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.

[EX Q]: 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.
[EX A]: How many days did it take the Mongol armey to travel from Male to Myinsaing?

[EX Q]: Passage: Hoping to rebound from their embarrassing road loss to the Steelers, the Seahawks went home for Sunday Night football, as they hosted the winless New Orleans Saints.  In the first quarter, Seattle trailed early as a blocked punt would result in New Orleans RB Pierre Thomas returning the loose ball 5 yards for a touchdown, along with the only score of the period.  In the second quarter, the 'Hawks continued to trail as Saints QB Drew Brees completed a 3-yard TD pass to TE Eric Johnson, while WR Lance Moore got a 7-yard TD run.  The Seahawks would respond with QB Matt Hasselbeck completing a 17-yard TD pass to WR Ben Obomanu.  However, New Orleans went back to work with Brees completing a 2-yard TD pass to WR Marques Colston.  Seattle would end the half with kicker Josh Brown getting a 52-yard field goal.  After a scoreless third quarter, the 'Hawks tried to rally in the fourth quarter, but all they could get was Hasselbeck's 22-yard TD pass to WR Nate Burleson.
[EX A]: How many different WR's and TE's did Drew Brees throw to for touchdowns?

[EX Q]: Passage: The Bishop of Rome, called the Pope, was important since the early days of Christianity because of the martyrdom of both the apostles Simon Peter and Paul of Tarsus there. The Bishops of Rome were also seen (and still are seen by Catholics) as the successors of Peter, who is considered the first Bishop of Rome. The city thus became of increasing importance as the centre of the Catholic Church. After the Decline of the Roman Empire in 476 AD, Rome was first under the control of Odoacer and then became part of the Ostrogothic Kingdom before returning to Byzantine Empire control after the Gothic War (535-554), which devastated the city. Its population declined from more than a million in 210 AD to 500,000 in 273 to 35,000 after the Gothic War (535-554), reducing the sprawling city to groups of inhabited buildings interspersed among large areas of ruins, vegetation, vineyards and market gardens. It is generally thought the population of the city until 300 A.D. was 1 million (estimates range from 2 million to 750,000)  declining to 750-800,000 in 400 A.D., 450-500,000 in 450 A.D. and down to 80-100,000 in 500 A.D.

[EX A]:
How many people did the population decline by from 273 until after the Gothic War in 554?
