Question: How did a federal union rank the economy of the country where Ulrich Inderbinen died?

full_context: Document 1: Matterhorn: The Matterhorn (German: Matterhorn, (ˈmatərˌhɔrn); Italian: Cervino, (ˈtʃerˈviːno); French: Le Cervin, (mɔ̃ sɛʁvɛ̃)) is a mountain of the Alps, straddling the main watershed and border between Switzerland and Italy. It is a large, near - symmetrical pyramidal peak in the extended Monte Rosa area of the Pennine Alps, whose summit is 4,478 metres (14,692 ft) high, making it one of the highest summits in the Alps and Europe. The four steep faces, rising above the surrounding glaciers, face the four compass points and are split by the Hörnli, Furggen, Leone, and Zmutt ridges. The mountain overlooks the Swiss town of Zermatt, in the canton of Valais, to the north - east and the Italian town of Breuil - Cervinia in the Aosta Valley to the south. Just east of the Matterhorn is Theodul Pass, the main passage between the two valleys on its north and south sides, and a trade route since the Roman Era.
Document 2: Ulrich Inderbinen: Ulrich Inderbinen (December 3, 1900, Zermatt, Valais – June 14, 2004) was a Swiss mountain guide famous for his longevity and love for mountain climbing. He had been on the top of Matterhorn over 370 times and made his last ascent of it when he was 90. Though he was not the first to summit the Matterhorn, he may have done it the best. His fame laid not in conquering mountains but safely guiding visitors to the top.
Document 3: Walter Bonatti: Walter Bonatti (; 22 June 1930 in Bergamo – 13 September 2011 in Rome) was an Italian mountain climber, explorer and journalist. He was noted for his many climbing achievements, including a solo climb of a new route on the south-west pillar of the Aiguille du Dru in August 1955, the first ascent of Gasherbrum IV in 1958 and in 1965 the first solo climb in winter of the North face of the Matterhorn on the mountain's centenary year of its first ascent. Immediately after his extraordinary solo climb on the Matterhorn Bonatti announced his retirement from professional climbing at the age of 35 and after 17 years of climbing activity. He authored many mountaineering books and spent the remainder of his career travelling off the beaten track as a reporter for the Italian magazine "Epoca".
Document 4: Federalism: Federalism in the United States is the evolving relationship between state governments and the federal government of the United States. American government has evolved from a system of dual federalism to one of associative federalism. In "Federalist No. 46," James Madison asserted that the states and national government "are in fact but different agents and trustees of the people, constituted with different powers." Alexander Hamilton, writing in "Federalist No. 28," suggested that both levels of government would exercise authority to the citizens' benefit: "If their [the peoples'] rights are invaded by either, they can make use of the other as the instrument of redress."

Document 5: Politics of the United States: The United States is a federal republic in which the president, Congress, and federal courts share powers reserved to the national government according to its Constitution. At the same time, the federal government shares sovereignty with the state governments.
Document 6: Alps: The lower regions and larger towns of the Alps are well-served by motorways and main roads, but higher mountain passes and byroads, which are amongst the highest in Europe, can be treacherous even in summer due to steep slopes. Many passes are closed in winter. A multitude of airports around the Alps (and some within), as well as long-distance rail links from all neighbouring countries, afford large numbers of travellers easy access from abroad.
Document 7: Alps: Some high mountain villages, such as Avoriaz (in France), Wengen, and Zermatt (in Switzerland) are accessible only by cable car or cog-rail trains, and are car free. Other villages in the Alps are considering becoming car free zones or limiting the number of cars for reasons of sustainability of the fragile Alpine terrain.
Document 8: Heinrich Harrer: Heinrich Harrer (; 6 July 1912 – 7 January 2006) was an Austrian mountaineer, sportsman, geographer, and author. He is best known for being on the four-man climbing team that made the first ascent of the North Face of the Eiger in Switzerland, and for his books "Seven Years in Tibet" (1952) and "The White Spider" (1959).
