If there is attention mechanism then maybe that is what is fault, because if it is a common riddle attention mechanism only notices that it is a common riddle, not that there is a gotcha planted in. Because when I read the sentence myself, I did not immediately notice that the cat that was put in there was actually dead when it was put there, because I pattern matched this to a known problem, I did not think I need to pay logical attention to each word, word by word.
