Question: How much of the continent on which the region that shares a border with Champagne-Ardenne is located is covered by the Alps?

full_context: Document 1: Rhine: Until the early 1980s, industry was a major source of water pollution. Although many plants and factories can be found along the Rhine up into Switzerland, it is along the Lower Rhine that the bulk of them are concentrated, as the river passes the major cities of Cologne, Düsseldorf and Duisburg. Duisburg is the home of Europe's largest inland port and functions as a hub to the sea ports of Rotterdam, Antwerp and Amsterdam. The Ruhr, which joins the Rhine in Duisburg, is nowadays a clean river, thanks to a combination of stricter environmental controls, a transition from heavy industry to light industry and cleanup measures, such as the reforestation of Slag and brownfields. The Ruhr currently provides the region with drinking water. It contributes 70 m3/s (2,500 cu ft/s) to the Rhine. Other rivers in the Ruhr Area, above all, the Emscher, still carry a considerable degree of pollution.
Document 2: Ardennes: The trees and rivers of the Ardennes provided the charcoal industry assets that enabled the great industrial period of Wallonia in the 18th and 19th centuries, when it was arguably the second great industrial region of the world, after England. The greater region maintained an industrial eminence into the 20th century, after coal replaced charcoal in metallurgy.
Document 3: 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 4: Institute of technology: In addition, France's education system includes many institutes of technology, embedded within most French universities. They are referred-to as institut universitaire de technologie (IUT). Instituts universitaires de technologie provide undergraduate technology curricula. 'Polytech institutes', embedded as a part of eleven French universities provide both undergraduate and graduate engineering curricula.
Document 5: Southern California: The Tech Coast is a moniker that has gained use as a descriptor for the region's diversified technology and industrial base as well as its multitude of prestigious and world-renowned research universities and other public and private institutions. Amongst these include 5 University of California campuses (Irvine, Los Angeles, Riverside, Santa Barbara, and San Diego); 12 California State University campuses (Bakersfield, Channel Islands, Dominguez Hills, Fullerton, Los Angeles, Long Beach, Northridge, Pomona, San Bernardino, San Diego, San Marcos, and San Luis Obispo); and private institutions such as the California Institute of Technology, Chapman University, the Claremont Colleges (Claremont McKenna College, Harvey Mudd College, Pitzer College, Pomona College, and Scripps College), Loma Linda University, Loyola Marymount University, Occidental College, Pepperdine University, University of Redlands, University of San Diego, and the University of Southern California.
Document 6: Alps: The population of the region is 14 million spread across eight countries. On the rim of the mountains, on the plateaus and the plains the economy consists of manufacturing and service jobs whereas in the higher altitudes and in the mountains farming is still essential to the economy. Farming and forestry continue to be mainstays of Alpine culture, industries that provide for export to the cities and maintain the mountain ecology.
Document 7: Alps: The Alps provide lowland Europe with drinking water, irrigation, and hydroelectric power. Although the area is only about 11 percent of the surface area of Europe, the Alps provide up to 90 percent of water to lowland Europe, particularly to arid areas and during the summer months. Cities such as Milan depend on 80 percent of water from Alpine runoff. Water from the rivers is used in over 500 hydroelectricity power plants, generating as much as 2900 kilowatts of electricity.
Document 8: Science and technology in Wallonia: Science and technology in Wallonia, the southern region of Belgium (Europe), is well developed with the presence of several universities and research institutes.
Document 9: Alps: Major European rivers flow from Switzerland, such as the Rhine, the Rhone, the Inn, the Ticino and the Po, all of which have headwaters in the Alps and flow into neighbouring countries, finally emptying into the North Sea, the Mediterranean Sea, the Adriatic Sea and the Black Sea. Other rivers such as the Danube have major tributaries flowing into them that originate in the Alps. The Rhone is second to the Nile as a freshwater source to the Mediterranean Sea; the river begins as glacial meltwater, flows into Lake Geneva, and from there to France where one of its uses is to cool nuclear power plants. The Rhine originates in a 30 square kilometre area in Switzerland and represents almost 60 percent of water exported from the country. Tributary valleys, some of which are complicated, channel water to the main valleys which can experience flooding during the snow melt season when rapid runoff causes debris torrents and swollen rivers.
Document 10: Switzerland: Switzerland lies between latitudes 45° and 48° N, and longitudes 5° and 11° E. It contains three basic topographical areas: the Swiss Alps to the south, the Swiss Plateau or Central Plateau, and the Jura mountains on the west. The Alps are a high mountain range running across the central-south of the country, comprising about 60% of the country's total area. The majority of the Swiss population live in the Swiss Plateau. Among the high valleys of the Swiss Alps many glaciers are found, totalling an area of 1,063 square kilometres (410 sq mi). From these originate the headwaters of several major rivers, such as the Rhine, Inn, Ticino and Rhône, which flow in the four cardinal directions into the whole of Europe. The hydrographic network includes several of the largest bodies of freshwater in Central and Western Europe, among which are included Lake Geneva (also called le Lac Léman in French), Lake Constance (known as Bodensee in German) and Lake Maggiore. Switzerland has more than 1500 lakes, and contains 6% of Europe's stock of fresh water. Lakes and glaciers cover about 6% of the national territory. The largest lake is Lake Geneva, in western Switzerland shared with France. The Rhône is both the main source and outflow of Lake Geneva. Lake Constance is the second largest Swiss lake and, like the Lake Geneva, an intermediate step by the Rhine at the border to Austria and Germany. While the Rhône flows into the Mediterranean Sea at the French Camarque region and the Rhine flows into the North Sea at Rotterdam in the Netherlands, about 1000 km apart, both springs are only about 22 km apart from each other in the Swiss Alps.
Document 11: Jacques-Cartier River: Logging in the Laurentian highlands became an important economic activity during the second half of the 18th century. The Jacques-Cartier River was used for log drives to transport the logs to the Saint-Lawrence River and to the mills downstream. This practice was only stopped in 1975. With the settlement of French immigrants near the river's mouth came the formation of townships (modelled after English townships after their conquest of 1759) and new industries appeared such as flour mills.
Document 12: Institute of technology: Hogeschool is used in Belgium and in the Netherlands. The hogeschool has many similarities to the Fachhochschule in the German language areas and to the ammattikorkeakoulu in Finland.
Document 13: 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. Additionally, there is a small group of German speakers, numbering around one percent, who live in the East Cantons. The capital and largest city is Brussels; other major cities are Antwerp, Ghent, Charleroi and Liège.
Document 14: Alps: High levels of precipitation cause the glaciers to descend to permafrost levels in some areas whereas in other, more arid regions, glaciers remain above about the 3,500 m (11,483 ft) level. The 1,817 square kilometres (702 sq mi) of the Alps covered by glaciers in 1876 had shrunk to 1,342 km2 (518 sq mi) by 1973, resulting in decreased river run-off levels. Forty percent of the glaciation in Austria has disappeared since 1850, and 30% of that in Switzerland.
Document 15: Devil's Backbone State Forest: Although much of future state forest was too steep and the soil too thin for agriculture, it nonetheless was part of a growing Virginia economy. The first industry to use the forest was iron furnaces established in the mid-18th century and existing until after the Civil War. Isaac Zane, a Quaker from Pennsylvania, built the first two of these furnaces (Zane's Old Furnace 1768-74 and The Marlboro Works 1772-95) and received grants of forest land which included the future state forest to be used to make charcoal as fuel.
