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.

Q: Passage: During the Democratic Kampuchea days, the 68,000-member Khmer Rouge-dominated CPNLAF  force, which completed its conquest of Phnom Penh, Cambodia in April 1975, was renamed the RAK . This name dated back to the peasant uprising that broke out in the Samlot district of Battambang Province in 1967. Under its long-time commander and then Minister of Defense Son Sen, the RAK had 230 battalions in 35 to 40 regiments and in 12 to 14 brigades. The command structure in units was based on three-person committees in which the political commissar ranked higher than the military commander and his deputy. Cambodia was divided into zones and special sectors by the RAK, the boundaries of which changed slightly over the years. Within these areas, the RAK's first task was the peremptory execution of former Khmer National Armed Forces  officers and of their families, without trial or fanfare to eliminate KR enemies. The RAK's next priority was to consolidate into a national army the separate forces that were operating more or less autonomously in the various zones. The Khmer Rouge units were commanded by zonal secretaries who were simultaneously party and military officers, some of whom were said to have manifested "warlord characteristics". Troops from one zone frequently were sent to another zone to enforce discipline. These efforts to discipline zonal secretaries and their dissident or ideologically impure cadres gave rise to the purges that were to decimate RAK ranks, to undermine the morale of the victorious army, and to generate the seeds of rebellion. In this way, the KR used the RAK to sustain and fuel its violent campaign.

Afterwards, San Francisco would close out the half with a 50-yard field goal from kicker Joe Nedney.  After a scoreless third quarter, the Eagles added onto their lead in the fourth quarter as safety Quintin Mikell returned a fumble 52 yards for a touchdown.  The 49ers began to rally as Smith connected a 7-yard touchdown pass to tight end Vernon Davis, yet Akers came right back as he gave Philadelphia a 45-yard field goal.  San Francisco tried to rally as Smith completed a 1-yard touchdown pass to running back Frank Gore, yet Philadelphia's defense held on to preserve the victory.

Q: Passage: In 1466, perhaps 40,000 people died of the plague in Paris. During the 16th and 17th centuries, the plague was present in Paris around 30 per cent of the time. The Black Death ravaged Europe for three years before it continued on into Russia, where the disease was present somewhere in the country 25 times between 1350 and 1490. Plague epidemics ravaged London in 1563, 1593, 1603, 1625, 1636, and 1665, reducing its population by 10 to 30% during those years. Over 10% of Amsterdams population died in 1623–1625, and again in 1635–1636, 1655, and 1664. Plague occurred in Venice 22 times between 1361 and 1528. The plague of 1576–1577 killed 50,000 in Venice, almost a third of the population. Late outbreaks in central Europe included the Italian Plague of 1629–1631, which is associated with troop movements during the Thirty Years War, and the Great Plague of Vienna in 1679. Over 60% of Norways population died in 1348–1350. The last plague outbreak ravaged Oslo in 1654.
