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.
St. Silvester is French for Saint-Silvestre.
It's actually the exact opposite. It states this in the text, but the term "French for" seemed to get confused and it marked correct because of proximity (is my guess).
