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: 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.

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


Question: Passage: The Bengals traveled to Minneapolis to take on the Vikings.  The Vikes dominated the majority of the game starting in the first quarter when they scored 3 times:  Latavius Murray ran for a 1-yard touchdown, Eric Kendricks intercepted Andy Dalton and returned it 31 yards for a touchdown, and then Kai Forbath kicked a 53-yard field goal to make it 17-0.  They made it 24-0 in the second quarter before halftime when Case Keenum found Stefon Diggs on a 20-yard pass.  In the third quarter, Forbath put a 35-yard field goal through to make it 27-0 for the only score.  This would be followed up by Keenum finding Kyle Rudolph in the fourth quarter to make it 34-0.  The Bengals score the last points of the game when Giovani Bernard ran for a 7-yard touchdown to make the final score 34-7. With the loss, the Bengals dropped to 5-9.  The team would have consecutive losing seasons for the first time since 2007 and 2008.  Andy Dalton also tied his career-high for most games started and lost in a single season.

Answer: How many field goals did Forbath make?


Question: Passage: The Chargers (4-6) fell three games behind Denver (7-3) for the division lead after losing to them, 30-23. Denver linebacker Von Miller had three sacks and forced two fumbles as the defense rattled Rivers. "This is the best defensive team they've had since I've been playing them," said Rivers. The Chargers offense was shut out in the first half. Their first 12 possessions resulted in 10 punts and two turnovers. Rivers was 9-for-20 for 60 yards and an interception, and the running game had only 8 yards on 11 attempts. The Chargers first 9 points of the game were scored by the defense&#8212;an interception returned for a touchdown by Eric Weddle, and a safety by Shaun Phillips. Rivers threw for 198 of his 258 yards in the second half while throwing two touchdowns. Manning finished the game with 270 yards and three touchdown for Denver. Denver swept the season series against the Chargers, giving them the advantage in a tiebreaker with San Diego if needed. "They're not losing four of six, I can guarantee you that", Rivers said in conceding the division. He was part of the 2008 team that trailed Denver by three games with three remaining before winning the division as the Broncos collapsed.

Answer:
How many interceptions did Rivers throw in the first half?
