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.

Question: 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.".

Answer: How many combined chemical deaths did both the British and Russian have together?


Question: Passage: The Dano-Hanseatic War from 1426-1435  was an armed trade conflict between the Danish dominated Kalmar Union  and the German Hanseatic League  led by the Free City of Lübeck. When Danish king Eric opened the Baltic trade routes for Dutch ships and introduced a new toll for all foreign ships passing the Øresund , six Hanseatic cities  declared war, put a naval blockade on Scandinavian harbours and allied with Eric's enemy Henry IV, count of Holstein. Therefore the war was intensively linked with the Dutch-Hanseatic War , the Kalmar War with Holstein  and the Swedish revolt . After years of changing fortune in warfare Rostock and Stralsund signed a separate peace agreement in 1430. Lübeck, Hamburg, Wismar and Lüneburg, however, continued the war and assisted Holstein to conquer Flensburg in 1431. Thereafter they agreed an armistice in 1432 and started peace negotiations. Meanwhile an anti-Danish revolt broke out in Sweden . In 1434 Eric had to agree an armistice with the Swedes, too. In April 1435 he signed the peace of Vordingborg with the Hanseatic League and Holstein, followed by the peace of Stockholm with Sweden a few months later the same year. The Hanseatic cities were excepted from the Sound Dues but they had to accept Dutch competition in the Baltic trade. The Danish Duchy of Schleswig was ceded to the count of Holstein. Sweden's autonomous rights and privileges were extended. These peace agreements weakened Eric's position dramatically, and in 1439 he got dethroned by Danish, Swedish and Norwegian Privy Councils.

Answer: Around how many months do these events span?


Question: Passage: From the Great Recession, Czech Republic is in stagnation or decreasing of GDP. Some commenters and economists criticising fiscally conservative policy of Petr Nečas right-wing government, especially criticising ex-minister of finance, Miroslav Kalousek. Miroslav Kalousek in a 2008 interview, as minister of finance in the center-right government of Mirek Topolánek, said "Czech Republic will not suffer by financial crisis".

From 2009 to 2012, Czech Republic suffered highest state budget deficits in history of independent Czech Republic. From 2008 to 2012, the public debt of Czech Republic increased by 18,9%. Most decrease of industrial output was in construction industry (-25% in 2009, -15,5% in 2013). From 4Q 2009 to 1Q 2013, GDP decreased by 7,8%.

Answer:
