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: Economic; The importance of trade and economic interests to the participants is often under estimated; contemporaries viewed Dutch and English support for the Habsburg cause as primarily driven by a desire for access to the Spanish American markets. Modern economics generally assumes a constantly growing market whereas the then dominant theory of Mercantilism viewed it as static. As a result, increasing your share of trade implied taking it from someone else, with the government's role being to restrict foreign competition. Trade was often used as a policy weapon; between 1690-1704, English import duties increased by 400%, while the 1651-1663 Navigation Acts were a major factor in the Anglo-Dutch Wars. On 6 September 1700, France banned the import of English manufactured goods like cloth and imposed prohibitive duties on a wide range of others. Military; the armies engaged in the Nine Years War often exceeded 100,000 men and proved too large for the pre-industrial economies of its participants. Those of 1701-1714 averaged around 35,000 - 50,000 but a dependence on water-borne transport accentuated the importance of rivers like the Rhine in Germany or the Adda in Northern Italy. Reliance on the local countryside for resupply limited operations in poor areas like Northern Spain; these factors confined campaigns to the same general areas.

Answer: How many years did the English import duties increase by 400%?

Question: Passage: AH-1 Cobras were in use by the Army during the Tet offensive in 1968 and through to the end of the Vietnam War. Cobras provided fire support for ground forces, escorted transport helicopters and other roles, including aerial rocket artillery (ARA) battalions in the two Airmobile divisions. They also formed "hunter killer" teams by pairing with OH-6 Cayuse scout helicopters. A team featured one OH-6 flying slow and low to find enemy forces. If the OH-6 drew fire, the Cobra could strike at the then revealed enemy. On 12 September 1968, Capt. Ronald Fogleman was flying an F-100 Super Sabre when the aircraft was shot down and he ejected 200 miles north of Bien Hoa. Fogleman became the only pilot to be rescued by holding on to an Army AH-1Gs deployed gun-panel door. Bell built 1,116 AH-1Gs for the U.S. Army between 1967 and 1973, and the Cobras chalked up over a million operational hours in Vietnam; the number of Cobras in service peaked at 1,081. Out of nearly 1,110 AH-1s delivered from 1967 to 1973 approximately 300 were lost to combat and accidents during the war. The U.S. Marine Corps used AH-1G Cobras in Vietnam for a short time before acquiring twin-engine Bell AH-1 SuperCobra.

Answer: Approximately how many of the 1110 AH-1s delivered from 1967 to 1973 were lost per year on average?

Question: Passage: Taylor won the inaugural 2014 Perth Darts Masters after beating Van Gerwen in the final 11-9 whilst averaging 105.08. He then defended his 2014 Sydney Darts Masters title by beating Stephen Bunting 11-3 in the final. In the quarter-finals of the 2014 World Grand Prix (darts), Taylor lost 3-1 against James Wade. This was the first time that Wade had beaten Taylor in a major televised knockout tournament. At the 2014 European Championship (darts), Taylor lost 10-9 in a thriller to Stephen Bunting. Taylor comfortably progressed to the final of the 2014 Grand Slam of Darts and a meeting with Dave Chisnall. Despite taking an initial 5-0 lead, the final was by far his closest match of the event as Chisnall fought back to 10-10, before Taylor rediscovered his best form to win another five unanswered legs and seal his sixth Grand Slam title 16-13.

Answer:
How many fewer points did Bunting have against Taylor versus how many Van Gerwen had against Taylor?
