This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Input: Consider Input: Passage: For the last time Fairfax's appearance in arms helped to shape the future of the country, when George Monck invited him to assist in the operations about to be undertaken against John Lambert's army. In December 1659 he appeared at the head of a body of Yorkshire gentlemen, and such was the influence of Fairfax's name and reputation that 1,200 horse quit Lambert's colours and joined him. This was speedily followed by the breaking up of all Lambert's forces, and that day secured the restoration of the monarchy. For these actions, along with his honourable conduct in the civil war, he was spared from the wave of Royalist retributions. In April 1660 Fairfax was re-elected MP for Yorkshire in the Convention Parliament. He was put at the head of the commission appointed by the House of Commons to wait upon Charles II, at the Hague and urge his speedy return.

Input: Consider Input: Passage: The Tolui family successfully enthroned their candidate for Great Khan, Möngke, in the kurultais of 1250 and 1251.  The Ögedeid candidate for Great Khan, Shiremun, and his cousin Nakhu, were embittered by their loss and plotted a failed assassination of Möngke.  Möngke took revenge by purging his opponents in the royal house, and members of both the Chagatai and Ögedei families. Möngke handed control over the Caucasus region to the Golden Horde in 1252.  With the approval of Möngke, Berke succeeded his brother, Batu, as Khan of the Golden Horde in Russia in 1255.  Hulagu of the Ilkhanate seized control of the Caucasus from the Golden Horde, and his sacking of Baghdad  in 1258 angered Berke, a convert to Islam.  Möngke Khan died in 1259 without appointing a successor. He likely favored Ariq Böke, whom Möngke designated in 1258 as commander of Karakorum , but he did little else to secure Ariq Böke's claim to the throne.


Output: After becoming the Great Khan in 1250, how many years was it until Mongke died?
