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: 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%.
Example Output: How many fewer robberies were reported to the New York City Police Department in 2010 than in 2000?

Example Input: Passage: The uprising was ultimately crushed by the Russian authorities. Official reports indicated 151 civilian deaths  and 150 wounded; unofficial reports spoke of over 200 fatalities and between 800 and as many as 2,000 wounded. The Łódź uprising was neither the first nor the last disturbance in what has been described in Polish historiography as the revolution in the Kingdom of Poland —various protests and strikes occurred in major Polish cities under Russian control throughout the year—but it would be the most dramatic one. In September 1905, two PPS activists would assassinate Juliusz Karol Kunitzer, owner of the Heinzel & Kunitzer factory, known for his poor treatment of workers. Strikes in Łódź continued until mid-1906, when the large Russian military presence and mass layoffs of striking workers from the factories finally pacified the city. Even afterward, Łódź was not a peaceful city; in the years 1910-1914 it was the site of a radical, anarchist and socialist group Rewolucyjni Mściciele labeled as "the most extreme, terrorist group in the history of Poland". The uprising was reported in the international press and recognized by socialist and communist activists worldwide.
Example Output: According to official reports, were more people killed or wounded?

Example Input: Passage: Hoping to rebound from their shutout home loss to the Jets, the Raiders flew to Qualcomm Stadium for a Week 8 AFC West rematch with the San Diego Chargers.  Oakland would trail in the first quarter as Chargers running back LaDainian Tomlinson got a 6-yard touchdown run.  The Raiders answered in the second quarter as running back Justin Fargas got a 5-yard touchdown run, but San Diego replied with quarterback Philip Rivers' 8-yard touchdown pass to wide receiver Vincent Jackson and Tomlinson's 10-yard touchdown run.  Afterwards, Oakland would close out the half as kicker Sebastian Janikowski got a 48-yard field goal. In the second quarter, the Raiders tried to rally as Janikowski nailed a 41-yard field goal in the third quarter and a 28-yard field goal in the fourth, but the Chargers pulled away with a 28-yard field goal from kicker Nate Kaeding. With the loss, Oakland fell to 2-6 entering their bye week.
Example Output:
How long was Janikowski's last field goal?
