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: In 1642, Güshi Khan, founder of the Khoshut Khanate, overthrew the prince of Tsang and made the 5th Dalai Lama the highest spiritual and political authority in Tibet, establishing the regime known as Ganden Phodrang. Tsewang Rabtan invaded Tibet in 1717, deposed the pretender to the position of Dalai Lama of Lha-bzang Khan, the last ruler of the Khoshut Khanate, and killed Lha-bzang Khan and his entire family. They also viciously destroyed a small force in the Battle of the Salween River which the Kangxi Emperor of the Qing dynasty had sent to clear traditional trade routes in 1718. In response, an expedition sent by Kangxi Emperor, together with Tibetan forces under Polhané Sönam Topgyé of Tsang and Kangchennas , the governor of Western Tibet, expelled the Dzungars from Tibet in 1720. This began the Qing rule of Tibet, which lasted until the fall of the Qing dynasty in 1912.
[A]: How many years after Tsewang Rabtan invaded Tibet did the Battle of the Salween River take place?
