Consider the following premises. For all x_6, x_6 will not climb a mountain. For all x_6, x_6 will climb a mountain or x_6 is a carpenter. For all x_6, x_6 will take a plane. For all x_6, if x_6 were a carpenter, then x_6 is a taxi driver. Can we infer the following from them? For all x_6, x_6 is a taxi driver and x_6 will take a plane.
 From the fact that for all x_6, x_6 will climb a mountain or x_6 is a carpenter, and that for all x_6, x_6 will not climb a mountain we can infer that for all x_6, x_6 is a carpenter. From the fact that for all x_6, if x_6 were a carpenter, then x_6 is a taxi driver, and that for all x_6, x_6 is a carpenter we can infer that for all x_6, x_6 is a taxi driver. Finally, from the fact that for all x_6, x_6 is a taxi driver, and that for all x_6, x_6 will take a plane we can infer that for all x_6, x_6 is a taxi driver and x_6 will take a plane. Therefore, the answer is yes.
