Consider the following premises. For all y, if y drinks water, then y is happy. For all y, if y were happy, then y is drinking water. There is at least one y for which y will drink water or y is not happy. Can we infer the following from them? If we can, name the inference rule being used: For all y, the fact that y were happy does not imply that y is drinking water.
That contradicts the premises. Therefore the answer is no.
