TASK DEFINITION: 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.
PROBLEM: Passage: In 1642, Gushi 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 Polhane Sonam Topgye 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.

SOLUTION: How many years after Tsewang Rabtan invaded Tibet did the Battle of the Salween River take place?

PROBLEM: Passage: Just days after teammate Sean Taylor died of his injuries, the Redskins tried to snap a three-game skid at home against the Buffalo Bills. Before the kickoff, the stadium held a memorial service for Sean Taylor, as well as players across the NFL wearing a #21 sticker on the back of their helmets. For the team's first defensive play, they would come out with only 10 players on the field, as their honor to Taylor. In the first quarter, the Redskins took the early lead as kicker Shaun Suisham managed to get a 27-yard field goal for the only score of the quarter. In the second quarter, the Redskins increased their lead as Suisham kicked a 28-yard field goal. Later, the Bills got on the board as linebacker Angelo Crowell sacked quarterback Jason Campbell in his end zone for a safety. The Redskins would end the half as Suisham kicked a 33-yard field goal. In the third quarter, the Bills drew closer as kicker Rian Lindell managed to get a 38-yard field goal. Later, the Redskins responded with running back Clinton Portis getting a 3-yard touchdown run. Afterwards, the Bills ended the half as Lindell kicked a 43-yard field goal. In the fourth quarter, the Bills drew closer as Lindell kicked a 24-yarder, along with a 33-yard field goal. Later, the Bills got into position to kick a 51-yard field goal. They got the kick, but Head Coach Joe Gibbs called timeout. When the Bills tried to kick again, Gibbs called timeout again, but unintentionally got his team an unsportsmanlike conduct penalty which not only moved the Bills 15 yards closer to their end zone but reduced Lindell's field goal attempt to 36 yards. Afterwards, the Bills ended the game with Lindell nailing the game-winning 36-yard field goal.

SOLUTION: How long was the longest field goal?

PROBLEM: Passage: The southeast corner of Siberia south of the Stanovoy Range was twice contested between Russia and China. Hydrologically, the Stanovoy Range separate the rivers that flow north into the Arctic from those that flow south into the Amur River. Ecologically, the area is the southeastern edge of the Siberian boreal forest with some areas good for agriculture. Socially and politically, from about 600 AD, it was the northern fringe of the Chinese-Manchu world. Various Chinese dynasties would claim sovereignty, build forts and collect tribute when they were strong enough. The Ming dynasty Nurgan Regional Military Commission built a fort on the Northern bank of the Amur at Aigun, and established an administrative seat at Telin, modern Tyr, Russia above Nikolaevsk-on-Amur. Russian expansion into Siberia began with the conquest of the Khanate of Sibir in 1582. By 1643 they reached the Pacific at Okhotsk. East of the Yenisei River there was little land fit for agriculture, except Dauria, the land between the Stanovoy Range and the Amur River which was nominally subject to the Qing dynasty. In 1643, Russian adventurers spilled over the Stanovoy Range, but by 1689 they were driven back by the Qing. The land was populated by some 9,000 Daurs on the Zeya River, 14,000 Duchers downstream and several thousand Tungus and Nivkhs toward the river mouth. The first Russians to hear of Dauria were probably Ivan Moskvitin and Maxim Perfilev about 1640. In 1859/60 the area was annexed by Russia and quickly filled up with a Russian population.

SOLUTION:
How many more Duchers populated the Zeya river than Daurs?
