Problem: According to eastern homeland theory, prior to becoming known to the Roman world, Slavic-speaking tribes were part of the many multi-ethnic confederacies of Eurasia such as the Sarmatian, Hun and Gothic empires. The Slavs emerged from obscurity when the westward movement of Germans in the 5th and 6th centuries CE (thought to be in conjunction with the movement of peoples from Siberia and Eastern Europe: Huns, and later Avars and Bulgars) started the great migration of the Slavs, who settled the lands abandoned by Germanic tribes fleeing the Huns and their allies: westward into the country between the Oder and the Elbe-Saale line; southward into Bohemia, Moravia, much of present-day Austria, the Pannonian plain and the Balkans; and northward along the upper Dnieper river. Perhaps some Slavs migrated with the movement of the Vandals to Iberia and north Africa.
Who started the great migration of the Slavs?
The answer is the following: Germans

Located in the South Atlantic Ocean on the Mid-Atlantic Ridge, more than 2,000 kilometres (1,200 mi) from the nearest major landmass, Saint Helena is one of the most remote places in the world. The nearest port on the continent is Namibe in southern Angola, and the nearest international airport the Quatro de Fevereiro Airport of Angola's capital Luanda; connections to Cape Town in South Africa are used for most shipping needs, such as the mail boat that serves the island, the RMS St Helena. The island is associated with two other isolated islands in the southern Atlantic, also British territories: Ascension Island about 1,300 kilometres (810 mi) due northwest in more equatorial waters and Tristan da Cunha, which is well outside the tropics 2,430 kilometres (1,510 mi) to the south. The island is situated in the Western Hemisphere and has the same longitude as Cornwall in the United Kingdom. Despite its remote location, it is classified as being in West Africa by the United Nations.
What is the mail boat that serves the island called?
RMS St Helena

Input: Hellenistic period
Modern interpretations see this period as a civil war between Hellenized and orthodox forms of Judaism. Out of this revolt was formed an independent Jewish kingdom known as the Hasmonaean Dynasty, which lasted from 165 BCE to 63 BCE. The Hasmonean Dynasty eventually disintegrated in a civil war, which coincided with civil wars in Rome. The last Hasmonean ruler, Antigonus II Mattathias, was captured by Herod and executed in 37 BCE. In spite of originally being a revolt against Greek overlordship, the Hasmonean kingdom and also the Herodian kingdom which followed gradually became more and more hellenized. From 37 BCE to 6 CE, the Herodian dynasty, Jewish-Roman client kings, ruled Judea. Herod the Great considerably enlarged the Temple (see Herod's Temple), making it one of the largest religious structures in the world. The style of the enlarged temple and other Herodian architecture shows significant Hellenistic architectural influence.

When was Antigonus II Mattathias executed?
Output: 37 BCE

Input: Article: The most powerful used method works by comparing each frame in the video with the previous one. If the frame contains areas where nothing has moved, the system simply issues a short command that copies that part of the previous frame, bit-for-bit, into the next one. If sections of the frame move in a simple manner, the compressor emits a (slightly longer) command that tells the decompressor to shift, rotate, lighten, or darken the copy. This longer command still remains much shorter than intraframe compression. Interframe compression works well for programs that will simply be played back by the viewer, but can cause problems if the video sequence needs to be edited.

Now answer this question: What happens when a frame contains areas where nothing has moved?

Output: the system simply issues a short command

Article: Being a city on the Ill and close to the Rhine, Strasbourg has always been an important centre of fluvial navigation, as is attested by archeological findings. In 1682 the Canal de la Bruche was added to the river navigations, initially to provide transport for sandstone from quarries in the Vosges for use in the fortification of the city. That canal has since closed, but the subsequent Canal du Rhone au Rhine, Canal de la Marne au Rhin and Grand Canal d'Alsace are still in use, as is the important activity of the Port autonome de Strasbourg. Water tourism inside the city proper attracts hundreds of thousands of tourists yearly.

Question: What kind of tourism attracts tourists yearly?
Ans: Water tourism

Input: Boston
Boston has teams in the four major North American professional sports leagues plus Major League Soccer, and has won 36 championships in these leagues, As of 2014[update]. It is one of six cities (along with Chicago, Detroit, Los Angeles, New York and Philadelphia) to have won championships in all four major sports. It has been suggested that Boston is the new "TitleTown, USA", as the city's professional sports teams have won nine championships since 2001: Patriots (2001, 2003, 2004, and 2014), Red Sox (2004, 2007, and 2013), Celtics (2008), and Bruins (2011). This love of sports has made Boston the United States Olympic Committee's choice to bid to hold the 2024 Summer Olympic Games, but the city cited financial concerns when it withdrew its bid on July 27, 2015.

Why did the city turn down the chance to host the 2024 Olympic games?
Output:
financial concerns
