Consider the following premises. For all x_14, x_14 will work if and only if x_14 will sleep. There is at least one x_14 for which x_14 will work or x_14 is not a politician. For all x_14, if x_14 sleeps, then x_14 is a politician. Can we infer the following from them? If we can, name the inference rule being used: For all x_14, the fact that x_14 were a politician does not imply that x_14 is working.
That contradicts the premises. Therefore the answer is no.
