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: A total of United States dollar50.1 billion (equivalent to $}} presently) was involved, or 11% of the total war expenditures of the U.S. In all, $31.4 billion (equivalent to $}} today) went to Britain and its Empire, $11.3 billion (equivalent to $}} today) to the Soviet Union, $3.2 billion (equivalent to $}} today) to France, $1.6 billion (equivalent to $}} today) to China, and the remaining $2.6 billion to the other Allies. Reverse lend-lease policies comprised services such as rent on bases used by the U.S., and totaled $7.8 billion; of this, $6.8 billion came from the British and the Commonwealth of Nations, mostly Australia and India. The terms of the agreement provided that the materiel was to be used until returned or destroyed. In practice very little equipment was in usable shape for peacetime uses. Supplies that arrived after the termination date were sold to Britain at a large discount for £1.075 billion, using long-term loans from the United States. Canada was not part of Lend Lease. However it operated a similar program called Billion Dollar Gift and Mutual Aid that sent a loan of $1 billion and $3.4 billion in supplies and services to Britain and other Allies.
Example Output: Did Canada send more in loans or supplies to Britain and other Allies?

Example Input: Passage: In 1966, the Korean People's Army  deployed eight infantry divisions along the DMZ, backed by eight more infantry divisions, three motorized infantry divisions, a tank division and a collection of separate infantry and tank brigades and regiments. Its total armed forced personnel numbered 386,000. While strong, this conventional force was smaller than the South's ground forces of about 585,000, and it was unlikely that the North could deliver a knockout blow before the U.S. could deploy additional forces. The main unconventional warfare arm was the Reconnaissance Bureau of the Ministry of Defense under the operational control of the Liaison Department of the Worker's Party of Korea which included the 17th Foot Reconnaissance Brigade and the all-officer Unit 124 and 283rd Army Units. These units were all highly trained and indoctrinated, skilled in demolitions and small-unit tactics, they would usually operate in small teams of 2-12 men, lightly armed with either PPS submachine guns or AK-47s. The Reconnaissance Bureau also controlled the 23d Amphibious Brigade, which used specially made infiltration boats to operate along the South Korean coastline. The Reconnaissance Bureau could also use conventional KPA and Korean People's Navy forces to support the infiltration and exfiltration of its teams. In addition to the offensive irregular forces, North Korea also deployed several thousand operator-agitators to select, train, and supervise informants and guerrilla recruits, while others attempted to cause individual defections and unit dissatisfaction in the ROK military and generally undermine the morale of both the ROKs and the Americans.
Example Output: How many more total force was the South than the North?

Example Input: Passage: In 2007-2008, Sun posted revenue of $13.8 billion and had $2 billion in cash. First-quarter 2008 losses were $1.68 billion; revenue fell 7% to $12.99 billion. Suns stock lost 80% of its value November 2007 to November 2008, reducing the companys market value to $3 billion. With falling sales to large corporate clients, Sun announced plans to lay off 5,000 to 6,000 workers, or 15-18% of its work force. It expected to save $700 million to $800 million a year as a result of the moves, while also taking up to $600 million in charges.
Example Output:
How many billion did Sun's revenue fall by in the first quarter of 2008?
