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.

[Q]: 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.
[A]: By how many points lower is Florence's brith rate than that of the Italian average?


[Q]: Passage: The Chargers came into this game with a 1-8 all-time record against Atlanta, and this marked San Diego's first visit to Atlanta since 2004. The Falcons had built a 27-10 lead by the two-minute warning at the end of the first half, but the Chargers pulled them back and leveled the score at 30-30 with a 33-yard Josh Lambo field goal with 18 seconds left in regulation. Lambo then hit a 42-yard attempt in overtime to seal the win for the Chargers as they improved to 3-4.
[A]: How many points ahead were the Falcons at the end of the first half?


[Q]: Passage: Hoping to snap a two-game losing streak, the Broncos remained on home ground for an AFC West duel against the Oakland Raiders. The Broncos grabbed the early lead, with quarterback Peyton Manning throwing a 22-yard touchdown pass to tight end Joel Dreessen. The Raiders responded, with a 38-yard field goal by placekicker Sebastian Janikowski, but the Broncos countered, with a 21-yard field goal by placekicker Matt Prater at the end of the first quarter. A 24-yard field goal by Janikowski just before halftime was the only scoring play of the second quarter. The Broncos' offense exploded in the third quarter, with Manning connecting on a 17-yard touchdown pass to wide receiver Eric Decker, followed by a 2-yard touchdown run by running back Willis McGahee and a 14-yard touchdown pass from Manning to running back Lance Ball. Prater added field goals of 43 and 53 yards in the fourth quarter. With the win, the Broncos snapped a four-game home losing streak against the Raiders. Center J. D. Walton suffered a dislocated ankle late in the second quarter, and was placed on the season-ending injured reserve the following day (October 1).
[A]:
How long was Manning longest touchdown pass?
