Input: Czech language
Czech continued to evolve and gain in regional importance for hundreds of years, and has been a literary language in the Slovak lands since the early fifteenth century. A biblical translation, the Kralice Bible, was published during the late sixteenth century (around the time of the King James and Luther versions) which was more linguistically conservative than either. The publication of the Kralice Bible spawned widespread nationalism, and in 1615 the government of Bohemia ruled that only Czech-speaking residents would be allowed to become full citizens or inherit goods or land. This, and the conversion of the Czech upper classes from the Habsburg Empire's Catholicism to Protestantism, angered the Habsburgs and helped trigger the Thirty Years' War (where the Czechs were defeated at the Battle of White Mountain). The Czechs became serfs; Bohemia's printing industry (and its linguistic and political rights) were dismembered, removing official regulation and support from its language. German quickly became the dominant language in Bohemia.

How many years as Czech continued to evolve and gain in regional importance?
Output: hundreds

Input: Green
The late nineteenth century also brought the systematic study of color theory, and particularly the study of how complementary colors such as red and green reinforced each other when they were placed next to each other. These studies were avidly followed by artists such as Vincent van Gogh. Describing his painting, The Night Cafe, to his brother Theo in 1888, Van Gogh wrote: "I sought to express with red and green the terrible human passions. The hall is blood red and pale yellow, with a green billiard table in the center, and four lamps of lemon yellow, with rays of orange and green. Everywhere it is a battle and antithesis of the most different reds and greens."

When did the systematic study of color theory begin?
Output: late nineteenth century

Input: Nanjing
The city of Nanjing was razed after the Sui dynasty took over it. It renamed Shengzhou (昇州) in Tang dynasty and resuscitated during the late Tang. It was chosen as the capital and called Jinling (金陵) during the Southern Tang (937–976), a state that succeeded Wu state. It renamed Jiangning (江寧) in Northern Song dynasty and renamed Jiankang in Southern Song dynasty. Jiankang's textile industry burgeoned and thrived during the Song dynasty despite the constant threat of foreign invasions from the north by the Jurchen-led Jin dynasty. The court of Da Chu, a short-lived puppet state established by the Jurchens, and the court of Song were once in the city. Song was eventually exterminated by the Mongol empire under the name Yuan and in Yuan dynasty the city's status as a hub of the textile industry was further consolidated.

During what dynasty did Nanjing become a thriving textile city?
Output:
the Song dynasty
