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.

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

Example Input: Passage: Worldwide sales of hybrid vehicles produced by Toyota reached 1 million vehicles by May 31, 2007, and the 2 million mark was reached by August 2009, with hybrids sold in 50 countries. The 5 million hybrid sales milestone was reached in March 2013. During 2012, Toyota and Lexus hybrid models sold more than 1 million units a year for the first time, with 1.219 million units sold. During 2013, TMC sold 1.279 million units, and the 6 million sales milestone was achieved in December 2013, just nine months after its latest million unit milestone. The 7 million sales mark was reached in September 2014, again, selling one million hybrids in nine months, and the 8 million sales milestone was achieved in July 2015, just 10 months after the previous million-unit milestone. The 9 million sales mark was reached in April 2016, again, selling one million hybrids in just nine months, and the 10 million milestone in January 2017, one more time nine months later. Toyota estimates that up to January 31, 2017, its hybrids have saved about 7.66 billion U.S. gallons of gasoline (29 billion liters) compared to the amount used by gasoline-powered vehicles of similar size, and have emitted approximately 77 million fewer tons of CO2 emissions than would have been emitted by gasoline-powered vehicles of similar size and driving performance.
Example Output: Did it take longer to go from 6 - 7 million units sold, or from 7 - 8 million units sold?

Example Input: Passage: In week 6, the Lions traveled east to East Rutherford, New Jersey to take on the New York Giants. The Lions took an early lead midway through the first quarter with a 14-yard TD catch by Nate Burleson. The Giants responded at the end of the 1st quarter with a 4-yard TD run by Brandon Jacobs. In the second quarter, the Giants increased their lead with a 33-yard TD catch by Mario Manningham. The Lions responded with a 50-yard field goal just before halftime. Shaun Hill was also injured before halftime and left the game with a broken left forearm. Drew Stanton took over the QB role for the remainder of the game. The only score of the 3rd quarter was a 1-yard TD catch by Travis Beckum of the Giants. The Lions attempted a comeback when Calvin Johnson caught an 87-yard TD. The Giants responded with a 6-yard TD catch by Brandon Jacobs. The Lions ended the scoring with another 50-yard field goal. With the loss, not only did the Lions fall to 1-5 into their bye week, but it increased their road losing streak to 24, tying the NFL record that the team set from 2001-2003.
Example Output:
How many 50-yard field goals did the Lions score?
