Consider the following premises. For all x_15, if x_15 were a taxi driver, then x_15 is poor. For all x_15, x_15 is a politician or x_15 is a taxi driver. For all x_15, if x_15 plays a game, then x_15 is not poor. For all x_15, x_15 is not a politician. William is playing a game or Michael is drinking water. Can we infer the following from them? If we can, name the inference rule being used: For all x_15, x_15 is a politician or x_15 is a taxi driver.
That is one of the premises. Therefore, the answer is yes.
