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: In 1860s, the relations between Qatar and Bahrain deteriorated with a series of small disputes. Hostilities emerged when, in 1867, Bahrain arrested a Qatari Bedouin in the Qatari mainland and deported him to Bahrain. In response, the Qataris, led by the Naim tribe, defeated the Bahraini army that was based on the peninsula, effectively expelling them. These tensions led Bahrain, allied with Abu Dhabi, to attack Qatar. The conflict failed to pacify and resulted in an escalation between the two parties in the following year. In October 1867, the Bahraini Hakim Mohammed al Khalifa, sent his brother, Ali Al Khalifa, with a force of 500 men in 24 boats to attack Qatar. He was joined by a force of 200 men under Ahmed al Khalifa. Additionally, Bahrain's ally Abu Dhabi sent 2,000 troops in 70 boats. The attack on Qatar led to the sacking of Bida  and Wakra. A British record later stated "that the towns of Doha and Wakrah were, at the end of 1867 temporarily blotted out of existence, the houses being dismantled and the inhabitants deported". A Qatari counterattack followed the next year, resulting in the destruction of most of the Bahraini naval vessels deployed. The 1868 attack resulted in some 1,000 individuals killed and 60 ships destroyed.
[A]: How many men did Ali Al Khalifa have under his command?


[Q]: Passage: In 2000, the band played 47 songs. In 2002, they increased the set list to 59 songs. In 2004, 311 played 68 songs. The band played entire albums, rarities and covers. Later that year, a DVD was released of the performance that contained 64 of the 68 songs. 311 Day in 2006 was held at the Mid-South Coliseum in Memphis, Tennessee, where the band played 65 songs. The intended set list was cut short from 69 songs because of a strict midnight curfew.

In 2008, 311 Day was held in the New Orleans Arena in New Orleans, Louisiana. Over three separate sets, the band played 63 songs to a sold-out crowd of 14,000 fans, who represented all 50 states and 13 countries. In 2010, 311 Day took place at the Mandalay Bay Events Center in Las Vegas Valley. All 60 songs, 32 of which were different from 311 Day in 2008, were broadcast live on the web in a video on demand format described as a "professional multi-camera HD production." In 2012, 311 Day took place at the MGM Grand Garden Arena in Las Vegas and, for the first time, was split into two days. The band performed 79 songs during the two-day concert. On July 3, 2013, the band announced at the Unity Tour show in Chicago that 311 Day 2014 would be returning to New Orleans. 311 Day 2016 took place in New Orleans, at the Smoothie King Center (New Orleans Arena) on 3/11/2016 & 3/12/2016. 311 Day 2018 took place on 3/10 and 3/11 in Las Vegas at the Park Theatre at the Monte Carlo Resort & Casino. 86 songs were played, including a cover of Pink Floyds "Wish You Were Here" with a In Memoriam video tribute to late musicians and 311 fans Renee ONeal, Meredith Hight, and Nick Hexums youngest brother Patrick.
