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.

Example Input: Passage: In 2007, Kuwait supplied China with of oil per day, accounting for 2.6% of Chinas total crude oil imports. Saudi Arabia was Chinas top supplier with its shipments jumping 69.8 percent to 3.84 million tons (939,000 bbl/d), followed by Angola with 2.06 million tons (503,000 bbl/d), down 27.1 percent. Iran became third, with imports from the country shrinking 35.3 percent to 1.18 million tons (289,000 bbl/d). China is the worlds second-biggest oil consumer after the US. Abdullatif Al-Houti, Managing Director of International Marketing at state-run Kuwait Petroleum Corporation (KPC), told KUNA in October that Kuwait is on course for its China-bound crude oil export target of by 2015, but success will heavily depend on the Sino-Kuwaiti refinery project. The two countries have been in talks for the planned refinery in Chinas southern Guangdong Province. The complex is expected to be on-stream by 2020.
Example Output: How many less tons of crude oil than Angola does Iran supply China?

Example Input: Passage: In early 1858, Simpson was ordered to join the Army's reinforcements for the Utah War. He and his team resurveyed the trails from Fort Leavenworth to Utah and his photographer, Samuel C. Mills, produced the earliest surviving photographs of features along the trail. Upon his arrival at Camp Floyd, he was directed to open a new road between that post and Fort Bridger. Simpson and his team also surveyed the military reservation at Fort Bridger, at Camp Floyd and in the Rush Valley. In May 1859, he headed an expedition to survey a new route from Camp Floyd across the Great Salt Lake Desert of Utah and through the Great Basin to Genoa, Nevada near California. The Army contracted Frederick Lander to immediately to develop the more direct route to California for use by wagons, and Simpson's survey was later published in 1876. Simpson's Central Route played a vital role in the transportation of mail, freight, and passengers between the established eastern states and California, especially when hostilities of the Civil War closed the Butterfield Overland Mail stagecoach route that ran along the southern border states. George Chorpenning immediately switched to Simpson's route to run his existing mail and stage line, and the Pony Express used it as well. In 1861 the Transcontinental Telegraph was laid along the route, making the Pony Express obsolete. Afterwards, Wells Fargo & Co. hauled mail, freight, and passengers along Simpson's route until 1869, when transportation and telegraphy were switched to the newly completed Transcontinental Railroad.
Example Output: How many persons mentioned in that passage?

Example Input: Passage: Point guard Jason Terry became the teams scoring leader during the 200001 season, leading them with 19.7 ppg. After the All-Star break, the Hawks traded Mutombo to the Philadelphia 76ers for Theo Ratliff, Toni Kukoc, and Nazr Mohammed. However, Ratliff was injured and did not play with the Hawks until next season. They ended the season with a 2557 record. In 2001, the Hawks drafted Spanish star Pau Gasol 3rd, but his rights were ceded to the Memphis Grizzlies in a trade involving Shareef Abdur-Rahim. Abdur-Rahim became the teams scoring leader, and made his only All-Star appearance in 2002. The team ended up 3349 for the 200102 season. The Hawks sent Kukoc to the Milwaukee Bucks for All-Star Glenn Robinson in 2002, Robinson lead the team with 20.8 ppg. But the Hawks still failed to make the playoffs for the 200203 season, finishing with a 3547 record.
Example Output:
How many more games did the Hawks lose than win in the 2000-01 season?
