Consider the following premises. For all x, if x drinks water, then x is not fast. For all y, y is fast. Can we infer the following from them? For all x, x will drink water.
 From the fact that for all y, y is fast we can infer that Karen is fast. From the fact that Karen is fast we can infer that there is at least one x for which x is fast. Finally, from the fact that for all x, if x drinks water, then x is not fast, and that there is at least one x for which x is fast we can infer that there is at least one x for which x will not drink water, which contradicts that For all x, x will drink water. Therefore, the answer is no.
