Consider the following premises. Jennifer is drinking water or it is cloudy. Jennifer is not taking a plane. For all y, y will drink water if and only if y will take a plane. Can we infer the following from them? It is not cloudy.
 From the fact that for all y, y will drink water if and only if y will take a plane we can infer that Jennifer is drinking water if and only if Jennifer is taking a plane. From the fact that Jennifer is drinking water if and only if Jennifer is taking a plane, and that Jennifer is not taking a plane we can infer that Jennifer is not drinking water. Finally, from the fact that Jennifer is drinking water or it is cloudy, and that Jennifer is not drinking water we can infer that it is cloudy, which contradicts that It is not cloudy. Therefore, the answer is no.
