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

Passage: Hoping to rebound from their home loss to the Ravens, the Saints flew to Raymond James Stadium for an NFC South rematch with the Tampa Bay Buccaneers.  In the first quarter, quarterback Drew Brees completed a 15-yard touchdown pass to rookie WR Marques Colston and a 52-yard touchdown pass to WR Devery Henderson.  In the second quarter, kicker John Carney would complete a 46-yard field goal to give New Orleans a 17-0 lead.  Yet, the Bucs started to fight back, as quarterback Bruce Gradkowski completed two touchdown passes to WR Joey Galloway (a 44-yarder and a 17-yarder).  In the third quarter, the Saints would take over for the rest of the game, as RB Deuce McAllister completed a 3-yard touchdown run, while Brees completed a 45-yard touchdown pass to Henderson.  After a scoreless fourth quarter, New Orleans would get the sweep over Tampa Bay and improve to 6-2.

Ex Output:
How many more touchdown passes did Drew Brees make compared to Bruce Gradkowski?

Passage: The Broncos traveled to Gillette Stadium to play the New England Patriots during the Sunday night game on September 24. The game was a rematch of the divisional playoff game of the previous season in which the Broncos beat the Patriots and ended their record 10-game playoff winning streak.  The Broncos won 17-7, improving their record to 2-1.  The Broncos scored a 23-yard field goal (by kicker Jason Elam) and a touchdown in the second quarter (a 32-yard TD pass from QB Jake Plummer to Javon Walker). Plummer and Walker would hook up for another touchdown in the fourth quarter with an 83-yard touchdown pass. The Broncos held New England to only 50 yards on the ground, while Tatum Bell ran for 123 yards. The Patriots scored a touchdown in the fourth quarter when Tom Brady threw an 8-yard pass to Doug Gabriel. The Broncos became the first team since the 1942 Chicago Cardinals to begin their season with 11 straight quarters without allowing their opponents to score a touchdown.

Ex Output:

How long were each of Javon Walker's touchdown receptions?
