Extract the answer to the question from the following context. Question: What phenomenon was Thuringia experiencing from 2008 to 2012? Context: Migration plays an important role in Thuringia. The internal migration shows a strong tendency from rural areas towards the big cities. From 2008 to 2012, there was a net migration from Thuringia to Erfurt of +6,700 persons (33 per 1000 inhabitants), +1,800 to Gera (19 per 1000), +1,400 to Jena (14 per 1000), +1,400 to Eisenach (33 per 1000) and +1,300 to Weimar (21 per 1000). Between Thuringia and the other German states, the balance is negative: In 2012, Thuringia lost 6,500 persons to other federal states, the most to Bavaria, Saxony, Hesse and Berlin. Only with Saxony-Anhalt and Brandenburg the balance is positive. The international migration is fluctuating heavily. In 2009, the balance was +700, in 2010 +1,800, in 2011 +2,700 and in 2012 +4,800. The most important countries of origin of the Thuringia migrants from 2008 to 2012 were Poland (+1,700), Romania (+1,200), Afghanistan (+1,100) and Serbia/Montenegro/Kosovo (+1,000), whereas the balance was negative with Switzerland (2,800) and Austria (900).
Ans: internal migration

Extract the answer to the question from the following context. Question: Who did the Supreme Court decide was not responsible to solve the segregation problem? Context: On August 18, 1970, the NAACP filed suit against Michigan state officials, including Governor William Milliken, charging de facto public school segregation. The NAACP argued that although schools were not legally segregated, the city of Detroit and its surrounding counties had enacted policies to maintain racial segregation in public schools. The NAACP also suggested a direct relationship between unfair housing practices and educational segregation, which followed segregated neighborhoods. The District Court held all levels of government accountable for the segregation in its ruling. The Sixth Circuit Court affirmed some of the decision, holding that it was the state's responsibility to integrate across the segregated metropolitan area. The U.S. Supreme Court took up the case February 27, 1974. The subsequent Milliken v. Bradley decision had wide national influence. In a narrow decision, the Court found that schools were a subject of local control and that suburbs could not be forced to solve problems in the city's school district.
Ans: suburbs

Extract the answer to the question from the following context. Question: How are borough leaders appointed? Context: For administrative purposes, the Federal District is divided into 16 "delegaciones" or boroughs. While not fully equivalent to a municipality, the 16 boroughs have gained significant autonomy, and since 2000 their heads of government are elected directly by plurality (they were previously appointed by the head of government of the Federal District). Given that Mexico City is organized entirely as a Federal District, most of the city services are provided or organized by the Government of the Federal District and not by the boroughs themselves, while in the constituent states these services would be provided by the municipalities. The 16 boroughs of the Federal District with their 2010 populations are:
Ans: directly by plurality

Extract the answer to the question from the following context. Question: Which countries arose after the political boundaries of West Asia were redrawn? Context: Ultimately, World War I created a decisive break with the old world order that had emerged after the Napoleonic Wars, which was modified by the mid-19th century's nationalistic revolutions. The results of World War I would be important factors in the development of World War II approximately 20 years later. More immediate to the time, the partitioning of the Ottoman Empire was a political event that redrew the political boundaries of West Asia. The huge conglomeration of territories and peoples formerly ruled by the Sultan of the Ottoman Empire was divided into several new nations. The partitioning brought the creation of the modern Arab world and the Republic of Turkey. The League of Nations granted France mandates over Syria and Lebanon and granted the United Kingdom mandates over Mesopotamia and Palestine (which was later divided into two regions: Palestine and Transjordan). Parts of the Ottoman Empire on the Arabian Peninsula became parts of what are today Saudi Arabia and Yemen.
Ans: modern Arab world and the Republic of Turkey
