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 United States Navy (USN) hoped to use the V-1710 in its rigid airships USS Akron (ZRS-4) and USS Macon (ZRS-5), but both were equipped with German-built Maybach VL-2 engines as the V-1710 was still in testing when the Macon was lost in February 1935 (the Akron having been lost in April 1933). The USAAC purchased its first V-1710 in December 1932. The Great Depression slowed development, and it was not until December 14, 1936 that the engine next flew in the Consolidated XA-11A testbed. The V-1710-C6 successfully completed the USAAC 150 hour Type certificate on April 23, 1937 at , the first engine of any type to do so. The engine was then offered to aircraft manufacturers where it powered the prototype Curtiss XP-37s. All entrants in the new pursuit competition were designed around it, powering the Lockheed P-38, Bell P-39 and Curtiss P-40. When war British Purchasing Commission asked North American Aviation to build the P-40 under license, NAA instead proposed their own improved aircraft design, using the V-1710 in their North American P-51 Mustang.
[A]: How many airships did the United States Navy (USN) hope to use the V-1710 in?


[Q]: Passage: On 2 May, 1687, a Russian army of about 132,000 soldiers, led by knyaz Vasily Golitsyn, left Okhtyrka on the Belgorod Line. On 30 May they were joined by 50,000 Left Bank Cossacks under hetman Ivan Samoilovich at the mouth of the Samora River where the Dnieper turns south. In the heat of summer, 180,000 men, 20,000 wagons and 100,000 horses set out down the east bank of the Dnieper. The huge force, which started too late and was perhaps not well organized,  could only travel about 10km per day. When the Russians reached the Konskiye Vody river on the west-flowing part of the Dnieper, they found that the Tatars has set fire to the steppe . After a few days of marching over burnt land, their horses were exhausted, they were short of water and 130 miles from their goal at Perekop, however Golitsyn built a fortress at Novobogoroditskoe at the junction of the Dnieper and the Samara. On 17 June they decided to turn back.
[A]: How many days after a Russian army of about 132,000 soldiers led by knyaz Vasily Golitsyn left Okhtyrka did they decide to turn back?


[Q]: Passage: Hoping to rebound from their last-second home loss to the Panthers, the Chargers flew to Invesco Field at Mile High for a Week 2 AFC West duel with the Denver Broncos.  In the first quarter, San Diego trailed early as FB Michael Pittman getting a 1-yard TD run, after a Philip Rivers pass to Chris Chambers was ruled an interception on the field. The Chargers challenged the ruling, but the replay system was inoperative to the officials, so the ruling on the field stood.  The 'Bolts would respond with kicker Nate Kaeding getting a 34-yard field goal.  In the second quarter, Denver increased its lead with QB Jay Cutler completing a 3-yard and a 14-yard TD pass to TE Tony Scheffler.  San Diego would immediately respond with RB Darren Sproles returning a kickoff 103 yard for a touchdown, yet the Broncos replied with kicker Matt Prater getting a 52-yard field goal.  The Chargers would strike at Denver's lead as QB Philip Rivers completing a 48-yard TD pass to WR Chris Chambers, yet the Broncos would end the half with Cutler completing a 6-yard TD pass to WR Brandon Marshall. In the third quarter, the 'Bolts began to rally as Rivers completed a 15-yard TD pass to Chambers, along with Kaeding nailing a 21-yard field goal.  In the fourth quarter, San Diego took the lead with Kaeding's 28-yard field goal and Rivers' 66-yard TD pass to Sproles.  However, Denver responded with a 12-play, 80-yard drive (which included a second controversial officiating call that turned a game-winning fumble into an incomplete pass) that concluded with Cutler completing a 4-yard TD pass to WR Eddie Royal, including Cutler's 2-point conversion pass to Royal. Notable: The game has been titled by press and websites as "The Mile High Highjacking" after the officiating call that cost San Diego the game.
[A]:
How many more field goal yards did Nate Kaeding make than Matt Prater?
