Please answer a question about the following article about Switzerland:

Straddling the intersection of Germanic and Romance Europe, Switzerland comprises four main linguistic and cultural regions: German, French, Italian and Romansh. Therefore, the Swiss, although predominantly German-speaking, do not form a nation in the sense of a common ethnicity or language; rather, Switzerland's strong sense of identity and community is founded on a common historical background, shared values such as federalism and direct democracy, and Alpine symbolism. Due to its linguistic diversity, Switzerland is known by a variety of native names: Schweiz [ˈʃvaɪts] (German);[note 5] Suisse [sɥis(ə)] (French); Svizzera [ˈzvittsera] (Italian); and Svizra [ˈʒviːtsrɐ] or [ˈʒviːtsʁːɐ] (Romansh).[note 6]
