instruction:
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.
question:
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.
answer:
How many years after Tsewang Rabtan invaded Tibet did the Battle of the Salween River take place?

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.
answer:
How long was the longest field goal?

question:
Passage: In 1967, local authorities were empowered to provide family planning advice to any who requested it and to provide supplies free of charge. In addition, medical training was expanded following the Todd Report on medical education in 1968. In addition, National Health expenditure rose from 4.2% of GNP in 1964 to 5% in 1969 and spending on hospital construction doubled. The Health Services and Public Health Act 1968 empowered local authorities to maintain workshops for the elderly either directly or via the agency of a voluntary body. A Health Advisory Service was later established to investigate and confront the problems of long-term psychiatric and mentally subnormal hospitals in the wave of Ely Hospital. The Family Planning Act 1967 empowered local authorities to set up a family planning service with free advice and means-tested provision of contraceptive devices while the Clean Air Act 1968 extended powers to combat air pollution. More money was also allocated to hospitals treating the mentally ill. In addition, a Sports Council was set up to improve facilities. Direct government expenditure on sports more than doubled from 0.9 million in 1964/65 to 2 million in 1967/68, while 11 regional Sports Councils had been set up by 1968. In Wales, five new health centres had been opened by 1968, whereas none had been opened from 1951 to 1964, while spending on health and welfare services in the region went up from 55.8 million in 1963/64 to 83.9 million in 1967/68.
answer:
What was passed first, The Family Planning Act or Clean Air Act?
