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: The population of the city proper is 370,702, while Eurostat estimates that 696,767 people live in the Larger Urban Zones of Florence. The Metropolitan Area of Florence, Prato and Pistoia, constituted in 2000 over an area of roughly , is home to 1.5 million people. Within Florence proper, 46.8% of the population was male in 2007 and 53.2% were female. Minors (children aged 18 and less) totalled 14.10 percent of the population compared to pensioners, who numbered 25.95 percent. This compares with the Italian average of 18.06 percent (minors) and 19.94 percent (pensioners). The average age of Florence resident is 49 compared to the Italian average of 42. In the five years between 2002 and 2007, the population of Florence grew by 3.22 percent, while Italy as a whole grew by 3.56 percent. The birth rate of Florence is 7.66 births per 1,000 inhabitants compared to the Italian average of 9.45 births.
Example Output: By how many points lower is Florence's brith rate than that of the Italian average?

Example Input: Passage: In order to regain control of the custom duties, the emperor John VI Kantakouzenos made preparations to lower Constantinople's duties and most tariffs to undercut the Genoese in Galata. Still recovering from the civil war of 1341-1347, the emperor, with great difficulty, raised 50,000 hyperpyra from private sources  for a shipbuilding program for the expected war to come. When the tariffs and custom duties were finally lowered, merchant shipping coming through the strait bypassed Genoese Galata and diverted their ships across the Golden Horn to Byzantine Constantinople. The Genoese, financially hard-hit from this policy, declared war on the Empire, and in August 1348, a flotilla of ships sailed across the Horn and attacked the Byzantine fleet; despite their large scale preparations, the Byzantine fleet was destroyed by early 1349. The Byzantines retaliated by burning wharves and warehouses along the shore and catapulted stones and burning bales of hay into Galata, setting major parts of the city on fire. After several weeks of fighting, plenipotentiaries from Genoa came and negotiated a peace agreement. The Genoese agreed to pay a war indemnity of 100,000 hyperpyra and evacuated the land behind Galata which they illegally occupied; last, they promised never to attack Constantinople. In return the Byzantines surrendered nothing, but the Genoese custom duties remained in effect.
Example Output: Approximately how many years did it take for the Byzantine fleet to be destroyed after August 1348?

Example Input: Passage: On 10 February 2016, qualifying for the sixth Copa del Rey final in the last eight seasons, Luis Enriques Barcelona broke the clubs record of 28 consecutive games unbeaten in all competitions set by Guardiolas team in the 2010–11 season, with a 1–1 draw with Valencia in the second leg of the 2015–16 Copa del Rey. With a 5–1 win at Rayo Vallecano on 3 March, Barcelonas 35th match unbeaten, the club broke Real Madrids Spanish record of 34 games unbeaten in all competitions from the 1988–1989 season. After Barça reached 39 matches unbeaten, their run ended on 2 April 2016 with a 2–1 defeat to Real Madrid at Camp Nou. On 14 May 2016, Barcelona won their sixth La Liga title in eight seasons. The front three of Messi, Suárez and Neymar finished the season with 131 goals, breaking the record they had set the previous year for most goals by an attacking trio in a single season. On 8 March 2017, Barcelona made the largest comeback in Champions League history in the 2016-17 UEFA Champions League in second Leg, Barcelona 6–1 Paris Saint-Germain (aggregate score 6–5), despite losing the first leg in France by a score of 4–0. On 29 May 2017, former player Ernesto Valverde was named as Luis Enriques successor signing a two-year contract with an option for a further year.
Example Output:
How many wins in a row did it take to beat Real Madrid's record?
