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: The first successful use of poison gas as a weapon of warfare occurred during the Second Battle of Ypres . Gas was soon used by all major belligerents throughout the war. It is estimated that the use of chemical weapons employed by both sides throughout the war had inflicted 1.3 million casualties. For example, the British had over 180,000 chemical weapons casualties during the war, and up to one-third of American casualties were caused by them. The Russian Army reportedly suffered roughly 500,000 chemical weapon casualties in World War I. The use of chemical weapons in warfare was in direct violation of the 1899 Hague Declaration Concerning Asphyxiating Gases and the 1907 Hague Convention on Land Warfare, which prohibited their use. The effect of poison gas was not limited to combatants. Civilians were at risk from the gases as winds blew the poison gases through their towns, and they rarely received warnings or alerts of potential danger. In addition to absent warning systems, civilians often did not have access to effective gas masks. An estimated 100,000-260,000 civilian casualties were caused by chemical weapons during the conflict and tens of thousands more  died from scarring of the lungs, skin damage, and cerebral damage in the years after the conflict ended. Many commanders on both sides knew such weapons would cause major harm to civilians but nonetheless continued to use them. British Field Marshal Sir Douglas Haig wrote in his diary, "My officers and I were aware that such weapons would cause harm to women and children living in nearby towns, as strong winds were common in the battlefront. However, because the weapon was to be directed against the enemy, none of us were overly concerned at all.".
[EX A]: How many combined chemical deaths did both the British and Russian have together?

[EX Q]: 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.
[EX A]: How many more total force was the South than the North?

[EX Q]: Passage: Over the remainder of Louis XIII's reign, and especially during the minority of Louis XIV, the implementation of the Edict varied year by year. In 1661 Louis XIV, who was particularly hostile to the Huguenots, started assuming control of his government and began to disregard some of the provisions of the Edict. In 1681 he instituted the policy of dragonnades, to intimidate Huguenot families to convert to Roman Catholicism or emigrate. Finally, in October 1685, Louis issued the Edict of Fontainebleau, which formally revoked the Edict and made the practice of Protestantism illegal in France. The revocation of the Edict had very damaging results for France. While it did not prompt renewed religious warfare, many Protestants chose to leave France rather than convert, with most moving to Great Britain, Prussia, the Dutch Republic and Switzerland. At the dawn of the 18th century, Protestants remained in significant numbers in the remote Cévennes region of the Massif Central. This population, known as the Camisards, revolted against the government in 1702, leading to fighting that continued intermittently until 1715, after which the Camisards were largely left in peace.
[EX A]:
Camisards, revolted against the government on and off for how many years.?
