Input: Consider Input: 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

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


Input: Consider Input: Article: EUROPE is home to a variety of cultural treasures. Lonely Planet has offered pairs of cities for culture-hungry but time-poor travelers. London and Paris It takes you about two hours to travel from London to Paris by Eurostar, a high-speed railway service. The two capital cities have been competing in fashion, art and nightlife for decades--but each secretly looks up to the other. No one can doubt the grand and impressive beauty of Paris' Louvre Museum, but if you want to save money, you cannot skip the British Museum free to visit. Compared with London, Paris has more outdoor attractions, such as the beautiful green walkway La Promenade Plantee. In Paris, you'll see diners linger   over red wine. While in London, you can try some afternoon tea, eat fish and chips or salted cake. Vienna and Bratislava Austrian capital Vienna and Slovakia city Bratislava are an hour apart by train. But since they are linked by the Danube River, the best way to travel is by ship. A tour of the two cities is the perfect way to experience everything from 17thcentury's Habsburg dynasty splendor to sci-fi restaurants. Vienna is famous for Mozart and imperial palaces. You can appreciate the perfect blending of architecture and nature in the grand Scholoss Schonbrunn Palace, and reward yourself with a cup of Vienna coffee, which has made its way to the world's cultural heritage list. Bratislava is best known for its fine dining--the remarkable UFO restaurant. You can enjoy a meat-laden dinner here in an amazing setting. 
 Answer: They admire each other.

Output: What's the relationship between London and Paris according to the text?


Input: Consider Input: Article: Industrial pollution is not only a problem for the countries of Europe and North America but also an extremely serious problem in some developing countries. For these countries, economic growth is a very important aim. They want to introduce industries, and so they put few controls on the industries which cause pollution. Cubatao, an industrial town of 85 000 people in Brazil, is an example of the connection between industrial development and pollution. In 1954, Cubatao had no industry. Today it has more than twenty large factories, which produce many pollutants . The people of the town are suffering from the poisonous matter in their environment and the bad effects can be clearly seen. Birth shortcomings are extremely common. Among children and adults, lung problems are sometimes twelve times more common in Cubatao than in other places. It is true that Brazil, like many other countries, has laws against pollution, but these laws are not enforced strictly enough. It is cheaper for companies to take no notice of the laws and pay the fines  than to buy the expensive equipment that will reduce the pollution. It is clear, therefore, that economic growth is more important to the government than to the health of the workers. However, the responsibility  does not completely lie with the Brazilian government. The example of Cubatao shows that international companies are not acting in a responsible way either. A number of the factories in the town are owned by large companies from France, Italy, and the U. S. They are doing things in Brazil that they would not be able to do at home. If they caused the same amount of pollution at home, they would be severely  punished or even put out of business. 
 Answer: If they put stricter controls on industry, fewer companies would build new plants in developing countries.


Output: Why don't developing countries have strict pollution controls?
