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: Spanish Town is the site of an early cast-iron bridge, designed by Thomas Wilson and manufactured by Walker and Company of Rotherham, England. Spanning the Rio Cobre, the bridge was erected in 1801 at a cost of £4,000. Its four arched ribs are supported on massive masonry abutments. After the abutments deteriorated, endangering the structure, it was listed in the 1998 World Monuments Watch by the World Monuments Fund. A restoration project began in 2004, with funding provided by American Express through World Monuments Fund. Progress was slow until 2008, when a renewed restoration effort was made. A first phase of restoration was completed in April 2010, when the repair of the abutments allowed the bridge to be reopened for the public. More recently, violence in the area has prevented the bridge from achieving the status of a UNESCO World Heritage Site.

Output: How many years after being built was it before the bridge restoration began?


Input: Consider Input: Passage: At Pagan, the new king Kyawswa controlled just a small area outside the capital. Instead, the real power rested with three former Pagan commanders of nearby Myinsaing. It was the brothers, not the nominal sovereign Kyawswa, that sent a force to retake Lower Burma in 1294 after Wareru had decided to become a vassal of the Sukhothai Kingdom. Wareru drove back the Myinsaing forces. Concerned by the increasing power of the three brothers, Kyawswa submitted to the Mongols in January 1297, and was recognised by the Mongol emperor Temür Khan as viceroy of Pagan on 20 March 1297. In December 1297, the three brothers overthrew Kyawswa, and founded the Myinsaing Kingdom. In January 1300, the Myinsaing forces led by Athinhkaya seized the southernmost Mongol garrisons named Nga Singu and Male, just north of modern Mandalay. On 22 June 1300, the Mongol Emperor declared that Kumara Kassapa, one of Kyawswa's sons, was the rightful king of Burma, and sent in a 12,000-strong army from Yunnan. The Mongol army reached Male on 15 January 1301, and Myinsaing on 25 January. But they could not break through. The besiegers took the bribes given by the three brothers, and began their retreat on 6 April. But the commanders were executed by the Yunnan government when they got back. The Mongols sent no more invasions, and withdrew entirely from Upper Burma on 4 April 1303.

Output: How many days did it take the Mongol armey to travel from Male to Myinsaing?


Input: Consider Input: Passage: The 10th Cavalry returned from the Philippines in late 1902 and settled down in different posts in the south western United States. Patrols and garrison life was the routine for the regiment. Under war plans, the 10th was designated for service in the Pacific and support in the Philippines from 1915 through 1942 but never rotated there. The 9th Cavalry Regiment  became "Park Rangers" in 1905 for Yosemite National Park and other state and federal lands. The Troopers' Campaign Hat, sporting the "Montana Pinch" used to help shed the tropical downpours. That "Montana Pinch" gave the hat the distinctive look we recognize today as the "Smokey Bear Hat".


Output: How many Calvary's are mentioned?
