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 Browns hosted the Pittsburgh Steelers, who were coming off a loss against the Cowboys. The Steelers defeated the Browns 24-9, dropping the Browns to 0-11. With the loss, the Browns were mathematically eliminated from postseason contention for the 14th consecutive season. For the second consecutive season, they were the first NFL team to be mathematically eliminated from contention. The Browns have now gone 24 consecutive seasons without winning a division title, extending the longest active streak in the NFL. They also extended their current franchise record for most consecutive games lost to 14 games. The team is also the first team to start 0-11 since the 2011 Indianapolis Colts.

Answer: How many points did the Browns lose by?


Question: Passage: Hoping to rebound from their loss to the Eagles, the Panthers flew to the Georgia Dome for a Week 2 NFC South duel with the Atlanta Falcons.  In the first quarter, Carolina delivered the first scratch as kicker John Kasay got a 38-yard field goal.

The Panthers would retake the lead in the second quarter as running back DeAngelo Williams getting a 3-yard touchdown run, but Atlanta would reply with Ryan completing a 10-yard touchdown pass to running back Jason Snelling.  Carolina would gain some ground as Kasay nailed a 50-yard field goal, but the Falcons would close out the half with Ryan completing a 7-yard touchdown pass to wide receiver Roddy White.  After a scoreless third quarter, Atlanta would pull away as running back Michael Turner getting a 1-yard touchdown.  The Panthers would try to rally, but get only get an 11-yard touchdown pass from quarterback Jake Delhomme to tight end Dante Rosario.
