Consider the following premises. Susan is driving a car or it is not raining. Elisabeth is taking a plane or it is raining. If Linda were a doctor, then Elisabeth is taking a plane. Linda is not a doctor. If Elisabeth takes a plane, then Linda is a doctor. Can we infer the following from them? Susan is not driving a car.
 From the fact that if Linda were a doctor, then Elisabeth is taking a plane, and that if Elisabeth takes a plane, then Linda is a doctor we can infer that Linda is a doctor if and only if Elisabeth is taking a plane. From the fact that Susan is driving a car or it is not raining we can infer that if it rains, then Susan is driving a car. From the fact that Linda is a doctor if and only if Elisabeth is taking a plane, and that Linda is not a doctor we can infer that Elisabeth is not taking a plane. From the fact that Elisabeth is taking a plane or it is raining, and that Elisabeth is not taking a plane we can infer that it is raining. Finally, from the fact that if it rains, then Susan is driving a car, and that it is raining we can infer that Susan is driving a car, which contradicts that Susan is not driving a car. Therefore, the answer is no.
