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: 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.

Output: Approximately how many years did it take for the Byzantine fleet to be destroyed after August 1348?


Input: Consider Input: Passage: The second divisional game of the year for the 3-0 Bears, looking for their first 4-0 start in seven seasons, took place at Ford Field against the 2-1 Detroit Lions. Since 2001, the Bears had won 17 of the meetings between the two, compared to Detroit's 9. The Bears defense, ranked 19th in scoring defense with 24.7 points per game and 25th in yards allowed with 383.0, had to keep up with the Lions' 4th-ranked offense, who recorded 410.7 yards per game 27.3 PPG, sixth in the league. The Lions also had running back Reggie Bush return from a knee injury; Bush had recorded 260 yards and a touchdown in the first two games. However, the Lions' leading receiver Nate Burleson broke his arm in a car accident, which meant additional focus on Calvin Johnson for the Bears. Expectations were for Charles Tillman to cover Johnson, who was limited by Tillman to 15 catches, no touchdowns and an average of 62.3 receiving yards in the last three games. Although Tillman had suffered groin and knee injuries that left him questionable for the game, he was later listed as active against the Lions. However, Johnson recorded 40 catches for 20+ yards in 2012, and the Bears allowed the Steelers to gain 20 yards or more in nine plays. To attempt to combat Johnson, the Bears switched from the pressure defense run in the first three games to the cover 2. In the battle on the line of scrimmage, the Bears had to contain Ndamukong Suh and Nick Fairley, while the Lions had to protect Matthew Stafford from Julius Peppers and Corey Wootton. Offensively, the Bears also had to survive the crowd, who helped the Bears commit nine false start penalties in 2011. Neither team scored a touchdown in the first quarter, instead both scoring field goals, which extended into the first score of the second quarter. Later in the quarter, Matt Fort&#233; scored on a 53-yard run, allowing the Bears to take the 10-6 lead. However, after a David Akers field goal, the Lions would score three unanswered touchdowns, all within 3 minutes, 26 seconds: Micheal Spurlock's 57-yard punt return led to Matthew Stafford's 1-yard run, while Jay Cutler was intercepted by Glover Quin, which set up Stafford's 2-yard pass to Calvin Johnson; finally, the Lions scored after Reggie Bush found a hole and hurdled over Bears' safety Major Wright en route to a 37-yard touchdown. The 27 points scored in the quarter was the most by the Lions since September 30, 2007 against the Bears. The Bears ended the half with a field goal, but continued to trail 30-13. After the Bears kicked a field goal in the third quarter, Cutler was intercepted again, this time by Louis Delmas. However, Chicago regained possession after Stafford's pass to Johnson was kicked and caught by Wright. Three plays later, Cutler was sacked by Ndamukong Suh, and fumbled; the ball was picked up by Nick Fairley, who ran four yards for the touchdown. In the fourth quarter, Akers kicked another field goal to put the Lions up 40-16. Afterwards, the Bears began to mount a charge, with Cutler throwing a 14-yard touchdown pass to Alshon Jeffery with less than four minutes in the game, followed by a two-point conversion on another pass to Jeffery. With 43 seconds remaining, a ten-yard pass to Earl Bennett and a two-point conversion off a throw to Brandon Marshall drew the Bears within eight points, but the eventual onside kick was recovered by Lions receiver Kris Durham, allowing the Lions to clinch the 40-32 victory. Statistically, the Bears offense struggled. Cutler completed 27 of 47 passes for 317 yards, two touchdowns, three interceptions and a 65.6 passer rating. Cutler's three interceptions and fumble tied his turnover amount in the first three games. The offense also had trouble on third down; despite being ranked ninth in third down efficiency, the Bears failed to convert until there were 47 seconds left in the game to end the game converting just 1 of 13 third downs.

Output: How many turnovers did Cutler have?


Input: Consider Input: Passage: The Sudetes are a geologically diverse mountain range that stretches for 280 kilometres  from the Lusatian Highlands in the west and to the Moravian Gate in the east. They are topographically divided into Western, Central and Eastern Sudetes. The Lower Silesian section of the Sudetes comprises the Jizera Mountains , where the tripoint with Upper Lusatia and Bohemia is located near the Smrk summit, along with the adjacent Karkonosze Krkonoše  ; Rudawy Janowickie ; Owl Mountains ; Stone Mountains ; Wałbrzych Mountains  and the Kaczawskie Mountains  with Ostrzyca, 501 m or 1,644 ft - they surround the Jelenia Góra valley, 420-450 m or 1,380-1,480 ft; Ślęża Massif , massive of Orlické hory, Králický Sněžník south of historical Kladsko Polish: Klodzsko), Rychlebské hory and Jeseníky   .


Output: How many areas/mountains is the Lower Silesian section made of?
