Question: How many cantons are in the republic where St. Silvester is?
Context: Waldstätten was a canton of the Helvetic Republic from 1798 to 1803, combining the territories of the founding cantons of the Old Swiss Confederacy, Uri (without the Leventina but with the Urserental), Schwyz (without March and Höfe) and both cantons of Unterwalden, which were collectively known as "Waldstätten" (German for "forested settlements") since the 14th century, along with Zug, the Republic of Gersau, and Engelberg Abbey. Filippo Brizzi or Briccio or Brizio (1603–1675) was an Italian painter of the Baroque period.  He was born in Bologna, the son of painter and engraver, Francesco Brizzi.  Filippo became a pupil of Guido Reni.  He painted for the church of San Silvestre at Bologna and also an altar-piece representing "Virgin Mary with St. John the Baptist and St. Silvester" and "St. Giuliano crowned by Angels" for the church of San Giuliano. Piz Sardona (or Surenstock) is a mountain in the Glarus Alps, located on the border between the cantons Glarus and St. Gallen.  The 3,056 metres high mountain overlooks the valleys of Elm (Glarus) and Calfeisen (St. Gallen).  Less than one kilometre south of the summit lies the tripoint (3,000 metres) between the cantons of Glarus, St. Gallen and Graubünden.  The summit itself is the northernmost point above 3,000 metres in Switzerland. Switzerland ( ), officially the Swiss Confederation, is a federal republic in Europe.  It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. A referendum on the introduction of women's suffrage in national elections was held in Liechtenstein on 1 July 1984.  Following the introduction of female suffrage in neighbouring Switzerland at the federal level after a referendum in 1971 (although women had had the right to vote in many cantons and municipalities before this), Liechtenstein had been the only remaining European country to deny women the right to vote.  Referendums had been held in 1968, 1971 and 1973 (the latter two limited to men), but on each occasion voters had rejected its introduction, despite the support of newspapers and both major political parties.  Nevertheless, some municipalities had since introduced female suffrage at a local level, starting with Vaduz in 1976, and women had been elected to the local councils of Vaduz and Gamprin in 1983. St. Silvester (French: "Saint-Silvestre" ) is a municipality in the district of Sense in the canton of Fribourg in Switzerland.  It is one of the municipalities with a large majority of German speakers in the mostly French speaking Canton of Fribourg. Frederick C. Silvester (1901–1966) was an organist and composer.  Silvester studied organ with C. Spencer Heap in England and, after moving in 1921 to Canada, with Lynnwood Farnam in Saskatoon.  During his eight years there, he was organist at the First Baptist Church and Knox United Church.  He moved to Toronto in 1929, studied at the TCM with MacMillan (organ) and Willan (theory and composition), and was organist 1931-1938 at the Church of the Messiah and 1938-1966 at Bloor Street United Church, where he led the choir in many large works.  At the TCM he served at first, 1929–1946, as registrar of examinations, and then, 1946–1966, as registrar.  He gave organ recitals in many parts of Canada and on the CBC and was president 1945-1947 of the CCO.  He was also assistant conductor and coach 1942-1957, and conductor 1957-1960, of the Toronto Mendelssohn Choir.  Of his work with the choir, George Kidd wrote, 'The overall effect is one of good discipline, a clear understanding, and a sincerity that spreads itself over all sections'.  Silvester wrote a number of short choral works (published by Harris) and songs (published by Western).  His Chorale "Prelude on Rockingham" has been recorded by Eric Robertson. The S2 is a railway service of the S-Bahn Zürich on the Zürcher Verkehrsverbund (ZVV) transportation network, and is one of the network's services connecting the cantons of Zürich with the cantons of Schwyz, Glarus and St. Gallen. HERMES 5 is a project management method for IT, services, products and business organisations and was developed by the federal administration of Switzerland.  This method is an open standard available to all.  Many cantons, cities, educational institutions and private sector companies have successfully introduced HERMES 5. The Cantonal rebellion was a cantonalist uprising that took place during the First Spanish Republic, starting on July 12 of 1873 in Cartagena.  In the following days it spread through many regions including, Valencia, Andalusia (especially Granada), Cartagena (which endured for several months the besieging army of Nicolás Salmerón) and in the provinces of Salamanca and Ávila, all of them in places that came to articulate cantonalism.  It can also be noted, the attempt to establish cantons took place in Extremadura, Coria, Hervás and Plasencia.  Pi y Margall, seeing that cantons declared independent by the tardiness of the taxation of improvements, resigned from his post to be succeeded by Salmerón.
