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.

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.
How many less tons of crude oil than Angola does Iran supply China?

Passage: Democrat Bill Clinton carried the county in 1992 and it has remained reliably Red states and blue states in every election since. In the nationally close United States presidential election in New Jersey, 2000, Democrat Al Gore won the county decisively with 59.9% of the vote to Republican George W. Bushs 36.1%, a Democratic victory margin of 23.7%, while winning the state overall by a 56-40 margin. In the United States presidential election in New Jersey, 2004, many of the suburban counties surrounding New York City, including Middlesex County, swung Republican in response to the 9/11 terrorist attacks, but Democrat John Kerry still carried the county comfortably by a 13.6% margin over George W. Bush, Kerry taking 56.3% of the vote to Bushs 42.8%, while Kerry carried the state overall by 6.7% over Bush.  In United States presidential election in New Jersey, 2008, Barack Obama carried Middlesex County by a much larger 21.8% margin over John McCain, Obama taking 60.2% of the vote to McCains 38.4%, while Obama won New Jersey overall by 15.5% over McCain. In United States presidential election in New Jersey, 2012, Obama won an even more commanding victory in the county, receiving 63.2% of the vote to Republican Mitt Romneys 35.6%, a Democratic victory margin of 27.6%, while carrying New Jersey overall by 17.8%. Like much of the New York City metro area, Middlesex County was one of the few parts of the country to actually swing even harder in Obamas favor in 2012 compared to 2008, even as he lost ground nationally, indicating a long-term trend toward Democratic dominance in Middlesex County.
How many percentage points did Al Gore win over George W. Bush in the county in 2000?

Passage: After a scoreless first quarter, the Cardinals struck first on a Jay Feely 47-yard field goal. The Lions responded with a 72-yard touchdown pass from Matthew Stafford to Calvin Johnson, to take a 7-3 lead. The Cardinals went up 10-7 on a 36-yard TD pass from Carson Palmer to Andre Ellington.  The Lions retook the lead, 14-10, when Stafford and Johnson connected again, this time on a 3-yard TD pass. Arizona scored first in the third quarter, capitalizing on a Lions turnover with a 23-yard Jay Feely field goal. The Lions got a turnover of their own, as DeAndre Levy returned an interception 66 yards for a touchdown, making the score 21-13. The Cardinals finished the third quarter scoring with a 43-yard Feely field goal to close the score to 21-16. Feely hit again from 33 yards early in the fourth quarter to make the score 21-19. A pass interference penalty by Bill Bentley put the ball on the Lions 1-yard line late in the final quarter, and Arizona's Rashard Mendenhall plunged over two plays later for a touchdown. Arizona failed on a 2-point conversion, making the final score Cardinals 25, Lions 21. Matthew Stafford was 24-of-36 passing for 278 yards and two touchdowns. Calvin Johnson led all receivers with 6 receptions for 116 yards and two touchdowns.  David Akers missed a 47-yard field goal, and had another field goal attempt blocked.
