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.

Input: Consider Input: Passage: The Lines of Communication were English Civil War fortifications commissioned by Parliament  and built around London between 1642 and 1643 to protect the capital from attack by the Royalist armies of Charles I. In 1642 some basic fortifications were built, in the form of street barricades and small earthworks. In 1643 a major construction effort was made, to provide a comprehensive ring of fortifications around the city. Much of the work was done by volunteer labour, organized by the trained bands and the livery companies. Up to 20,000 people are thought to be involved, and the works were completed in under two months. The fortifications failed their only test when the New Model Army entered London in 1647, and they were levelled by Parliament the same year.

Output: How many months did it take them to build The Lines of Communication?


Input: Consider 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%.

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


Input: Consider Input: Passage: In 2011, Macaus free-market economy produced total exports of US$1.119 billion (MOP 8.94 billion) and consisted mainly of clothing, textiles, footwear, toys, electronics, machinery and parts. Total imports for the same period reached US$8.926 billion (MOP 71.32 billion), and consisted mostly of raw materials and semi-manufactured goods, consumer goods (foodstuffs, beverages, tobacco), capital goods, mineral fuels and oils. Macaus primary export partner in 2011 was Hong Kong (44.6%). Other exports go to Mainland China (15.9%) and United States (7.9%). Macau import partners are Mainland China (30.4%), Hong Kong (12%), France (10.4%), Switzerland (7.5%), Italy (7.5%), Japan (6.2%), and United States (6.1%).


Output: From which countries did Macau import between 6 to 8% of their goods?
