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 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.
How many more total force was the South than the North?

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.

Passage: The Russian governments official 2014 military budget is about 2.49 trillion rubles (approximately US$69.3 billion), the List of countries by military expenditures in the world behind the US and China. The official budget is set to rise to 3.03 trillion rubles (approximately US$83.7 billion) in 2015, and 3.36 trillion rubles (approximately US$93.9 billion) in 2016. However, unofficial estimates put the budget significantly higher, for example the Stockholm International Peace Research Institute (SIPRI) 2013 Military Expenditure Database estimated Russias military expenditure in 2012 at US$90.749 billion. This estimate is an increase of more than US$18 billion on SIPRIs estimate of the Russian military budget for 2011 (US$71.9 billion). , Russias military budget is higher than any other European nation.

How many fewer US dollars was the Russian military budget in 2014 than it was be in 2015?
