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.

Example Input: Passage: During the early months of World War I, Kars was a key military objective for the Ottoman army. Ismail Enver who pushed the Ottoman Empire into World War I, needed a victory against the Russians to defend his position. He collected an army on the eastern border. The army was badly defeated under Enver's command at the Battle of Sarikamish January 2, 1915 against Nikolai Nikolaevich Yudenich. This defeat was more due to the winter weather and bad planning, given the fact that Russians were actually preparing to evacuate Kars. With the loss of the eastern army, Ottoman defenses crumbled with further small battles and the Russian army succeeded in advancing as far west as Erzincan. The collapse of the Russian army after the 1917 revolution left only thinly spread Armenian units to resist the inevitable Ottoman counter-attack. Before the end of World War I in 1918, the Ottoman army reformed with what was left from the middle-east branch and tried to build a line between whatever seemed to be left on their east border. The newly declared First Republic of Armenia captured Kars in April 1918, which was eventually handed back by the future Soviet administration. That same year in March, the Baku Commune was established in the Azerbaijan Democratic Republic. The commune later became the Centrocaspian Dictatorship, in turn conquered by the Islamic Army of the Caucasus, then shortly by the Triple Entente and finally the Bolsheviks. Defeat on other fronts caused the Ottoman Empire to surrender and withdraw forces. Both the Armenian and Azerbaijani Republics ended up being part of the Soviet Union in 1920.
Example Output: How many groups conquered the Centrocaspian Dictatorship?

Example Input: Passage: The Census Bureaus 2006-2010 American Community Survey showed that (in 2010 inflation adjustment dollars) median household income was $52,056 (with a margin of error of +/- $3,048) and the median family income was $58,942 (+/- $4,261). Males had a median income of $33,306 (+/- $4,132) versus $37,265 (+/- $3,034) for females. The per capita income for the borough was $23,767 (+/- $1,013). About 12.2% of families and 16.8% of the population were below the poverty line, including 23.5% of those under age 18 and 16.0% of those age 65 or over.
Example Output: How many dollars is the household income with the addition to the marginal error?

Example Input: Passage: From the 1960s to the 1980s historians still considered 100,000 a reasonable estimate of the Jews killed and, according to Edward Flannery, many considered it "a minimum". Max Dimont in Jews, God, and History, first published in 1962, writes "Perhaps as many as 100,000 Jews perished in the decade of this revolution."  Edward Flannery, writing in The Anguish of the Jews: Twenty-Three Centuries of Antisemitism, first published in 1965, also gives figures of 100,000 to 500,000, stating "Many historians consider the second figure exaggerated and the first a minimum". Martin Gilbert in his Jewish History Atlas published in 1976 states "Over 100,000 Jews were killed; many more were tortured or ill-treated, others fled ..." Many other sources of the time give similar figures. Although many modern sources still give estimates of Jews killed in the uprising at 100,000 or more, others put the numbers killed at between 40,000 and 100,000, and recent academic studies have argued fatalities were even lower. A 2003 study by Israeli demographer Shaul Stampfer of Hebrew University dedicated solely to the issue of Jewish casualties in the uprising concludes that 18,000-20,000 Jews were killed of a total population of 40,000. Paul Robert Magocsi states that Jewish chroniclers of the 17th century "provide invariably inflated figures with respect to the loss of life among the Jewish population of Ukraine. The numbers range from 60,000-80,000  to 100,000 , but that "he Israeli scholars Shmuel Ettinger and Bernard D. Weinryb speak instead of the 'annihilation of tens of thousands of Jewish lives', and the Ukrainian-American historian Jarowlaw Pelenski narrows the number of Jewish deaths to between 6,000 and 14,000". Orest Subtelny concludes:.
Example Output:
According to Shaul Stampfer how many percentage of the total Jewish population was killed?
