Input: Zhejiang
Zhejiang, as the heartland of the Jiangnan (Yangtze River Delta), remained the wealthiest area during the Six Dynasties (220 or 222589), Sui, and Tang. After being incorporated into the Sui dynasty, its economic richness was used for the Sui dynasty's ambitions to expand north and south, particularly into Korea and Vietnam. The plan led the Sui dynasty to restore and expand the network which became the Grand Canal of China. The Canal regularly transported grains and resources from Zhejiang, through its metropolitan center Hangzhou (and its hinterland along both the Zhe River and the shores of Hangzhou Bay), and from Suzhou, and thence to the North China Plain. The debacle of the Korean war led to Sui's overthrow by the Tang, who then presided over a centuries-long golden age for the country. Zhejiang was an important economic center of the empire's Jiangnan East Circuit and was considered particularly prosperous. Throughout the Tang dynasty, The Grand Canal had remained effective, transporting grains and material resources to North China plain and metropolitan centers of the empire. As the Tang Dynasty disintegrated, Zhejiang constituted most of the territory of the regional kingdom of Wuyue.

What river was one of the Grand Canal of China's hinterlands?
Output: the Zhe River

Input: Queen (band)
In February 1981, Queen travelled to South America as part of The Game Tour, and became the first major rock band to play in Latin American stadiums. The tour included five shows in Argentina, one of which drew the largest single concert crowd in Argentine history with an audience of 300,000 in Buenos Aires and two concerts at the Morumbi Stadium in Sao Paulo, Brazil, where they played to an audience of more than 131,000 people in the first night (then the largest paying audience for a single band anywhere in the world) and more than 120,000 people the following night. In October of the same year, Queen performed for more than 150,000 fans on 9 October at Monterrey (Estadio Universitario) and 17 and 18 at Puebla (Estadio Zaragoza), Mexico. On 24 and 25 November, Queen played two sell out nights at the Montreal Forum, Quebec, Canada. One of Mercury's most notable performances of The Game's final track, "Save Me", took place in Montreal, and the concert is recorded in the live album, Queen Rock Montreal.

How large was Queen's record audience in Argentina?
Output: 300,000

Input: Botany
Increasing knowledge of plant anatomy, morphology and life cycles led to the realisation that there were more natural affinities between plants than the artificial sexual system of Linnaeus had indicated. Adanson (1763), de Jussieu (1789), and Candolle (1819) all proposed various alternative natural systems of classification that grouped plants using a wider range of shared characters and were widely followed. The Candollean system reflected his ideas of the progression of morphological complexity and the later classification by Bentham and Hooker, which was influential until the mid-19th century, was influenced by Candolle's approach. Darwin's publication of the Origin of Species in 1859 and his concept of common descent required modifications to the Candollean system to reflect evolutionary relationships as distinct from mere morphological similarity.

On what did Candolle base his classification system?
Output: morphological complexity

Input: Copyright infringement
Another example is the practice of compulsory licensing, which is where the law forbids copyright owners from denying a license for certain uses of certain kinds of works, such as compilations and live performances of music. Compulsory licensing laws generally say that for certain uses of certain works, no infringement occurs as long as a royalty, at a rate determined by law rather than private negotiation, is paid to the copyright owner or representative copyright collective. Some fair dealing laws, such as Canada's, include similar royalty requirements.

What country has fair dealing laws?
Output:
Canada
