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.

[Q]: 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.
[A]: How many days passed between the two Russian pre-dreadnaught battleships struck mines and the two Japanese battleships triking mines?


[Q]: Passage: Due to a conflict involving the Orioles' schedule, the Ravens opened the regular season on the road against the Broncos in what would be the first time a defending Super Bowl champion team has done so since the Buccaneers in 2003 when they opened their regular season against the Eagles.  This would be a rematch of last year's AFC Divisional game. The Ravens drew first blood when Joe Flacco found Vonta Leach on a 2-yard touchdown pass to take the lead 7-0 in the first quarter for the only score of the period.  The Broncos would tie the game in the 2nd quarter with Peyton Manning finding Julius Thomas on a 24-yard pass to take the game to 7-7.  The Ravens moved back into the lead when Ray Rice ran for a 1-yard touchdown to make the score 14-7.  Peyton would find Julius again on a 23-yard pass to make the score 14-14 for another tie before the Ravens kicker Justin Tucker nailed a 25-yard field goal to make the score 17-14 at halftime.  In the 3rd quarter, the Broncos went right back to work as Peyton found Andre Caldwell on a 28-yard touchdown pass to take a 21-17 lead followed up with finding Wes Welker on 2 consecutive passes from 5 yards and 2 yards out for an increase in the lead first to 28-17 and then to 35-17.  Later on in the quarter, Peyton would find Demaryius Thomas on a 26-yard pass to increase the lead to 42-17.  The Ravens tried to rally a comeback in the last quarter, with Flacco finding Marlon Brown on a 13-yard pass to shorten the Broncos' lead 42-24 followed up by Tucker's 30-yard field goal to make the score 42-27.  However, the Broncos wrapped things up in the game when Peyton found D. Thomas again on a 78-yard pass to make the final score 49-27.  The Ravens began their season 0-1 for the first time under John Harbaugh as head coach and Joe Flacco as their starter.  They also lost their first regular season opening game since 2007 as well as becoming the 2nd straight defending Super Bowl champion team to lose their season opener.
[A]: How many field goals did the Ravens have?


[Q]: Passage: The Bucs went to the Georgia Dome for a Week 2 contest against their division rival, the Atlanta Falcons. Historically, the Buccaneers had been able to effectively contain Falcons' QB Michael Vick, shutting down the Falcons' offense in the process. However, the Bucs' performance here had not improved much from Week 1. The defense was unable to stop the running duo of Vick and RB Warrick Dunn, whose combined performance netted 261 yards, and 306 for Atlanta as a team&#8212;a new Falcons team record. Also illustrating their sharp fall in performance from their #1 NFL ranking the previous season, the Bucs' defense also allowed a 1-yard QB TD run by Vick and a 4-yard TD pass to RB Fred McCrary. Bucs QB Chris Simms continued to struggle, throwing another three interceptions, while Carnell Williams was held to just 37 yards on 15 carries. The Bucs' only points came on a chip-shot 22-yard field goal by kicker Matt Bryant.

How long were each of the touchdowns in the game?
