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.

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.".

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

Q: Passage: In the second meeting of the year with the Washington Redskins, the Eagles tried an onside kick to start the game. This backfired when the Redskins running back Quinton Ganther recovered the kick and returned it 25 yards to the Eagles 24-yard line. Four plays later, Redskins quarterback Jason Campbell ran for a two-yard touchdown to score the game's first touchdown, as the Redskins took the lead 7-0. After a holding penalty on Eagles tight end Brent Celek, the Eagles had to settle for a 29-yard field goal by kicker David Akers. On the following drive by the Eagles, quarterback Donovan McNabb found wide receiver DeSean Jackson wide open in the end zone for a 35-yard touchdown to bring the Eagles up 10-7. On the ensuing drive by the Redskins, Campbell threw a 4-yard touchdown pass to Santana Moss to take the lead 14-10. Late in the second quarter, after both teams punting the ball away after three unsuccessful drives, Eagles cornerback Asante Samuel intercepted a Jason Campbell pass that was intended for Santana Moss. The Eagles could not convert a third down with 10 to go, and David Akers kicked a 24-yard field goal to get the Eagles within a point of the Redskins, 14-13. The Redskins received the ball again and Campbell threw a second straight interception to Samuel, who returned it for 17 yards. The Eagles ended the first half with a second straight field goal to take the lead 16-14. The Eagles got the ball to start the second half, but the drive ended with a Sav Rocca punt. Jason Campbell threw a 10-yard touchdown to tight end Fred Davis to take the lead once again, 21-16. After two straight punts for each team, the Eagles got the ball back in the fourth quarter and Donovan McNabb threw an intended pass to Reggie Brown, but the pass was intercepted by Redskins cornerback Justin Tryon. The Redskins scored on a 25-yard field goal by Shaun Suisham, to increase their lead 24-16. The Eagles started their drive on their own 10-yard line after a penalty on the kick return by Dimitri Patterson. The Eagles went 90 yards to score on an Eldra Buckley one-yard touchdown run. Since they were losing by two points, the Eagles decided to go for a two-point conversion. The two-point conversion was successful after rookie running back LeSean McCoy ran in the end zone on a shovel pass from McNabb. The score was tied, 24-24. The Redskins could not score on the next drive, and therefore had to punt to the Eagles. The Eagles scored on a 32-yard field goal by David Akers to take the lead, 27-24. The Eagles got the ball back on downs, and kneeled the ball to run out the clock and win 27-24.
