Consider the following premises. For all x_6, if x_6 climbs a mountain, then x_6 is rich. There is at least one x_6 for which if x_6 climbs a mountain, then x_6 is a politician. For all x_6, if x_6 were a politician, then x_6 is climbing a mountain. 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 a politician does not imply that x_6 is rich.
That contradicts the premises. Therefore the answer is no.
