TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
PROBLEM: Article: A board game is a game played on a pre-marked surface or "board" according to a set of rules. Board games have been played in most cultures and societies throughout history. Do you think of yourself as a bit of an expert at board games like chess or Go? Maybe you're not quite as good as you think. New research from the University of Manchester and Oxford suggests complex games like these are impossible to learn fully. They may even be too complex for the human mind to understand. Researchers studied two-player games, to try and understand the strategies which people use to make decisions during the game. Some games with two players are simple, with only a small number of possible moves. Players can quickly work out the best strategy but that means the game soon becomes boring. It gets more interesting when there are many possible moves. That's why people are so fascinated by complex board games like chess or Go, or some card games. But what the researchers found was that with difficult games, players find it hard to work out the best strategy and their actions become less reasonable. This research is part of the field called game theory: the study of human strategic decision-making. Much thinking on how people play complex games is based on something called "the balance point", which is when players have a perfect knowledge of what they are going to do and of what their rivals are going to do. When you add more than two players then of course the game becomes even harder to understand. Trading on the stock market is an example of a complex multi-player game.
Answer: Mahjong

SOLUTION: Which of the following games belongs to board games?

PROBLEM: Article: During my many contacts with people in China, I have been asked by two different people what I would recommend to them so that they could be happy. One of these people was my student and friend who began her question by saying I always appeared happy to her. She then asked how I could be this way and if I could teach her how to be happy all the time. The other inquiry was basically the same and came from the secretary of a company for which I was doing some work. The first one to ask was my student and in thinking about an answer I even explored in class the idea of optimism and pessimism, of people who feel the glass is always half full and those who think it is half empty. It was easy to show that different people react differently to the same situations and conditions but that didn't bring me much closer to understanding why. About two months later I was riding to the airport in a taxi with the company secretary who asked me the same question and it made me think. Why did both these ladies feel they needed help to become happy? Indeed, why did either of them think they were not happy? Why did they choose to ask this question of me? Why are some people generally happy while others are not? Certainly if someone is healthy, it might be expected that they are happy, and this is probably true. However, some people have money and health but have a miserable _ that makes it difficult for them to have friends and meaningful relationships. Similarly, one would expect those who have little to complain about their fate and many do, but others are able to enjoy what they have and enjoy life. It seems the difference must lie within the people. What we may be looking at is acceptance of a personal set of circumstances and the contentment which flows from that. _ should not mean, however, that those people cannot wish for something better. If the difference between people who are happy and those who are not lies within the people themselves, can happiness be learned? I think there are things we can do, such as dreaming of the future, which can give us the sort of positive outlook which will generally make us happy people.
Answer: Those who feel the glass is always half full are pessimistic.

SOLUTION: According to the passage, which of the following is true?

PROBLEM: Article: A few minutes later she got up and went to the phone. She knew the number of the police station, and when the man at the other end answered, she cried to him. "Quick! Come quick! Patrick's dead!" "Who's speaking?" "Mrs Maloney. Mrs Patrick Maloney." "You mean Patrick Maloney's dead?" "I think so," she sobbed. "He's lying on the floor and I think he's dead." "Be right over," the man said. The car came very quickly, and when she opened the front door, two policemen walked in. She knew them both--she knew nearly all the men at that precinct. Briefly, she told her story about going out to the grocer and coming back to find him on the floor. While she was talking, crying and talking, Noonan discovered a small patch of congealed blood on the dead man's head. He showed it to O'Malley who got up at once and hurried to the phone. Later, one of the detectives came up and sat beside her. Did she know, he asked, of anything in the house that could've been used as the weapon? Would she mind having a look around to see if anything was missing--a very big spanner, for example, or a heavy metal vase. They didn't have any heavy metal vases, she said. "Or a big spanner ?" She didn't think they had a big spanner. But there might be some things like that in the garage. The search went on. She knew that there were other policemen in the garden all around the house. She could hear their footsteps on the gravel outside, and sometimes she saw the flash of a torchlight through a chink in the curtains. Then one by one they came in and were persuaded to take a little nip of whisky. They stood around rather awkwardly with the drinks in their hands, uncomfortable in her presence, trying to say consoling things to her. Sergeant Noonan wandered into the kitchen, came out quickly and said. "Look, Mrs Maloney. You know that oven of yours is still on, and the meat still inside...I better turn it off for you, hadn't I?" "Will you do that, Jack. Thank you so much." When the sergeant returned the second time, she looked at him with her large, dark, tearful eyes. "Would you do me a small favour--you and these others?" She said. "We can try, Mrs Maloney." "Well," she said. "You must be terribly hungry by now because it's long past your supper time. Why don't you eat up that lamb that's in the oven? It'll be cooked just right by now." "Wouldn't dream of it," Sergeant Noonan said. "Please," she begged. "Please eat it." The four policemen _ , but they were clearly hungry, and in the end they were persuaded to go into the kitchen and help themselves. The woman stayed where she was, listening to them through the open door, and she could hear them speaking among themselves, their voices thick and sloppy because their mouths were full of meat. "The guy must've used a big thing to hit Patrick," one of them was saying. "The doctor says his skull was smashed all to pieces." "That's why it ought to be easy to find." "Exactly what I say." "The murderer's not going to carrying a thing like that around with him longer than he needs." One of them belched. "Personally, I think it's right here on the premises." "Probably right under our very noses. What you think, Jack?" And in the other room, Mary Maloney began to giggle.
Answer: The policemen were dealing with the murder of Mary's brother.
