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.

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.
How many airships did the United States Navy (USN) hope to use the V-1710 in?

Passage: The Cowboys opened the season at home against their rival, the New York Giants, led by the quarterback-receiver tandem of Eli Manning and young Odell Beckham Jr.. Tony Romo came back late in the fourth quarter and nailed the game-winning drive to Jason Witten to give Dallas a narrow 27-26 victory. The victory, however, was bittersweet as Dez Bryant broke his foot in the second half. The injury required surgery and he is expected to miss 10-12 weeks. Cameras caught Bryant congratulating his teammates in the locker room after a close victory. Romo on Bryant injury: "You can't replace Dez Bryant." Three days after, the NFL came forward and apologized to the New York Giants for 2 blown calls. The first call led to a Cowboy touchdown due to a wrong Pass Interference call which set up the Cowboys 1st and Goal on the 2 yard line and the second was a blown Defensive Holding call which would have set up the Giants first and Goal with the Cowboys having no Time Outs remaining and 1:36 left on the clock.
How many points did the Cowboys win by?

Passage: Trying to end a four-game losing skid, the Buccaneers flew to Cleveland Browns Stadium for a Week 16 interconference fight with the Cleveland Browns on Christmas Eve. In the first half, the Bucs got off to a decent start with kicker Matt Bryant nailing a 23-yard field goal in the first quarter and a 24-yard field goal in the second quarter. In the third quarter, Tampa Bay increased its lead RB Michael Pittman's 11-yard TD run (following PAT was blocked). In the fourth quarter, the Pewter Pirates' defense got a chance to score with OLB Derrick Brooks returning an interception 21 yards for a touchdown. Afterwards, the Browns would get their only score of the game as CB Daven Holly returned a fumble 40 yards for a touchdown. After that, the Bucs wrapped the game up with Bryant's 37-yard field goal. With the win, the Buccaneers improved to 4-11.
