Consider the following premises. For all x_8, if x_8 were an electrician, then x_8 is taking a plane. If John were an office clerk, then Jennifer is an electrician. For all x_8, if x_8 takes a plane, then x_8 is an electrician. Can we infer the following from them? If we can, name the inference rule being used: The fact that John were an office clerk does not imply that Jennifer is taking a plane.
That contradicts the premises. Therefore the answer is no.
