Consider the following premises. For all x_8, x_8 is a server if and only if x_8 will drive a car. Jennifer is rich if and only if Patricia is driving a car. For all x_8, x_8 is not a server. Can we infer the following from them? Jennifer is not rich.
 From the fact that for all x_8, x_8 is a server if and only if x_8 will drive a car, and that for all x_8, x_8 is not a server we can infer that for all x_8, x_8 will not drive a car. From the fact that for all x_8, x_8 will not drive a car we can infer that Patricia is not driving a car. Finally, from the fact that Jennifer is rich if and only if Patricia is driving a car, and that Patricia is not driving a car we can infer that Jennifer is not rich. Therefore, the answer is yes.
