Task: Question Generation
Input (English): Saint Barthélemy, a volcanic island fully encircled by shallow reefs, has an area of 25 square kilometres (9.7 sq mi) and a population of 9,035 (Jan. 2011 estimate). Its capital is Gustavia[citation needed], which also contains the main harbour to the island. It is the only Caribbean island which was a Swedish colony for any significant length of time; Guadeloupe was under Swedish rule only briefly at the end of the Napoleonic Wars. Symbolism from the Swedish national arms, the Three Crowns, still appears in the island's coat of arms. The language, cuisine, and culture, however, are distinctly French. The island is a popular tourist destination during the winter holiday season, especially for the rich and famous during the Christmas and new year period.
Output (English): What country besides France had colonies on the island for a substantial period of time?
