Consider the following premises. For all x_16, x_16 is a poet or x_16 will read a book. For all x_16, x_16 will play a game. There is at least one x_16 for which x_16 is not a poet. For all x_16, x_16 will climb a mountain. Can we infer the following from them? There is at least one x_16 for which x_16 will read a book and x_16 will climb a mountain.
 From the fact that for all x_16, x_16 is a poet or x_16 will read a book, and that there is at least one x_16 for which x_16 is not a poet we can infer that there is at least one x_16 for which x_16 will read a book. From the fact that there is at least one x_16 for which x_16 will read a book, and that for all x_16, x_16 will play a game we can infer that there is at least one x_16 for which x_16 will read a book and x_16 will play a game. From the fact that there is at least one x_16 for which x_16 will read a book and x_16 will play a game we can infer that there is at least one x_16 for which x_16 will read a book. Finally, from the fact that there is at least one x_16 for which x_16 will read a book, and that for all x_16, x_16 will climb a mountain we can infer that there is at least one x_16 for which x_16 will read a book and x_16 will climb a mountain. Therefore, the answer is yes.
