TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: From what year did the name RAK originate?

PROBLEM: Passage: His first year as a starter was 2000, when he recorded 83 catches for 944 yards and 4 touchdowns. In 2001 New England Patriots season he, alongside Tom Brady, led the Patriots to their first ever Super Bowl championship, recording 101 catches during the season for 1,199 yards and 5 touchdowns, setting the franchise record for receptions and earning his first and only trip to the Pro Bowl. He also returned 29 punts for 413 yards and 2 touchdowns, giving him a league-leading 14.2 yards per return average. During the AFC Championship Game at Heinz Field against the Pittsburgh Steelers in the NFL playoffs, 2001-02 that season, Brown returned a crucial punt for a touchdown which provided the winning margin, adding to the two he returned for touchdowns during the regular season. He also scooped up a blocked field goal attempt in that game, and made a lateral pass to teammate Antwan Harris, which completed a second special teams touchdown.  In 2002, he recorded 97 receptions for 890 yards and 3 touchdowns. In 2003 New England Patriots season, he had 40 catches for 472 yards, helping his team back to Super Bowl XXXVIII.

SOLUTION: Did Brown have a higher average yards per catch in the 2000 season or the 2001 season?

PROBLEM: Passage: Air temperature is stable over the year at 26 °C in February and 27 °C in August. Precipitation is as high as 3,000 mm/year and mostly occurs in summer. Sea currents are south-easterly and easterly in winter and south-westerly and westerly in summer. The average surface water temperature is 26-28 °C in February and 29 °C in May. The water temperature is constant at 4.8 °C at the depths of 1,600 m and below. Salinity is 31.5-32.5 (parts per thousand) in summer and 30.0-33.0 in winter in the southern part. In the northern part, it decreases to 20-25‰ due to the inflow of fresh water from the Irrawaddy River. Tides are semidiurnal (i.e., rising twice a day) with an amplitude of up to 7.2 meters.

SOLUTION:
Does salinity have a larger range in summer or winter in the south?
