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.

[EX Q]: 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.
[EX A]: How many years did the English import duties increase by 400%?

[EX Q]: Passage: Against the Baltimore Ravens in week twelve, the Bears wore their 1940s alternate uniforms. The Bears last played the Ravens in 2009, which ended with a Baltimore 31-7 victory. With Jay Cutler still out, Josh McCown continued to play as quarterback for the Bears, who had the eighth-best passing offense in the league with 261.7 yards per game, which competed against the Ravens' 18th-ranked pass defense. On the ground, the Ravens had the tenth-best rushing D with 102.6 rushing yards allowed per game, but offensively, had the 30th-ranked rushing offense, averaging just 73.1 yards per game, going against Chicago's defense which allowed 129.4 rushing yards per game. Against Joe Flacco, the Bears had the opportunity to force turnovers, as Flacco had thrown eleven interceptions in the previous nine games. For the Bears on offense, a liability was to protect McCown from Terrell Suggs and Elvis Dumervil, who combined for 17 of 32 sacks by the Ravens. Two parties had the majority favoring the Bears for the game: 10 of 13 ESPN analysts predicted a Bears victory, with Ron Jaworski, Seth Wickersham and Cris Carter being the only three to predict a win for Baltimore. CBS Sports analysts predicted the Ravens would win in a 5-4 vote. The Ravens opened the game with Ray Rice gaining a 47-yard run, his longest of the year up to that point (his previous highest in 2013 was 14 yards), which led to Rice's 1-yard run with 9:58 in the first. The Ravens added to the score with Justin Tucker's 52-yarder, bringing the score to 10-0. With 4:51 left in the first quarter, the game was suspended due to inclement weather, which included a tornado watch, which was eventually elevated to a tornado warning. Fans were ordered to evacuate the stands and enter the covered concourses, while the teams returned to the locker rooms. The evacuation marked the first time Soldier Field had an evacuation since the stadium's opening in 1921. The game resumed play at 3:25&#160;p.m. ET, after a 1-hour, 53 minute-delay. In the second quarter, Robbie Gould kicked a 20-yard field goal, and eventually, rookie defensive end David Bass escaped a chop block by Rice and intercepted Flacco, scoring on a 24-yard return and tying the game. The Ravens eventually scored on Torrey Smith's five yard touchdown catch, and after Flacco had a pass intercepted by Jon Bostic, Gould ended the half kicking a 46-yarder. After a scoreless third period, Matt Fort&#233; caught a 14-yard pass from McCown and scored with 10:33 in the fourth, the Bears finally taking the lead 20-17. Now behind by three, the Ravens engineered an 82-yard drive to Chicago's 2-yard line, but Rice failed to score twice, and a botched snap from Gino Gradkowski slowed down the Ravens, and Flacco's pass towards Smith was overthrown. As a result, the Ravens resorted to a 21-yard field goal with three seconds in regulation to force overtime. In overtime, Flacco's pass for Tandon Doss fell incomplete, and the Ravens punted to the Bears. McCown then completed a 43-yard pass to Martellus Bennett, and Gould kicked the game-winning 38-yard field goal with 8:41 remaining to win the game 23-20, which lasted five hours, 16 minutes.

[EX Q]: Passage: The Cowboys began their 2007 campaign at home against their NFC East rival, the New York Giants.  In the first quarter, Dallas trailed early as QB Eli Manning completed a 60-yard TD pass to WR Plaxico Burress to give New York an early 6-0 lead (botched hold on PAT).  Afterwards, the Cowboys got on the board with rookie kicker Nick Folk getting a 31-yard field goal.  In the second quarter, Dallas took the lead with RB Marion Barber getting an 18-yard TD run, while QB Tony Romo completed an 18-yard TD pass to TE Jason Witten.  Afterwards, the Giants would end up trailing by one at halftime, as Manning & Burress hooked up with each other again on a 4-yard TD pass, while kicker Lawrence Tynes got a 44-yard field goal. In the third quarter, Dallas responded with Romo completing a 22-yard TD pass to WR Terrell Owens.  New York would climb back with Tynes kicking a 48-yard field goal, but the Cowboys answered with Romo running into the end zone from 9 yards out.  In the fourth quarter, the Giants managed to try to come back with Tynes' 24-yard field goal, yet Dallas would reply with Romo & Owens hooking up with each other again on a 47-yard TD pass.  Just when it looked like New York was drawing closer with Manning's 9-yard TD pass to RB Derrick Ward (with a failed 2-point conversion) and his 10-yard TD pass to Burress, the Cowboys sealed the win with Romo completing a 51-yard TD pass to WR Sam Hurd.
