x_11 for which if x_11 works, then x_11 is taking a plane, and that for all x_11, x_11 is a writer or x_11 will work we can infer that there is at least one x_11 for which x_11 will take a plane, which contradicts that For all x_11, x_11 will not take a plane. Therefore, the answer is no.