Document 9: Federalism: In contrast, Europe has a greater history of unitary states than North America, thus European "federalism" argues for a weaker central government, relative to a unitary state. The modern American usage of the word is much closer to the European sense. As the power of the Federal government has increased, some people have perceived a much more unitary state than they believe the Founding Fathers intended. Most people politically advocating "federalism" in the United States argue in favor of limiting the powers of the federal government, especially the judiciary (see Federalist Society, New Federalism).
Document 10: Federalism: Until recently, in the absence of prior agreement on a clear and precise definition, the concept was thought to mean (as a shorthand) 'a division of sovereignty between two levels of government'. New research, however, argues that this cannot be correct, as dividing sovereignty - when this concept is properly understood in its core meaning of the final and absolute source of political authority in a political community - is not possible. The descent of the United States into Civil War in the mid-nineteenth century, over disputes about unallocated competences concerning slavery and ultimately the right of secession, showed this. One or other level of government could be sovereign to decide such matters, but not both simultaneously. Therefore, it is now suggested that federalism is more appropriately conceived as 'a division of the powers flowing from sovereignty between two levels of government'. What differentiates the concept from other multi-level political forms is the characteristic of equality of standing between the two levels of government established. This clarified definition opens the way to identifying two distinct federal forms, where before only one was known, based upon whether sovereignty resides in the whole (in one people) or in the parts (in many peoples): the federal state (or federation) and the federal union of states (or federal union), respectively. Leading examples of the federal state include the United States, Germany, Canada, Switzerland, Australia and India. The leading example of the federal union of states is the European Union.
Document 11: Switzerland: Switzerland has an overwhelmingly private sector economy and low tax rates by Western World standards; overall taxation is one of the smallest of developed countries. Switzerland is a relatively easy place to do business, currently ranking 20th of 189 countries in the Ease of Doing Business Index. The slow growth Switzerland experienced in the 1990s and the early 2000s has brought greater support for economic reforms and harmonization with the European Union. According to Credit Suisse, only about 37% of residents own their own homes, one of the lowest rates of home ownership in Europe. Housing and food price levels were 171% and 145% of the EU-25 index in 2007, compared to 113% and 104% in Germany.
Document 12: Switzerland: The World Economic Forum's Global Competitiveness Report currently ranks Switzerland's economy as the most competitive in the world, while ranked by the European Union as Europe's most innovative country. For much of the 20th century, Switzerland was the wealthiest country in Europe by a considerable margin (by GDP – per capita). In 2007 the gross median household income in Switzerland was an estimated 137,094 USD at Purchasing power parity while the median income was 95,824 USD. Switzerland also has one of the world's largest account balances as a percentage of GDP.
Document 13: Economy of Switzerland: The economy of Switzerland is one of the world's most stable economies. The service sector has also come to play a significant economic role, particularly the Swiss banking industry and tourism. The economy of Switzerland ranks first in the world in the 2015 Global Innovation Index and the 2017 Global Competitiveness Report. According to United Nations data for 2016, Switzerland is the third richest landlocked country in the world after Liechtenstein and Luxembourg, and together with Norway the only two countries in the world with a GDP per capita above US $70,000 that are neither island nations nor ministates.
Document 14: Alps: The region is serviced by 4,200 km (2,600 mi) of roads used by 6 million vehicles. Train travel is well established in the Alps, with, for instance 120 km (75 mi) of track for every 1,000 km2 (390 sq mi) in a country such as Switzerland. Most of Europe's highest railways are located there. Moreover, plans are underway to build a 57 km (35 mi)-long sub-alpine tunnel connecting the older Lötschberg and Gotthard tunnels built in the 19th century.
Document 15: Switzerland: Switzerland is one of the richest and wealthiest countries in the world. Switzerland ranks top or close to the top in several metrics of national performance, including government transparency, civil liberties, quality of life, economic competitiveness, and human development. It has the highest nominal wealth (financial and non-financial assets) per adult in the world according to Credit Suisse and the eighth-highest per capita gross domestic product on the IMF list. Zürich and Geneva have each been ranked among the top cities with the highest quality of life in the world, with the former ranked 2nd globally, according to Mercer.
