instruction:
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.
question:
Passage: With the end of the "crack epidemic" in the mid-1990s and with the initiation of aggressive policing under mayors David Dinkins and subsequently Rudolph Giuliani, crime in Harlem plummeted. In 1981, 6,500 robberies were reported in Harlem; robberies dropped to 4,800 in 1990 during David Dinkins mayoralty. By 2000, only 1,700 robberies were reported, and by 2010, only 1,100 were reported. There have been similar changes in all categories of crimes tracked by the New York City Police Department. In the 32nd Precinct, which services Central Harlem above 127th Street, for example, between 1990 and 2013, the murder rate dropped 89.4%, the rape rate dropped 67.5%, the robbery rate dropped 74.2%, burglary dropped 93.4%, and the total number of crime complaints dropped 77.6%.
answer:
How many fewer robberies were reported to the New York City Police Department in 2010 than in 2000?

question:
Passage: Until the death of Duke Mestwin II in 1294, the Duchy of Pomerelia on the Baltic coast, stretching from the border with the Imperial Duchy of Pomerania in the west to the Prussian territory of the Order state at the Vistula river in the east, had been held by the Samborides dynasty, liensmen of the Polish Piast rulers. Przemys II, King of Poland since 1295, incorporated Pomerelia into the Lands of the Polish Crown - against the protest of the Imperial Margraviate of Brandenburg referring to the Treaty of Arnswalde signed with Duke Mestwin in 1269. The next year, the Ascanian margraves instigated the kidnapping and killing of King Przemys, probably backed by King Wenceslaus II of Bohemia, who aimed for the Polish crown. King Wenceslaus II prevailed against his Piast rival Wadysaw I the Elbow-high and was crowned King of Poland in 1300. He ruled in Pomerelia with the assistance of the local Swenzones noble family. Upon the assassination of his son Wenceslaus III in 1306, the Premyslid dynasty became extinct and Duke Wadysaw was able to occupy the Pomerelian lands. The Swenzones, fearing for their assets and sinecures, called for Margrave Waldemar of Brandenburg, whose troops occupied the territory up to the city of Gdansk. Wadysaw reacted by calling the forces of the Teutonic Order, who under the command of Heinrich von Plotzke in 1308 re-conquered Gdansk and most of Pomerelia. However, after the Teutonic takeover they denied the handover to Wadysaw, as the duke refused to pay the requested expense allowance. Instead they concluded the 1309 Treaty of Soldin with Margrave Waldemar, whose resistance from the beginning had been relatively weak and who now was willing to sell off his claims to Pomerelia.
answer:
How many years did it take for the Premyslid dynasty to become extinct?

question:
Passage: By 2007, 56.8% of evacuees had found jobs, 22.3% were unemployed and seeking work, and 31.2% of evacuees were unemployed and living off government benefits rather than seeking work. The average monthly salary among the evacuees was NIS 5,380 (about $1,281), a slight rise of 2.1 percent from the average salary the year before. This was, however, a sharp drop of 39% from the settlers average monthly income before the disengagement. The average salary among evacuees was lower than the general average, as compared to above average before the disengagement. In addition to a drop in salary, the evacuees also suffered a drop in their standard of living due to the increased price of goods and services in their places of residence as compared to the settlements. Following the disengagement, settlers were temporarily relocated to hotels, sometimes for as long as half a year, before moving to mobile homes as temporary housing known as caravillas, before they could build proper homes. By June 2014, about 60% of evacuees were still living in these caravillas. Only 40% had moved to permanent housing, although construction of permanent settlements for the evacuees continues to progress. By July 2014, eleven towns for the evacuees had been completed with the expellees joining ten additional towns. Many of the permanent settlements under construction were given names reminiscent of the former Gaza settlements. By August 2014, unemployment among evacuees had dropped to 18%. In 2010 a bill was introduced in the Knesset providing a basic pension to business owners whose businesses collapsed.
answer:
How many more evacuees were receiving benefits than were seeking work in 2007?
