Consider the following premises. For all x_10, x_10 will take a plane or x_10 is a taxi driver. For all x_10, x_10 is a mechanic or x_10 will not cook. For all x_10, x_10 is not a mechanic. For all x_10, x_10 will cook if and only if x_10 will take a plane. Can we infer the following from them? For all x_10, x_10 is a taxi driver.
 From the fact that for all x_10, x_10 is a mechanic or x_10 will not cook we can infer that for all x_10, if x_10 cooks, then x_10 is a mechanic. From the fact that for all x_10, if x_10 cooks, then x_10 is a mechanic, and that for all x_10, x_10 is not a mechanic we can infer that for all x_10, x_10 will not cook. From the fact that for all x_10, x_10 will cook if and only if x_10 will take a plane, and that for all x_10, x_10 will not cook we can infer that for all x_10, x_10 will not take a plane. Finally, from the fact that for all x_10, x_10 will take a plane or x_10 is a taxi driver, and that for all x_10, x_10 will not take a plane we can infer that for all x_10, x_10 is a taxi driver. Therefore, the answer is yes.
