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.

[EX Q]: 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.
[EX A]: How many less tons of crude oil than Angola does Iran supply China?

[EX Q]: Passage: Hoping to continue their winning streak, the Bears flew to Cowboys Stadium for an NFC matchup with the Cowboys. In the first quarter Chicago took the early lead as kicker Robbie Gould nailed a 38-yard field goal. Then they trailed with WR Dez Bryant returning a punt 62 yards to the endzone for a touchdown. While the Cowboys were able to pressure quarterback Jay Cutler in the early stages of the game, the Bears' offense made adjustments and regained momentum.

The Bears increased their lead when kicker Robbie Gould made a 40-yard field goal. In the third quarter Dallas would reply with kicker David Buehler nailing a 28-yard field goal. The Bears increased their lead in the fourth quarter when Cutler made a three-yard TD pass to RB Matt Forte. The Cowboys made the final score of the game with Buehler hitting a 48-yard field goal.
[EX A]: How many field goals between 20 and 60 yards were made?

[EX Q]: Passage: The 2011 Thailand Country Report provides population numbers for mountain peoples (hill tribes) and ethnic communities in the Northeast and is explicit about its main reliance on the Mahidol University Ethnolinguistic Maps of Thailand data. Thus, though over 3.288 million people in the Northeast alone could not be categorised, the population and percentages of other ethnic communities circa 1997 are known for all of Thailand and constitute minimum populations. In descending order, the largest (equal to or greater than 400,000) are a) 15,080,000 Lao (24.9 percent) consisting of the Thai Lao (14 million) and other smaller Lao groups, namely the Thai Loei (400–500,000), Lao Lom (350,000), Lao Wiang/Klang (200,000), Lao Khrang (90,000), Lao Ngaew (30,000), and Lao Ti (10,000; b) six million Khon Muang (9.9 percent, also called Northern Thais); c) 4.5 million Pak Tai (7.5 percent, also called Southern Thais); d) 1.4 million Khmer Leu (2.3 percent, also called Northern Khmer); e) 900,000 Malay (1.5%); f) 500,000 Ngaw (0.8 percent); g) 470,000 Phu Thai (0.8 percent); h) 400,000 Kuy/Kuay (also known as Suay) (0.7 percent), and i) 350,000 Karen (0.6 percent). Thai Chinese, those of significant Chinese heritage, are 14% of the population, while Thais with partial Chinese ancestry comprise up to 40% of the population. Thai Malays represent 3% of the population, with the remainder consisting of Mon people, Khmers and various "Hill tribe (Thailand)". The countrys official language is Thai language and the primary religion is Theravada Buddhism, which is practised by around 95% of the population.
[EX A]:
How many more Lao Khrang were there compared to Lao Ngaew?
