Question: When did women get to vote in the country Fränzi Aufdenblatten's birthplace and Wengen is located?

full_context: Document 1: Switzerland: Switzerland joined the Council of Europe in 1963. In 1979 areas from the canton of Bern attained independence from the Bernese, forming the new canton of Jura. On 18 April 1999 the Swiss population and the cantons voted in favour of a completely revised federal constitution.In 2002 Switzerland became a full member of the United Nations, leaving the Vatican City as the last widely recognised state without full UN membership. Switzerland is a founding member of the EFTA, but is not a member of the European Economic Area. An application for membership in the European Union was sent in May 1992, but not advanced since the EEA was rejected in December 1992 when Switzerland was the only country to launch a referendum on the EEA. There have since been several referendums on the EU issue; due to opposition from the citizens, the membership application has been withdrawn. Nonetheless, Swiss law is gradually being adjusted to conform with that of the EU, and the government has signed a number of bilateral agreements with the European Union. Switzerland, together with Liechtenstein, has been completely surrounded by the EU since Austria's entry in 1995. On 5 June 2005, Swiss voters agreed by a 55% majority to join the Schengen treaty, a result that was regarded by EU commentators as a sign of support by Switzerland, a country that is traditionally perceived as independent and reluctant to enter supranational bodies.
Document 2: Fränzi Aufdenblatten: Born in Zermatt, Valais, Aufdenblatten made her World Cup debut in March 2000 in a giant slalom at Sestriere. She scored four podium finishes on the World Cup: one win in a super-G in Val-d'Isère in December 2009, and three third places in downhill at Haus im Ennstal (2004), Bad Kleinkirchheim (2006), and Lenzerheide (2014). Aufdenblatten competed in three Winter Olympics (2002, 2006 and 2014) and her best finish was a sixth place in the 2014 super-G at Rosa Khutor.
Document 3: 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 4: 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 5: Women's suffrage in the United States: The Women's suffrage in the United States of America, the legal right of women to vote, was established over the course of several decades, first in various states and localities, sometimes on a limited basis, and then nationally in 1920.
Document 6: Switzerland: Many Swiss also follow ice hockey and support one of the 12 clubs in the League A, which is the most attended league in Europe. In 2009, Switzerland hosted the IIHF World Championship for the 10th time. It also became World Vice-Champion in 2013. The numerous lakes make Switzerland an attractive place for sailing. The largest, Lake Geneva, is the home of the sailing team Alinghi which was the first European team to win the America's Cup in 2003 and which successfully defended the title in 2007. Tennis has become an increasingly popular sport, and Swiss players such as Martina Hingis, Roger Federer, and most recently, Stanislas Wawrinka have won multiple Grand Slams. Swiss professional wrestler Claudio Castagnoli is currently signed with WWE, and is a former United States champion.
Document 7: 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.
Document 8: 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 9: 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 10: Women's suffrage: Most independent countries enacted women's suffrage in the interwar era, including Canada in 1917, Britain (over 30 in 1918, over 21 in 1928), Germany, Poland in 1918, Austria and the Netherlands in 1919, and the United States in 1920 (Voting Rights Act of 1965 secured voting rights for racial minorities). Leslie Hume argues that the First World War changed the popular mood:
Document 11: 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 12: Switzerland: Direct democracy and federalism are hallmarks of the Swiss political system. Swiss citizens are subject to three legal jurisdictions: the commune, canton and federal levels. The 1848 federal constitution defines a system of direct democracy (sometimes called half-direct or representative direct democracy because it is aided by the more commonplace institutions of a representative democracy). The instruments of this system at the federal level, known as civic rights (Volksrechte, droits civiques), include the right to submit a constitutional initiative and a referendum, both of which may overturn parliamentary decisions.
Document 13: Women's suffrage in Switzerland: Women in Switzerland gained the right to vote in federal elections after a referendum in February 1971. In 1991 following a decision by the Federal Supreme Court of Switzerland, Appenzell Innerrhoden became the last Swiss canton to grant women the vote on local issues.
Document 14: 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 15: 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.
