Question: What ranking was granted by the European Union to Otto Furrer's birth country?

full_context: Document 1: Alps: In the first half of the 20th century the Olympic Winter Games were held three times in Alpine venues: the 1924 Winter Olympics in Chamonix, France; the 1928 Winter Olympics in St. Moritz, Switzerland; and the 1936 Winter Olympics in Garmisch-Partenkirchen, Germany. During World War II the winter games were canceled but after that time the Winter Games have been held in St. Moritz (1948), Cortina d'Ampezzo (1956), Innsbruck, Austria (1964 and 1976), Grenoble, France, (1968), Albertville, France, (1992), and Torino (2006). In 1930 the Lauberhorn Rennen (Lauberhorn Race), was run for the first time on the Lauberhorn above Wengen; the equally demanding Hahnenkamm was first run in the same year in Kitzbühl, Austria. Both races continue to be held each January on successive weekends. The Lauberhorn is the more strenuous downhill race at 4.5 km (2.8 mi) and poses danger to racers who reach 130 km/h (81 mph) within seconds of leaving the start gate.
Document 2: 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 3: 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 4: 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 5: Alps: At present the Alps are one of the more popular tourist destinations in the world with many resorts such Oberstdorf, in Bavaria, Saalbach in Austria, Davos in Switzerland, Chamonix in France, and Cortina d'Ampezzo in Italy recording more than a million annual visitors. With over 120 million visitors a year tourism is integral to the Alpine economy with much it coming from winter sports although summer visitors are an important component of the tourism industry.
Document 6: 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 7: Netherlands: The Netherlands has a developed economy and has been playing a special role in the European economy for many centuries. Since the 16th century, shipping, fishing, agriculture, trade, and banking have been leading sectors of the Dutch economy. The Netherlands has a high level of economic freedom. The Netherlands is one of the top countries in the Global Enabling Trade Report (2nd in 2016), and was ranked the fifth most competitive economy in the world by the Swiss International Institute for Management Development in 2017. In addition, the country was ranked the second most innovative nation in the world in the 2018 Global Innovation Index.
Document 8: 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 9: Alps: During the post-World War I period ski-lifts were built in Swiss and Austrian towns to accommodate winter visitors, but summer tourism continued to be important; by the mid-20th century the popularity of downhill skiing increased greatly as it became more accessible and in the 1970s several new villages were built in France devoted almost exclusively to skiing, such as Les Menuires. Until this point Austria and Switzerland had been the traditional and more popular destinations for winter sports, but by the end of the 20th century and into the early 21st century, France, Italy and the Tyrol began to see increases in winter visitors. From 1980 to the present, ski-lifts have been modernized and snow-making machines installed at many resorts, leading to concerns regarding the loss of traditional Alpine culture and questions regarding sustainable development as the winter ski industry continues to develop quickly and the number of summer tourists decline.
Document 10: FIS Alpine World Ski Championships 1932: The FIS Alpine World Ski Championships 1932 were held 4–6 February in Cortina d'Ampezzo, Italy. These were the second world championships and the combined event was added to the program. The first edition was held the prior year in Mürren, Switzerland.
Document 11: Wolfgang Junginger: Wolfgang Junginger (27 October 1951 – 17 February 1982) was a German alpine skier who competed in the 1976 Winter Olympics. There he finished on 6th place in Special Slalom and on 4th place in Alpine Combined. Two years before, in World Championships at St. Moritz (Switzerland), he won the bronze medal in Alpine Combined. Mr. Junginger died in an airplane crash when he piloted a small airplane from Munich to Hannover in Germany. Including the pilot himself there were four persons in the plane and one of them was Mr. Ulrich Hoeness, well known manager of Bayern Munich. Mr. Hoeness was the only one who had survived the accident.
Document 12: Otto Furrer: Furrer was born in Zermatt. He became a world champion in the combined event, received a silver medal in the slalom and a bronze medal in the downhill in Cortina d'Ampezzo in 1932. He was killed in an accident on the Matterhorn.
Document 13: 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.
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: Franz Klammer: Franz Klammer (born 3 December 1953) is a former champion alpine ski racer from Austria. Klammer overwhelmingly dominated the downhill event for four consecutive World Cup seasons (1975-78). He was the gold medalist at the 1976 Winter Olympics in Innsbruck, winning the downhill at Patscherkofel by a margin of 0.33 seconds with a time of 1:45.73. He won 25 World Cup downhills, including four on the Hahnenkamm at Kitzbühel. He holds the record for the most victories (four) on the full course at Kitzbühel.
