Consider the following premises. For all x_10, x_10 will not drink water. For all x_10, if x_10 works, then x_10 is drinking water. For all x_10, x_10 will drink water if and only if x_10 will work. For all x_10, if x_10 drinks water, then x_10 is working. Can we infer the following from them? For all x_10, x_10 will not work.
 From the fact that for all x_10, if x_10 drinks water, then x_10 is working, and that for all x_10, if x_10 works, then x_10 is drinking water we can infer that for all x_10, x_10 will drink water if and only if x_10 will work. From the fact that for all x_10, x_10 will drink water if and only if x_10 will work we can infer that for all x_10, if x_10 drinks water, then x_10 is working. From the fact that for all x_10, x_10 will drink water if and only if x_10 will work we can infer that for all x_10, if x_10 works, then x_10 is drinking water. From the fact that for all x_10, if x_10 drinks water, then x_10 is working, and that for all x_10, if x_10 works, then x_10 is drinking water we can infer that for all x_10, x_10 will drink water if and only if x_10 will work. Finally, from the fact that for all x_10, x_10 will drink water if and only if x_10 will work, and that for all x_10, x_10 will not drink water we can infer that for all x_10, x_10 will not work. Therefore, the answer is yes.
