Problem: Since the end of World War II, in part due to industrial size and the onset of the Cold War, the United States has often been a proponent of reduced tariff-barriers and free trade. The U.S. helped establish the General Agreement on Tariffs and Trade and later the World Trade Organization ; although it had rejected an earlier version in the 1950s . Since the 1970s, U.S. governments have negotiated managed-trade agreements, such as the North American Free Trade Agreement in the 1990s, the Dominican Republic-Central America Free Trade Agreement in 2006, and a number of bilateral agreements . In Europe, six countries formed the European Coal and Steel Community in 1951 which became the European Economic Community in 1958. Two core objectives of the EEC were the development of a common market, subsequently renamed the single market, and establishing a customs union between its member states. After expanding its membership, the EEC became the European Union in 1993. The European Union, now the world's largest single market, has concluded free trade agreements with many countries around the world.

Problem: A large share of the UNs expenditure addresses its core mission of peace and security, and this budget is assessed separately from the main organizational budget. The peacekeeping budget for the 2015-16 fiscal year was $8.27 billion, supporting 82,318 troops deployed in 15 missions around the world. UN peace operations are funded by assessments, using a formula derived from the regular funding scale that includes a weighted surcharge for the five permanent Security Council members, who must approve all peacekeeping operations. This surcharge serves to offset discounted peacekeeping assessment rates for less developed countries. In 2017, the top 8 providers of assessed financial contributions to Peacekeeping operations were the United States (28.47%), China (10.25%), Japan (9.68%), Germany (6.39%), France (6.28%), United Kingdom (5.77%), Russian Federation (3.99%) and Italy (3.75%).
Answer this question based on the article: Which of the top 8 financial providers contribute less than 4%?
A: Russian Federation

Problem: A 1991 estimate for the global board game market was over $1.2 billion. A 2001 estimate for the United States "board games and puzzle" market gave a value of under $400 million, and for United Kingdom, of about 50 million. A 2009 estimate for the Korean market was put at 800 million won, and another estimate for the American board game market for the same year was at about $800 million. A 2011 estimate for the Chinese board game market was at over 10 billion yuan (currency). (Some estimates may split board games from Collectible card game, miniature and role-playing games; for example another 2014 estimate distinguishing board games from other types of hobby games gave the estimate for the U.S. and Canada market at only $75 million, with the total size of what it defined as the hobby game market at over $700 million, with a 2015 estimate suggesting a value of almost $900 million) A 2013 estimate put the size of the German toy market at 2.7 billion euros (out of which, the board games and puzzle market is worth about 375 million euros), and Polish markets, at 2 billion and 280 million zoty, respectively. Per capita, in 2009 Germany was considered to be the best market, with the highest number of games sold per individual.
