Problem: The Bronx has also become home to a peculiar poetic tribute, in the form of the Heinrich Heine Memorial, better known as the Lorelei Fountain from one of Heine's best-known works (1838). After Heine's German birthplace of Dusseldorf had rejected, allegedly for anti-Semitic motives, a centennial monument to the radical German-Jewish poet (17971856), his incensed German-American admirers, including Carl Schurz, started a movement to place one instead in Midtown Manhattan, at Fifth Avenue and 59th Street. However, this intention was thwarted by a combination of ethnic antagonism, aesthetic controversy and political struggles over the institutional control of public art.
Where was Heinrich Heine born?
The answer is the following: Dusseldorf

Problem: Despite the Dutch presence in Indonesia for almost 350 years, as the Asian bulk of the Dutch East Indies, the Dutch language has no official status there and the small minority that can speak the language fluently are either educated members of the oldest generation, or employed in the legal profession, as some legal codes are still only available in Dutch. Dutch is taught in various educational centres in Indonesia, the most important of which is the Erasmus Language Centre (ETC) in Jakarta. Each year, some 1,500 to 2,000 students take Dutch courses there. In total, several thousand Indonesians study Dutch as a foreign language. Owing to centuries of Dutch rule in Indonesia, many old documents are written in Dutch. Many universities therefore include Dutch as a source language, mainly for law and history students. In Indonesia this involves about 35,000 students.
For how long have there been Dutch speakers in Indonesia?
The answer is the following: almost 350 years

Problem: With the extension of Turkish dominion into the Balkans, the strategic conquest of Constantinople became a crucial objective. The empire had managed to control nearly all former Byzantine lands surrounding the city, but in 1402 the Byzantines were temporarily relieved when the Turco-Mongol leader Timur, founder of the Timurid Empire, invaded Anatolia from the east. In the Battle of Ankara in 1402, Timur defeated the Ottoman forces and took Sultan Bayezid I as a prisoner, throwing the empire into disorder. The ensuing civil war lasted from 1402 to 1413 as Bayezid's sons fought over succession. It ended when Mehmed I emerged as the sultan and restored Ottoman power, bringing an end to the Interregnum, also known as the Fetret Devri.
What battle between Timur and the Ottoman empire took place in 1402?
The answer is the following:
Battle of Ankara
