Input: Classical music
Burgh (2006), suggests that the roots of Western classical music ultimately lie in ancient Egyptian art music via cheironomy and the ancient Egyptian orchestra, which dates to 2695 BC. This was followed by early Christian liturgical music, which itself dates back to the Ancient Greeks[citation needed]. The development of individual tones and scales was made by ancient Greeks such as Aristoxenus and Pythagoras. Pythagoras created a tuning system and helped to codify musical notation. Ancient Greek instruments such as the aulos (a reed instrument) and the lyre (a stringed instrument similar to a small harp) eventually led to the modern-day instruments of a classical orchestra. The antecedent to the early period was the era of ancient music before the fall of the Roman Empire (476 AD). Very little music survives from this time, most of it from ancient Greece.

Which ancient society developed individual tones and scales?
Output: ancient Greeks

Input: New York City
In 1609, English explorer Henry Hudson re-discovered the region when he sailed his ship the Halve Maen ("Half Moon" in Dutch) into New York Harbor while searching for the Northwest Passage to the Orient for his employer, the Dutch East India Company. He proceeded to sail up what he named the North River, also called the Mauritis River, and now known as the Hudson River, to the site of the present-day New York State capital of Albany in the belief that it might represent an oceanic tributary. When the river narrowed and was no longer saline, he realized it was not a maritime passage and sailed back downriver. He made a ten-day exploration of the area and claimed the region for his employer. In 1614, the area between Cape Cod and Delaware Bay would be claimed by the Netherlands and called Nieuw-Nederland (New Netherland).

Who was Henry Hudson working for?
Output: Dutch East India Company

Input: Slavs
Throughout their history, Slavs came into contact with non-Slavic groups. In the postulated homeland region (present-day Ukraine), they had contacts with the Iranic Sarmatians and the Germanic Goths. After their subsequent spread, they began assimilating non-Slavic peoples. For example, in the Balkans, there were Paleo-Balkan peoples, such as Romanized and Hellenized (Jirecek Line) Illyrians, Thracians and Dacians, as well as Greeks and Celtic Scordisci. Over time, due to the larger number of Slavs, most descendants of the indigenous populations of the Balkans were Slavicized. The Thracians and Illyrians vanished from the population during this period although the modern Albanian nation claims descent from the Illyrians. Exceptions are Greece, where the lesser numbered Slavs scattered there came to be Hellenized (aided in time by more Greeks returning to Greece in the 9th century and the role of the church and administration) and Romania where Slavic people settled en route for present-day Greece, Republic of Macedonia, Bulgaria and East Thrace whereby the Slavic population had come to assimilate. Bulgars were also assimilated by local Slavs but their ruling status and subsequent land cast the nominal legacy of Bulgarian country and people onto all future generations. The Romance speakers within the fortified Dalmatian cities managed to retain their culture and language for a long time, as Dalmatian Romance was spoken until the high Middle Ages. However, they too were eventually assimilated into the body of Slavs.

Who vanished from the population of the Balkans?
Output: The Thracians and Illyrians

Input: Tajikistan
Russian border troops were stationed along the TajikAfghan border until summer 2005. Since the September 11, 2001 attacks, French troops have been stationed at the Dushanbe Airport in support of air operations of NATO's International Security Assistance Force in Afghanistan. United States Army and Marine Corps personnel periodically visit Tajikistan to conduct joint training missions of up to several weeks duration. The Government of India rebuilt the Ayni Air Base, a military airport located 15 km southwest of Dushanbe, at a cost of $70 million, completing the repairs in September 2010. It is now the main base of the Tajikistan air force. There have been talks with Russia concerning use of the Ayni facility, and Russia continues to maintain a large base on the outskirts of Dushanbe.

Why do US troops visit Tajikistan every so often?
Output:
to conduct joint training missions of up to several weeks duration.
