Consider the following premises. For all z, if z takes a plane, then z is drinking water. For all z, if z were curious, then z is taking a plane. There is at least one z for which z will drink water if and only if z is a sailor. Can we infer the following from them? If we can, name the inference rule being used: For all z, the fact that z were curious does not imply that z is a sailor.
That contradicts the premises. Therefore the answer is no.
