Consider the following premises. For all x_2, x_2 will read a book or x_2 is not an office clerk. For all x_2, x_2 is a taxi driver or x_2 is an office clerk. There is at least one x_2 for which if x_2 were a taxi driver, then x_2 is reading a book. Can we infer the following from them? There is at least one x_2 for which x_2 will read a book.
 From the fact that for all x_2, x_2 will read a book or x_2 is not an office clerk we can infer that for all x_2, if x_2 were an office clerk, then x_2 is reading a book. Finally, from the fact that there is at least one x_2 for which if x_2 were a taxi driver, then x_2 is reading a book, that for all x_2, if x_2 were an office clerk, then x_2 is reading a book, and that for all x_2, x_2 is a taxi driver or x_2 is an office clerk we can infer that there is at least one x_2 for which x_2 will read a book. Therefore, the answer is yes.
