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.

Example Input: Passage: After a gradual 5-year recovery to an intraday high of 2,239.51 on October 31, 2007, the highest reached since February 16, 2001, the index corrected below the 2,000 level in early 2008 amid the Late-2000s recession, the United States housing bubble and the Financial crisis of 2007-2010. Panic focusing on the failure of the investment banking industry culminated in a loss of more than 10% on September 29, 2008, subsequently plunging the index firmly into bear market territory. The NASDAQ-100, with much of the broader market, experienced a Limit down open on October 24 and reached a 6-year intraday low of 1,018 on November 20, 2008.
Example Output: How many months passed between the index high and its 6-year intraday low?

Example Input: Passage: Trying to snap a four-game losing skid, the Broncos flew to the University of Phoenix Stadium for a Week 15 interconference fight with the Arizona Cardinals. The last time these two teams met each other, Denver won 37-7 at Invesco Field at Mile High on December 29, 2002. This time, it was a battle of rookie quarterbacks as Matt Leinart went up against Jay Cutler. In the first quarter, the Cardinals trailed early as Cutler completed a 54-yard TD pass to WR Javon Walker and kicker Jason Elam nailed a 30-yard field goal. In the second quarter, Arizona trailed even further with Elam's 22-yard field goal. The Cardinals would finally score as kicker Neil Rackers nailed a 49-yard field goal and DE Antonio Smith returned a fumble 4 yards for a touchdown. However, Denver managed to get one last field goal before halftime as Elam kicked a 30-yard field goal. In the third quarter, more struggles continued as Cutler completed a 10-yard TD pass to WR Rod Smith. Arizona would respond with Rackers kicking a 38-yard field goal. In the fourth quarter, the Broncos continued their pounding on the Cards with RB Mike Bell's 1-yard TD run. Even though the Cardinals got a 4-yard TD run by RB Edgerrin James, Denver wrapped up Cutler's first NFL win with another 1-yard TD run by Mike Bell. With the loss, Arizona fell to 4-10.
Example Output: From what yard line did the Cardinals score twice?

Example Input: Passage: Constantinople had been an imperial capital since its consecration in 330 under Roman Emperor, Constantine the Great. In the following eleven centuries, the city had been besieged many times but was captured only once: during the Fourth Crusade in 1204.:304 The crusaders established an unstable Latin state in and around Constantinople while the remaining empire splintered into a number of Byzantine successor states, notably Nicaea, Epirus and Trebizond. They fought as allies against the Latin establishments, but also fought among themselves for the Byzantine throne. The Nicaeans eventually reconquered Constantinople from the Latins in 1261. Thereafter, there was little peace for the much-weakened empire as it fended off successive attacks by the Latins, the Serbians, the Bulgarians, and, most importantly, the Ottoman Turks. The Black Plague between 1346 and 1349 killed almost half of the inhabitants of Constantinople. The city was severely depopulated due to the general economic and territorial decline of the empire, and by 1453 consisted of a series of walled villages separated by vast fields encircled by the fifth-century Theodosian walls. By 1450 the empire was exhausted and had shrunk to a few square miles outside the city of Constantinople itself, the Princes' Islands in the Sea of Marmara, and the Peloponnese with its cultural center at Mystras. The Empire of Trebizond, an independent successor state that formed in the aftermath of the Fourth Crusade, also survived on the coast of the Black Sea.
Example Output:
After the Nicaeans reconquered Constantinople, how many groups kept attacking Constantinople?
