Document 11: Belgium: Belgium was the first continental European country to undergo the Industrial Revolution, in the early 19th century. Liège and Charleroi rapidly developed mining and steelmaking, which flourished until the mid-20th century in the Sambre and Meuse valley and made Belgium among one of the three most industrialized nations in the world from 1830 to 1910. However, by the 1840s the textile industry of Flanders was in severe crisis, and the region experienced famine from 1846 to 1850.After World War II, Ghent and Antwerp experienced a rapid expansion of the chemical and petroleum industries. The 1973 and 1979 oil crises sent the economy into a recession; it was particularly prolonged in Wallonia, where the steel industry had become less competitive and experienced serious decline. In the 1980s and 1990s, the economic center of the country continued to shift northwards and is now concentrated in the populous Flemish Diamond area.By the end of the 1980s, Belgian macroeconomic policies had resulted in a cumulative government debt of about 120% of GDP. As of 2006, the budget was balanced and public debt was equal to 90.30% of GDP. In 2005 and 2006, real GDP growth rates of 1.5% and 3.0%, respectively, were slightly above the average for the Euro area. Unemployment rates of 8.4% in 2005 and 8.2% in 2006 were close to the area average. By October 2010, this had grown to 8.5% compared to an average rate of 9.6% for the European Union as a whole (EU 27). From 1832 until 2002, Belgium's currency was the Belgian franc. Belgium switched to the euro in 2002, with the first sets of euro coins being minted in 1999. The standard Belgian euro coins designated for circulation show the portrait of the monarch (first King Albert II, since 2013 King Philippe).
Document 12: Rhine: In the centre of Basel, the first major city in the course of the stream, is located the "Rhine knee"; this is a major bend, where the overall direction of the Rhine changes from West to North. Here the High Rhine ends. Legally, the Central Bridge is the boundary between High and Upper Rhine. The river now flows North as Upper Rhine through the Upper Rhine Plain, which is about 300 km long and up to 40 km wide. The most important tributaries in this area are the Ill below of Strasbourg, the Neckar in Mannheim and the Main across from Mainz. In Mainz, the Rhine leaves the Upper Rhine Valley and flows through the Mainz Basin.

Document 14: Belgium: Belgium, officially the Kingdom of Belgium, is a country in Western Europe bordered by France, the Netherlands, Germany and Luxembourg. A small and densely populated country, it covers an area of 30,528 square kilometres (11,787 sq mi) and has a population of more than 11 million. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch - speaking, mostly Flemish community, which constitutes about 59 percent of the population, and the French - speaking, mostly Walloon population, which comprises about 40 percent of all Belgians.

The capital and largest city is Brussels; other major cities are Antwerp, Ghent, Charleroi and Liège.
Document 15: Rhine: Near Tamins-Reichenau the Anterior Rhine and the Posterior Rhine join and form the Rhine. The river makes a distinctive turn to the north near Chur. This section is nearly 86 km long, and descends from a height of 599 m to 396 m. It flows through a wide glacial alpine valley known as the Rhine Valley (German: Rheintal). Near Sargans a natural dam, only a few metres high, prevents it from flowing into the open Seeztal valley and then through Lake Walen and Lake Zurich into the river Aare. The Alpine Rhine begins in the most western part of the Swiss canton of Graubünden, and later forms the border between Switzerland to the West and Liechtenstein and later Austria to the East.
