Consider the following premises. If Linda climbs a mountain, then Jessica is a scientist. Richard is not taking a plane. If Jessica were a scientist, then Richard is taking a plane. For all x_16, x_16 will climb a mountain if and only if x_16 is a police officer. Can we infer the following from them? Linda is a police officer.
 From the fact that if Jessica were a scientist, then Richard is taking a plane, and that Richard is not taking a plane we can infer that Jessica is not a scientist. From the fact that for all x_16, x_16 will climb a mountain if and only if x_16 is a police officer we can infer that Linda is climbing a mountain if and only if Linda is a police officer. From the fact that if Linda climbs a mountain, then Jessica is a scientist, and that Jessica is not a scientist we can infer that Linda is not climbing a mountain. Finally, from the fact that Linda is climbing a mountain if and only if Linda is a police officer, and that Linda is not climbing a mountain we can infer that Linda is not a police officer, which contradicts that Linda is a police officer. Therefore, the answer is no.
