Consider the following premises. If Jessica drives a car, then Linda is an artist. Linda is not playing squash. For all x_12, if x_12 plays squash, then x_12 is an artist. If Linda were an artist, then Linda is playing squash. Can we infer the following from them? If we can, name the inference rule being used: Jessica is driving a car.
 From the fact that for all x_12, if x_12 plays squash, then x_12 is an artist we can infer that if Linda plays squash, then Linda is an artist via universal instantiation. From the fact that if Linda plays squash, then Linda is an artist, and that if Linda were an artist, then Linda is playing squash we can infer that Linda is playing squash if and only if Linda is an artist via biconditional introduction. From the fact that Linda is playing squash if and only if Linda is an artist, and that Linda is not playing squash we can infer that Linda is not an artist via biconditional elimination. Finally, from the fact that if Jessica drives a car, then Linda is an artist, and that Linda is not an artist we can infer that Jessica is not driving a car via modus tollens, which contradicts that Jessica is driving a car. Therefore, the answer is no.
