Consider the following premises. For all x_16, x_16 is not an astronaut. For all x_16, x_16 will work if and only if x_16 is sad. For all x_16, if x_16 takes a plane, then x_16 is sad. For all x_16, if x_16 works, then x_16 is an astronaut. For all x_16, if x_16 drinks water, then x_16 is taking a plane. Can we infer the following from them? For all x_16, x_16 will not drink water.
 From the fact that for all x_16, x_16 will work if and only if x_16 is sad we can infer that for all x_16, if x_16 were sad, then x_16 is working. From the fact that for all x_16, if x_16 works, then x_16 is an astronaut, and that for all x_16, x_16 is not an astronaut we can infer that for all x_16, x_16 will not work. From the fact that for all x_16, if x_16 takes a plane, then x_16 is sad, and that for all x_16, if x_16 were sad, then x_16 is working we can infer that for all x_16, if x_16 takes a plane, then x_16 is working. From the fact that for all x_16, if x_16 takes a plane, then x_16 is working, and that for all x_16, x_16 will not work we can infer that for all x_16, x_16 will not take a plane. Finally, from the fact that for all x_16, if x_16 drinks water, then x_16 is taking a plane, and that for all x_16, x_16 will not take a plane we can infer that for all x_16, x_16 will not drink water. Therefore, the answer is yes.
