TASK DEFINITION: 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.
PROBLEM: Passage: The new Ottoman army arrived on the island during the winter of 1666/1667, and in May, the final phase of the siege, overseen by the Grand Vizier himself, began. It would last for 28 months and cost the lives of 70,000 Ottoman soldiers, 38,000 conscripted Cretans and slaves who labored in the Ottoman siege works and 29,088 of the city's Christian defenders. Faced with the renewed Ottoman assault and a struggling economy, despite the prospect of considerable reinforcements from Western Europe, in 1668 the Signoria hoped to end the war by striking a peace settlement with the Ottomans. Indeed, the Venetians hoped to use the imminent arrival of reinforcements to secure concessions from the Ottomans. Admiral Andrea Valier was at first appointed as envoy, but fell ill and was quickly replaced by the elderly nobleman Alvise da Molin. Molin and his embassy traveled to Larissa, where the Ottoman court resided during one of the Sultan's hunting expeditions. The Ottomans proposed that Venice keep one half of Crete, but the Signoria, emboldened by further pledges of reinforcements, especially from France, and renewed turmoil at the Ottoman court and within the Empire, refused the offer. Molin, in the meantime transported by the Ottomans to Canea in Crete, was ordered to continue negotiations and to continue observing the Ottomans' strength and intentions, but not commit himself or the Republic.

SOLUTION: How many more Ottoman soldiers died than conscripted Cretans?

PROBLEM: Passage: The Jets got the ball first and Pennington led the Jets on a 16-play, 83-yard drive that took 8:30 off the clock before Mike Nugent kicked a 27-yard field goal. On the Browns' next possession, Reuben Droughns had two big gains to put the Browns in position for Phil Dawson's 47-yard field goal, knotting the score, 3-3. Pennington was then intercepted by Sean Jones, and Charlie Frye led the Browns on a long drive that was capped by a 2-yard touchdown run by Droughns. Frye would get intercepted by Eric Smith on the Browns' next possession, but Nugent missed a 52-yard field goal wide right, his first missed field goal since Week 1. However, the Jets would get a break as Dawson missed a chip-shot 26-yard field goal at the end of the first half. Still, Cleveland led 10-3 at halftime. Cleveland got the ball first in the second half, and Droughns continued to move the ball, picking up solid yardage before Frye found Kellen Winslow II open on a 30-yard touchdown reception. After the teams traded punts, Leon Washington fumbled on the Jets' 10-yard line, with Nick Eason forcing and Kamerion Wimbley recovering. Dawson knocked in a 21-yard field goal to give Cleveland a 20-3 lead with 3:51 left in the third quarter. The Jets got an immediate lift when Justin Miller returned the ensuing kickoff 99 yards for a score, his second return of the year, to cut the lead to ten. After a Browns punt, Pennington drove the Jets into position for Nugent's 47-yard field goal to narrow the deficit to 20-13. But on the Jets' next possession, Pennington was again intercepted by Jones, but Cleveland was forced to punt. After another trade of punts, the Jets took over on Cleveland's 47-yard line with 1:56 to play. On 4th-and-4 from the Cleveland 24 with 1:06 to play, Pennington lofted a pass that Chris Baker leapt for and caught with one hand as he began to land. Just before his foot hit the ground, the Browns' Brodney Pool levelled Baker, who landed out-of-bounds but still in possession of the ball. The referee ruled that Baker was out-of-bounds, rather than ruling he was forced out, which would have led to a touchdown. Eric Mangini called a timeout in the hopes that the referees would review the play, but since it was a judgement call, it was non-reviewable under NFL rules. Frye took a knee to end the game.

SOLUTION: How many field goal attempts were missed in the game?

PROBLEM: Passage: During the civil war, and the ensuing Soviet–Afghan War, most of the countrys infrastructure was destroyed, and normal patterns of economic activity were disrupted. The gross national product (GNP) fell substantially during Karmals rule because of the conflict; trade and transport were disrupted along with the loss of labor and capital. In 1981 the Afghan GDP stood at 154.3 billion Afghan afghanis, a drop from 159,7 billion in 1978. GNP per capita decreased from 7,370 in 1978 to 6,852 in 1981. The most dominant form of economic activity was the Agriculture in Afghanistan. Agriculture accounted for 63 percent of gross domestic product (GDP) in 1981; 56 percent of the labour force worked in agriculture in 1982. Industry accounted for 21 percent of GDP in 1982, and employed 10 percent of the labour force. All industrial enterprises were government-owned. The service sector, the smallest of the three, accounted for 10 percent of GDP in 1981, and employed an estimated one-third of the labour force. The balance of payments, which had improved in the pre-communist administration of Muhammad Daoud Khan; the surplus decreased and became a deficit by 1982, which reached minus $US70.3 million. The only economic activity that grew substantially during Karmals rule was export and import.

SOLUTION:
Between 1978 and 1981, how many billion Afghan afghanis did the GDP drop?
