Consider the following premises. For all x_12, if x_12 plays a game, then x_12 is a sailor. There is at least one x_12 for which x_12 will cook or x_12 will drink water. For all x_12, x_12 will play a game. For all x_12, x_12 will not cook. Can we infer the following from them? If we can, name the inference rule being used: For all x_12, x_12 is not a sailor.
That contradicts the premises. Therefore the answer is no.
