Consider the following premises. For all x_12, if x_12 were a nurse, then x_12 is a poet. There is at least one x_12 for which x_12 is a police officer. For all x_12, x_12 is a nurse. Can we infer the following from them? For all x_12, neither x_12 is a police officer nor x_12 will read a book.
 From the fact that for all x_12, if x_12 were a nurse, then x_12 is a poet, and that for all x_12, x_12 is a nurse we can infer that for all x_12, x_12 is a poet. From the fact that there is at least one x_12 for which x_12 is a police officer, and that for all x_12, x_12 is a poet we can infer that there is at least one x_12 for which x_12 is a police officer and x_12 is a poet. From the fact that there is at least one x_12 for which x_12 is a police officer and x_12 is a poet we can infer that there is at least one x_12 for which x_12 is a police officer. Finally, from the fact that there is at least one x_12 for which x_12 is a police officer we can infer that there is at least one x_12 for which x_12 is a police officer or x_12 will read a book, which contradicts that For all x_12, neither x_12 is a police officer nor x_12 will read a book. Therefore, the answer is no.
