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 Input:
Passage: The Japanese attempted to deny the Russians use of Port Arthur. During the night of 13-14 February, the Japanese attempted to block the entrance to Port Arthur by sinking several concrete-filled steamers in the deep water channel to the port, but they sank too deep to be effective. A similar attempt to block the harbour entrance during the night of 3-4 May also failed. In March, the charismatic Vice Admiral Makarov had taken command of the First Russian Pacific Squadron with the intention of breaking out of the Port Arthur blockade. On 12 April 1904, two Russian pre-dreadnought battleships, the flagship Petropavlovsk and the Pobeda, slipped out of port but struck Japanese mines off Port Arthur. The Petropavlovsk sank almost immediately, while the Pobeda had to be towed back to port for extensive repairs. Admiral Makarov, the single most effective Russian naval strategist of the war, perished on the battleship Petropavlovsk. On 15 April 1904, the Russian government made overtures threatening to seize the British war correspondents who were taking the ship Haimun into warzones to report for the London-based Times newspaper, citing concerns about the possibility of the British giving away Russian positions to the Japanese fleet. The Russians quickly learned, and soon employed, the Japanese tactic of offensive minelaying. On 15 May 1904, two Japanese battleships, the Yashima and the Hatsuse, were lured into a recently laid Russian minefield off Port Arthur, each striking at least two mines. The Hatsuse sank within minutes, taking 450 sailors with her, while the Yashima sank while under tow towards Korea for repairs. On 23 June 1904, a breakout attempt by the Russian squadron, now under the command of Admiral Wilgelm Vitgeft, failed. By the end of the month, Japanese artillery were firing shells into the harbour.

Ex Output:
How many days passed between the two Russian pre-dreadnaught battleships struck mines and the two Japanese battleships triking mines?

Passage: Still trying to acquire their first win of the season, the Bengals flew to Reliant Stadium for a Week 8 duel with the Houston Texans.  In the first quarter, Cincinnati's struggles continued as Texans WR Jacoby Jones returned a punt 73 yards for a touchdown.  The Bengals responded with kicker Shayne Graham getting a 43-yard field goal.  In the second quarter, Houston increased its lead as QB Matt Schaub completed a 6-yard TD pass to WR David Anderson.  Cincinnati closed out the half with Graham nailing a 32-yard field goal. In the third quarter, the Texans began to pull away as Schaub completed a 7-yard and a 39-yard TD pass to WR Kevin Walter.  In the fourth quarter, Houston sealed the win with RB Steve Slaton getting a 20-yard TD run. With yet another loss, the Bengals would fall to 0-8 and start a season with such a record for the first time since 1994.

Ex Output:
How many losses did the Bengals start this game with?

Passage: Within days of Boleslaw's murder, Casimir III of Poland invaded the principality to save Polish merchants and Catholic residents from attacks in Lviv. In June 1340, Casimir returned with a larger army. After four weeks he reached an agreement with local nobles and their leader Dmytro Dedko: in return for their services, local nobles would enjoy protection from the Polish king. However, the agreement was short-lived. The data is sparse, but it seems that Galicia-Volhynia was divided between the Lithuanians  and local nobles . During the winter 1340-1341, the Golden Horde  attacked Poland and reached Lublin as a result of diminished tribute from the principality to the Mongol khan. The raid weakened Polish influence in the principality. Eufemija, Boleslaw's widow, was drowned in the Vistula in winter 1342 to keep her out of the succession disputes. Detko, who managed to play Poles, Lithuanians, and Mongols against each other, disappeared from written sources in 1344. The same year direct conflict between Poland and Lithuania renewed, but soon a peace treaty was signed: Volhynia was assigned to Liubartas and Galicia to Casimir.

Ex Output:

How did Boleslaw's widow die?
