Consider the following premises. Thomas is not a police officer. If James were not a soldier, then Jennifer is driving a car. If Jennifer drives a car, then Richard is a bartender. If James were a soldier, then Thomas is a police officer. Can we infer the following from them? Richard is not a bartender.
 From the fact that if James were a soldier, then Thomas is a police officer, and that Thomas is not a police officer we can infer that James is not a soldier. From the fact that if James were not a soldier, then Jennifer is driving a car, and that James is not a soldier we can infer that Jennifer is driving a car. Finally, from the fact that if Jennifer drives a car, then Richard is a bartender, and that Jennifer is driving a car we can infer that Richard is a bartender, which contradicts that Richard is not a bartender. Therefore, the answer is no.
