Consider the following premises. For all y, y will go running if and only if y will take a plane. For all y, if y takes a plane, then y is a taxi driver. For all y, if y were a taxi driver, then y is running. Can we infer the following from them? If we can, name the inference rule being used: For all y, y will go running if and only if y will take a plane.
That is one of the premises. Therefore, the answer is yes.
