instruction:
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.
question:
Passage: On 17 January 2011, it was announced that Motörhead would be part of the Sonisphere Festival in Knebworth. In August 2011, they headlined the Brutal Assault open-air festival in the Czech Republic. On 2 March 2011 Motörhead performed on Late Night with Jimmy Fallon. On 9 July 2011, former guitarist Würzel died of a heart attack. In celebration of 35 years touring, in late 2011 the band released the live DVD The Wörld Is Ours - Vol 1 - Everywhere Further Than Everyplace Else, including performances at the O2 Apollo Manchester, Best Buy Theater, New York City and Teatro Caupolicán, Santiago de Chile. On 19 December 2011, it was announced that Motörhead would play at the German festivals Rock am Ring and Rock im Park in Nürburgring and Nuremberg respectively in June 2012. On 12 January 2012, it was announced that Motörhead were touring the US and Canada in early 2012, along with three other metal bands Megadeth, Volbeat and Lacuna Coil. The Gigantour took place from 26 January to 28 February 2012, but Motörhead missed the final four shows because Lemmy had a combination of an upper respiratory viral infection and voice strain, resulting in severe laryngitis. Lemmy wrote on Facebook, "Im giving my voice a good rest", hoping he would recover soon to play at the Mayhem Festival, which was held from 30 June to 5 August 2012. Motörhead also took part on 23 June in the Rock-A-Field Luxembourg Open Air Festival in Roeser.
answer:
How many days did the Gigantour take place?


question:
Passage: Most of the fighting ended in continental North America in 1760, although it continued in Europe between France and Britain. The notable exception was the French seizure of St. John's, Newfoundland. General Amherst heard of this surprise action and immediately dispatched troops under his nephew William Amherst, who regained control of Newfoundland after the Battle of Signal Hill in September 1762. Many troops from North America were reassigned to participate in further British actions in the West Indies, including the capture of Spanish Havana when Spain belatedly entered the conflict on the side of France, and a British expedition against French Martinique in 1762 led by Major General Robert Monckton. General Amherst also oversaw the transition of French forts to British control in the western lands. The policies which he introduced in those lands disturbed large numbers of Indians and contributed to Pontiac's Rebellion in 1763. This series of attacks on frontier forts and settlements required the continued deployment of British troops, and it was not resolved until 1766.
answer:
How many countries continued to fight after the fighting ended in continental North America in 1760?


question:
Passage: Reunified Chinas Tang Dynasty (618-907) high culture set a high point for many things, including poetry. Various schools of Buddhism (a religion from India) flourished as represented by the Chinese Chán (or Zen) beliefs of Wang Wei (Tang dynasty) (701-761). His quatrains (jueju) describing natural scenes are world-famous examples of excellence, each couplet conventionally containing about two distinct images or thoughts per line. Tang poetrys big star is Li Bai (701-762) also pronounced and written as Li Bo, who worked in all major styles, both the more free old style verse (Gushi (poetry)) as well as the tonally regulated new style verse (Regulated verse). Regardless of genre, Tang poets notably strove to perfect a style in which poetic subjects are exposed and evident, often without directly referring to the emotional thrust at hand. The poet Du Fu (712-770) excelled at regulated verse and use of the seven-character line, writing denser poems with more allusions as he aged, experiencing hardship and writing about it. A parade of great Tang poets also includes Chen Ziang (661-702), Wang Zhihuan (688-742), Meng Haoran (689-740), Bai Juyi (772-846), Li He (790-816), Du Mu (803-852), Wen Tingyun (812-870), (listed chronologically) and Li Shangyin (813-858), whose poetry delights in allusions that often remain obscure, and whose emphasis on the seven-character line also contributed to the emerging posthumous fame of Du Fu, now ranked alongside Li Bai. The distinctively different Ci (poetry) poetry form began its development during the Tang as Central Asian and other musical influences flowed through its cosmopolitan society.
answer:

How many more years was Bai Juyi active than the poet who chronologically came after him?
