Consider the following premises. For all x, x will drink water. For all x, x will take a plane. There is at least one x for which x is a nurse. Can we infer the following from them? For all x, either x will drink water or x will take a plane are not true.
 From the fact that for all x, x will take a plane, and that there is at least one x for which x is a nurse we can infer that there is at least one x for which x will take a plane and x is a nurse. From the fact that there is at least one x for which x will take a plane and x is a nurse we can infer that there is at least one x for which x will take a plane. Finally, from the fact that for all x, x will drink water, and that there is at least one x for which x will take a plane we can infer that there is at least one x for which x will drink water and x will take a plane, which contradicts that For all x, either x will drink water or x will take a plane are not true. Therefore, the answer is no.
