Consider the following premises. For all x_5, if x_5 cooks, then x_5 is taking a plane. For all x_5, x_5 will take a plane if and only if x_5 will drink water. For all x_5, if x_5 were a carpenter, then x_5 is cooking. For all x_5, x_5 is a carpenter or x_5 will drink water. Can we infer the following from them? For all x_5, x_5 will take a plane.
 From the fact that for all x_5, if x_5 were a carpenter, then x_5 is cooking, and that for all x_5, if x_5 cooks, then x_5 is taking a plane we can infer that for all x_5, if x_5 were a carpenter, then x_5 is taking a plane. From the fact that for all x_5, x_5 will take a plane if and only if x_5 will drink water we can infer that for all x_5, if x_5 drinks water, then x_5 is taking a plane. Finally, from the fact that for all x_5, if x_5 were a carpenter, then x_5 is taking a plane, that for all x_5, if x_5 drinks water, then x_5 is taking a plane, and that for all x_5, x_5 is a carpenter or x_5 will drink water we can infer that for all x_5, x_5 will take a plane. Therefore, the answer is yes.
