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.

[Q]: 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%.
[A]: How many fewer robberies were reported to the New York City Police Department in 2010 than in 2000?


[Q]: Passage: Hoping to increase their current winning streak the Titans flew to Qualcomm Stadium for an AFC duel with the Chargers. In the first quarter the Titans took the lead when the Chargers' punt was blocked by Nick Schommer out of bounds for a safety. The Chargers replied with FB Mike Tolbert getting a 1-yard TD run. The Titans went on a scoring rally with kicker Rob Bironas nailing a 21-yard field goal, followed in the second quarter by QB Vince Young completing a 1-yard TD pass to TE Craig Stevens. They increased their lead with RB Chris Johnson getting a 29-yard TD run. The Chargers went on a scoring rally with RB Ryan Mathews making a 7-yard TD run, followed in the third quarter by kicker Kris Brown making a 34-yard field goal. Then QB Philip Rivers completed a 48-yard TD pass to TE Antonio Gates, and then Brown made a 36-yard field goal. The Titans tried to come back with Young finding WR Nate Washington on a 71-yard TD pass (with a failed 2-point conversion), but couldn't do anything after Rivers got a 13-yard TD pass to RB Darren Sproles.
[A]: From what distance did two players score touchdowns?


[Q]: Passage: Sporadic and isolated outbursts by Tibetans against the Chinese continued especially during the unrest between September 1987 until March 1989 in the Tibetan areas of the PRC. But it wasn't until 2008 that a large-scale and coordinated uprising erupted coinciding with international protests accompanying the Olympics torch relay that would end in Beijing where the 2008 Summer Olympics were held. What originally began as an annual observance of Tibetan Uprising Day turned into street protests by large numbers of monks from various monasteries for several days. Crowd control and arrests escalated the tensions eventually setting off a riot by thousands of Tibetans in the Ramoche section of Lhasa on March 14, 2008. When the police fled the scene, rioters looted and burned more than 1200 Chinese shops, offices, and residences and set fire to nearly 100 vehicles. In the end, an estimated 22 were dead and 325 injured, mostly Han. Total damage was estimated at $40 million USD. Eventually the paramilitary People's Armed Police were sent in and 50-100 Tibetan rioters were killed before things quieted down. Meanwhile, in the Gansu Province, a demonstration by 400 monks were met with force that ignited riots by more than 5000 Tibetans who again burned down the establishments of local Han and Hui people before security forces arrived.
[A]:
Did the rioters burn more Chinese shops, offices, and residences or vehicles in the Ramoche riot?
