Input: Consider Input: Passage: Contrary to popular belief, Genghis Khan did not conquer all the areas ultimately part of the Mongol Empire. At the time of his death, the Mongol Empire stretched from the Caspian Sea to the Sea of Japan. The empire's expansion continued for a generation or more after Genghis's death in 1227. Under Genghis's successor Ögedei Khan the speed of expansion reached its peak. Mongol armies pushed into Persia, finished off the Western Xia and the remnants of the Khwarezmids, and came into conflict with the imperial Song dynasty of China, starting a war that lasted until 1279 and that concluded with the Mongols gaining control of all of China. They also pushed further into Russia and eastern Europe. Question: Who led the most rapid expansion of the Mongol Empire?

Output: Ögedei Khan


Input: Consider Input: Passage: The Musical Instruments gallery closed 25 February 2010, a decision which was highly controversial. An online petition of over 5,100 names on the Parliamentary website led to Chris Smith asking Parliament about the future of the collection. The answer, from Bryan Davies was that the museum intended to preserve and care for the collection and keep it available to the public, with items being redistributed to the British Galleries, the Medieval & Renaissance Galleries, and the planned new galleries for Furniture and Europe 1600–1800, and that the Horniman Museum and other institutions were possible candidates for loans of material to ensure that the instruments remained publicly viewable. The Horniman went on to host a joint exhibition with the V&A of musical instruments, and has the loan of 35 instruments from the museum. Question: Which Member of Parliament explained how the museum would preserve the collection and keep it available to the public?

Output: Bryan Davies


Input: Consider Input: Passage: The principal Treaties that form the European Union began with common rules for coal and steel, and then atomic energy, but more complete and formal institutions were established through the Treaty of Rome 1957 and the Maastricht Treaty 1992 (now: TFEU). Minor amendments were made during the 1960s and 1970s. Major amending treaties were signed to complete the development of a single, internal market in the Single European Act 1986, to further the development of a more social Europe in the Treaty of Amsterdam 1997, and to make minor amendments to the relative power of member states in the EU institutions in the Treaty of Nice 2001 and the Treaty of Lisbon 2007. Since its establishment, more member states have joined through a series of accession treaties, from the UK, Ireland, Denmark and Norway in 1972 (though Norway did not end up joining), Greece in 1979, Spain and Portugal 1985, Austria, Finland, Norway and Sweden in 1994 (though again Norway failed to join, because of lack of support in the referendum), the Czech Republic, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia in 2004, Romania and Bulgaria in 2007 and Croatia in 2013. Greenland signed a Treaty in 1985 giving it a special status. Question: When did Greenland sign a Treaty granting them special status?
Output: 1985
