Consider the following premises. For all y_2, y_2 is bored if and only if y_2 will read a book. For all y_2, y_2 is a poet if and only if y_2 is bored. There is at least one y_2 for which y_2 is not a poet. Can we infer the following from them? For all y_2, y_2 will read a book.
 From the fact that for all y_2, y_2 is a poet if and only if y_2 is bored we can infer that for all y_2, if y_2 were bored, then y_2 is a poet. From the fact that for all y_2, if y_2 were bored, then y_2 is a poet, and that there is at least one y_2 for which y_2 is not a poet we can infer that there is at least one y_2 for which y_2 is not bored. Finally, from the fact that for all y_2, y_2 is bored if and only if y_2 will read a book, and that there is at least one y_2 for which y_2 is not bored we can infer that there is at least one y_2 for which y_2 will not read a book, which contradicts that For all y_2, y_2 will read a book. Therefore, the answer is no.
