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: In order to regain control of the custom duties, the emperor John VI Kantakouzenos made preparations to lower Constantinople's duties and most tariffs to undercut the Genoese in Galata. Still recovering from the civil war of 1341-1347, the emperor, with great difficulty, raised 50,000 hyperpyra from private sources  for a shipbuilding program for the expected war to come. When the tariffs and custom duties were finally lowered, merchant shipping coming through the strait bypassed Genoese Galata and diverted their ships across the Golden Horn to Byzantine Constantinople. The Genoese, financially hard-hit from this policy, declared war on the Empire, and in August 1348, a flotilla of ships sailed across the Horn and attacked the Byzantine fleet; despite their large scale preparations, the Byzantine fleet was destroyed by early 1349. The Byzantines retaliated by burning wharves and warehouses along the shore and catapulted stones and burning bales of hay into Galata, setting major parts of the city on fire. After several weeks of fighting, plenipotentiaries from Genoa came and negotiated a peace agreement. The Genoese agreed to pay a war indemnity of 100,000 hyperpyra and evacuated the land behind Galata which they illegally occupied; last, they promised never to attack Constantinople. In return the Byzantines surrendered nothing, but the Genoese custom duties remained in effect.
Example Output: Approximately how many years did it take for the Byzantine fleet to be destroyed after August 1348?

Example Input: Passage: After the Turkish disaster at Vienna in September 1683, Austria and Poland formed an alliance to push the Turks south ). In 1686 Russia joined in ). After the Turks were pushed out of Hungary in 1687 fighting was inconclusive. In the Crimean campaigns of 1687 and 1689 the Russians failed in an attempt to invade Crimea. In 1695 Russia tried to take some forts on the lower Dnieper. By the treaties of 1699/1700 Turkey lost Hungary to Austria, Podolia to Poland and Azov, temporarily, to Russia.
Example Output: How many nations allied against Turkey?

Example Input: Passage: The Steelers returned home after a tough road loss to the Bengals to take on the Bears.  The first quarter was all Bears as they scored 17 unanswered points with Robbie Gould nailing a 47-yard field goal for a 3-0 lead followed up by Matt Forte's 5-yard touchdown run to make the score 10-0 and then Michael Bush's 1-yard touchdown run for a 17-0 lead.  The Steelers managed to get on the board in the 2nd quarter when Shaun Suisham nailed a 27-yard field goal to shorten the lead to 17-3, however the Bears increased their lead when Major Wright returned an interception 38 yards for a touchdown to make the score 24-3.  The Steelers came within 14 points at halftime as Ben Roetlisberger found Antonio Brown on a 33-yard touchdown pass to  shorten the score 24-10.  After the break, Gould kicked a 32-yard field goal increasing the Bears' lead to 27-10, but the Steelers answered with 13 straight points starting in the 3rd heading into the 4th quarter as Suisham nailed a 36-yard field goal for a 14-point deficit 27-13 and then a 21-yard pass to Brown from Roethlisberger again shortening the lead to 7 at 27-20.  In the 4th quarter, the Steelers came within 4 points as Suisham nailed a 44-yard field goal to make the score 27-23.  However, the Bears were able to seal the victory with Jay Cutler's 17-yard pass to Earl Bennett for a score of 34-23 and then Julius Peppers' 42-yard fumble return for a touchdown (with a failed PAT) for a final score of 40-23. With the loss, the Steelers dropped to 0-3 but on a positive note the team's 21-point deficit is the largest erased deficit in the franchise's history.  Though on the negative side the Browns won earlier in the day leaving the team in last in the AFC North.
Example Output:
How many field goals did Gould make?
