Consider the following premises. For all x_20, x_20 is a writer or x_20 will play a game. For all x_20, x_20 will take a plane or x_20 will not play a game. There is at least one x_20 for which if x_20 takes a plane, then x_20 is a taxi driver. For all x_20, x_20 is not a writer. Can we infer the following from them? If we can, name the inference rule being used: For all x_20, neither x_20 is a taxi driver nor x_20 will play squash.
That contradicts the premises. Therefore the answer is no.
