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: Over the years the city has been home to people of various ethnicities, resulting in a range of different traditions and cultural practices. In one decade, the population increased from 427,045 in 1991 to 671,805 in 2001. The population was projected to reach 915,071 in 2011 and 1,319,597 by 2021. To keep up this population growth, the KMC-controlled area of  has expanded to  in 2001. With this new area, the population density which was 85 in 1991 is still 85 in 2001; it is likely to jump to 111 in 2011 and 161 in 2021.
[EX A]: How many more people populated the city in 2001 than in 1991?

[EX Q]: Passage: Spanish conquest of the Iberian part of Navarre was commenced by Ferdinand II of Aragon and completed by Charles V in a series of military campaigns extending from 1512 to 1524, while the war lasted until 1528 in the Navarre to the north of the Pyrenees. Ferdinand the Catholic was in 1512 both king of Aragon and regent of Castile. When Pope Julius II declared a Holy League against France in late 1511, Navarre tried to remain neutral. Ferdinand used this as an excuse to attack Navarre, conquering it while its potential protector France was beset by England, Venice, and Ferdinand's Italian armies. Several attempts were made to reconquer Iberian Navarre starting right after the Castilian invasion , notably a halfhearted reconquest attempt in 1516 and a fully-fledged French-Navarrese reconquest campaign in 1521. All were defeated by the Spanish, and clashes came to halt to the north of the Pyrenees in 1528, when the Spanish troops withdrew from Lower Navarre. The Treaty of Cambrai between Spain and France in 1529 sealed the division of Navarre along the Pyrenees, while the independent Kingdom of Navarre survived in Lower Navarre ruled by the lineage of the Albrets united to their principality of Béarn, showing close links with France. The kingdom was absorbed into France in 1620 .
[EX A]: From what year to what year were the operations of war conducted?

[EX Q]: Passage: Founded in 1861 by Edmund Chojecki (writing under the pen name "Charles Edmond") and Auguste Nefftzer, Le Temps was under Nefftzers direction for ten years, when Adrien Hébrard took his place, and for nearly 45 years directed the newspaper with an iron hand until his death in 1914. He was succeeded by his sons Émile (1914), and Adrien Jr. (1925) and by Louis Mills (1929). Soon after Mills death in 1931, Le Temps became a public limited company. Adrien Hébrard and his successors left substantial freedom to the editorial room and the newspaper had the reputation of keeping its journalists for a long time. Le Temps always remained moderate politically. The early issues of the newspaper reflected Nefftzers liberal philosophy had considerable trouble achieving readership. He had to frequently turn to friends in Alsace who were able to help support Le Temps financially. However, circulation continued to grow, from scarcely 3,000 in 1861, to 11,000 in 1869, 22,000 in 1880, 30,000 in 1884, 35,000 in 1904. During the interwar period it varied between 50,000 to 80,000. Despite this comparatively modest circulation, Le Temps soon became the most important newspaper of the Third French Republic particularly among the French political and economic elite. The political and diplomatic information and commentaries contained in this quality newspaper, "serious to the point of boredom", also carried considerable clout elsewhere in Europe.
[EX A]:
How many more people were subscribed to the newspaper in 1904 than in 1861 and 1880 combined?
