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 index reached a relative intraday highwhich was not exceeded for over seven yearsof 1,552.87, on March 24, 2000, during the dot-com bubble. The index then declined by approximately 50%, to 768.63, on October 10, 2002, during the stock market downturn of 2002. On May 30, 2007, the S&P 500 closed at 1,530.23, to set its first all-time closing high in more than seven years. Although the index achieved a new all-time intraday high on October 11, 2007, at 1,576.09, following a record close of 1,565.15 on October 9, the index finished 2007 at 1,468.36 pointsjust below its 1999 annual close. Less than a month later, it dropped to 1,400, and would not see similar levels again for five years.

Ex Output:
How many points had the index gained from October 10, 2002 to October 11, 2007?

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: The New York Giants tied an NFL record with twelve sacks as they dealt the Eagles a 16-3 loss. Philadelphia entered the game with five starters out due to injury, including running back Brian Westbrook. Penalties, sacks, and the absence of Westbrook stymied the offense, which scored 56 points last week, throughout the first three quarters. The Giants took the lead on a touchdown reception by Plaxico Burress in the second quarter. A botched handoff led to a defensive touchdown for Kawika Mitchell and a 16-0 New York lead. David Akers' 53-yard field goal in the fourth quarter allowed the Eagles to avoid a shutout. Osi Umenyiora had six of the Giants' sacks. Correll Buckhalter rushed for 103 yards in the defeat. The loss drops Philadelphia to 1-3, their worst start since 1999, as they entered their bye week.
