Consider the following premises. For all x_6, if x_6 were poor, then x_6 is sleeping. For all x_6, if x_6 were an electrician, then x_6 is sad. For all x_6, if x_6 were sad, then x_6 is a doctor. There is at least one x_6 for which if x_6 were a doctor, then x_6 is poor. Can we infer the following from them? If we can, name the inference rule being used: For all x_6, the fact that x_6 were an electrician does not imply that x_6 is sleeping.
That contradicts the premises. Therefore the answer is no.
