Consider the following premises. For all x_11, x_11 is a scientist or x_11 is not a soldier. For all x_11, x_11 will climb a mountain or x_11 will play squash. For all x_11, if x_11 plays squash, then x_11 is a poet. For all x_11, if x_11 climbs a mountain, then x_11 is a poet. For all x_11, if x_11 reads a book, then x_11 is a scientist. For all x_11, x_11 is a soldier or x_11 will read a book. Can we infer the following from them? For all x_11, x_11 is a scientist.
 From the fact that for all x_11, x_11 is a scientist or x_11 is not a soldier we can infer that for all x_11, if x_11 were a soldier, then x_11 is a scientist. From the fact that for all x_11, if x_11 climbs a mountain, then x_11 is a poet, that for all x_11, if x_11 plays squash, then x_11 is a poet, and that for all x_11, x_11 will climb a mountain or x_11 will play squash we can infer that for all x_11, x_11 is a poet. Finally, from the fact that for all x_11, if x_11 were a soldier, then x_11 is a scientist, that for all x_11, if x_11 reads a book, then x_11 is a scientist, and that for all x_11, x_11 is a soldier or x_11 will read a book we can infer that for all x_11, x_11 is a scientist. Therefore, the answer is yes.
