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: The kingdoms of France and Scotland had traditionally enjoyed a close diplomatic relationship, reflected in a defensive treaty signed between the two kingdoms in 1512. When Henry crossed the English Channel to campaign in France, the King of France activated the treaty, sending arms, money and military advisers to James IV of Scotland to encourage him to fulfil his obligations, in the hope that this would draw English resources away from the invasion of France. James crossed the border with a force of some 35,000 men, including 5,000 French advisers. He was opposed by an English force under the Earl of Surrey. The two sides met on September 9, 1513, near the village of Flodden. The Scottish army was heavily defeated, losing some 9,000 men and many nobles, including King James, the King's illegitimate son, and twelve earls.

SOLUTION: Did the kingdoms of France and Scotland have a treaty?

PROBLEM: Passage: German civilians were held as "reparations labour" by the USSR. Data from the Russian archives, newly published in 2001 and based on an actual enumeration, put the number of German civilians deported from Poland to the USSR in early 1945 for reparations labour at 155,262; 37% (57,586) died in the USSR. The West German Red Cross had estimated in 1964 that 233,000 German civilians were deported to the USSR from Poland as forced labourers, and that 45% (105,000) were dead or missing. The West German Red Cross estimated at that time that 110,000 German civilians were held as forced labour in the Kaliningrad Oblast, where 50,000 were dead or missing. The Soviets deported 7,448 Poles of the Armia Krajowa from Poland. Soviet records indicated that 506 Poles died in captivity. Tomasz Kamusella maintains that in early 1945, 165,000 Germans were transported to the Soviet Union. According to Gerhardt Reichling, an official in the German Finance office, 520,000 German civilians from the Oder-Neisse region were conscripted for forced labour by both the USSR and Poland; he maintains that 206,000 perished.

SOLUTION: How many more people did the West German Red Cross estimate were deported compared to the data from the Russian archives?

PROBLEM: Passage: After a series of Mongol invasions of Korea between 1231 and 1281, Goryeo signed a treaty in favor of the Mongols and became a vassal state. Kublai was declared Khagan of the Mongol Empire in 1260  and established his capital at Khanbaliq  in 1264. Japan at the time was ruled by the Shikken  of the Hōjō clan, who had intermarried with and wrested control from Minamoto no Yoriie, shōgun of the Kamakura shogunate, after his death in 1203. The inner circle of the Hōjō clan had become so preeminent that they no longer consulted the council of the shogunate ), the Imperial Court of Kyoto, or their gokenin vassals, and made their decisions at private meetings in their residences ). The Mongols also made attempts to subjugate the native peoples of Sakhalin—the Ainu, Orok, and Nivkh peoples—from 1260 to 1308.

SOLUTION:
After Kublai was declared Khagan, how many years passed until he established Khanbaliq?
