Consider the following premises. There is at least one x_11 for which x_11 will work or x_11 will read a book. For all x_11, x_11 will not work. For all x_11, x_11 is a lawyer or x_11 will not read a book. Can we infer the following from them? There is at least one x_11 for which x_11 is a lawyer.
 From the fact that for all x_11, x_11 is a lawyer or x_11 will not read a book we can infer that for all x_11, if x_11 reads a book, then x_11 is a lawyer. From the fact that there is at least one x_11 for which x_11 will work or x_11 will read a book, and that for all x_11, x_11 will not work we can infer that there is at least one x_11 for which x_11 will read a book. Finally, from the fact that for all x_11, if x_11 reads a book, then x_11 is a lawyer, and that there is at least one x_11 for which x_11 will read a book we can infer that there is at least one x_11 for which x_11 is a lawyer. Therefore, the answer is yes.
