Consider the following premises. For all x_13, x_13 is a bartender or x_13 will sleep. For all x_5, if x_5 were poor, then x_5 is driving a car. For all x_13, x_13 will sleep if and only if x_13 is poor. For all x_13, if x_13 were a bartender, then x_13 is poor. Can we infer the following from them? Linda is driving a car.
 From the fact that for all x_13, x_13 will sleep if and only if x_13 is poor we can infer that for all x_13, if x_13 sleeps, then x_13 is poor. From the fact that for all x_13, if x_13 were a bartender, then x_13 is poor, that for all x_13, if x_13 sleeps, then x_13 is poor, and that for all x_13, x_13 is a bartender or x_13 will sleep we can infer that for all x_13, x_13 is poor. From the fact that for all x_13, x_13 is poor we can infer that Linda is poor. From the fact that for all x_5, if x_5 were poor, then x_5 is driving a car we can infer that if Linda were poor, then Linda is driving a car. Finally, from the fact that if Linda were poor, then Linda is driving a car, and that Linda is poor we can infer that Linda is driving a car. Therefore, the answer is yes.
