Consider the following premises. For all x_14, if x_14 were an office clerk, then x_14 is driving a car. Robert is not driving a car. Can we infer the following from them? Robert is an office clerk.
 From the fact that for all x_14, if x_14 were an office clerk, then x_14 is driving a car we can infer that if Robert were an office clerk, then Robert is driving a car. Finally, from the fact that if Robert were an office clerk, then Robert is driving a car, and that Robert is not driving a car we can infer that Robert is not an office clerk, which contradicts that Robert is an office clerk. Therefore, the answer is no.
