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: Concerned by the Burmese consolidation of Shan states and Laotian states, China launched four invasions of Burma between 1765 and 1769. At first, the Qianlong Emperor envisaged an easy war, and sent in only the Green Standard troops stationed in Yunnan. The Qing invasion came as the majority of Burmese forces were deployed in their latest invasion of Siam. Nonetheless, battle-hardened Burmese troops defeated the first two invasions of 1765-1766 and 1766-1767 at the border. The regional conflict now escalated to a major war that involved military manoeuvres nationwide in both countries. The third invasion  led by the elite Manchu Bannermen nearly succeeded, penetrating deep into central Burma within a few days' march from Ava. But the Bannermen of northern China could not cope with unfamiliar tropical terrains and lethal endemic diseases, and were driven back with heavy losses. After the close-call, Hsinbyushin redeployed his armies from Siam to the Chinese front. The fourth and largest invasion got bogged down at the frontier. With the Qing forces completely encircled, a truce was reached between the field commanders of the two sides in December 1769.
[A]: After how many Chinese invasions did the conflict escalate from a regional conflict into a major war?


[Q]: Passage: The Bears entered week 15 of the NFL season hoping to secure a first-round bye and home-field advantage throughout the NFC playoffs. The Bears led 24-3 with 5:22 left in the third quarter and were en route to winning their third straight. During the first quarter, the Bucs had only reached 80 yards in total offense. Coach Jon Gruden sent in back-up Tim Rattay, who completed 20 of 35 for 268 yards with 3 touchdowns and one interception as the Bucs battled back to tie the game up at 31 during the fourth quarter. A controversial move was made by Chicago Bears' head coach Lovie Smith as he decided to let time expire during the fourth quarter and thus send the game into overtime. Tampa Bay won the coin toss, and both teams had three possessions in overtime. After missing earlier in the overtime period, Robbie Gould connected on a 27-yard field goal with 3:37 remaining to give the Bears the victory, 34-31. This loss sent the struggling Buccaneers to 3-11 which secured last place in the NFC South standings.
[A]: How many more points did the Bears have at the end than Tampa Bay?
