Consider the following premises. For all x_6, x_6 will drive a car or x_6 will not climb a mountain. For all x_6, x_6 will read a book if and only if x_6 will climb a mountain. Can we infer the following from them? There is at least one x_6 for which the fact that x_6 reads a book does not imply that x_6 is driving a car.
 From the fact that for all x_6, x_6 will drive a car or x_6 will not climb a mountain we can infer that for all x_6, if x_6 climbs a mountain, then x_6 is driving a car. From the fact that for all x_6, x_6 will read a book if and only if x_6 will climb a mountain we can infer that for all x_6, if x_6 reads a book, then x_6 is climbing a mountain. Finally, from the fact that for all x_6, if x_6 reads a book, then x_6 is climbing a mountain, and that for all x_6, if x_6 climbs a mountain, then x_6 is driving a car we can infer that for all x_6, if x_6 reads a book, then x_6 is driving a car, which contradicts that There is at least one x_6 for which the fact that x_6 reads a book does not imply that x_6 is driving a car. Therefore, the answer is no.
