Question: Among the notable structures in the town are the three forts built by the Swedes for defense purposes. One of these forts, known as Fort Oscar (formerly Gustav Adolph), which overlooks the sea is located on the far side of La Pointe. However, the ruins have been replaced by a modern military building which now houses the local gendarmerie. The other fort known as Fort Karl now presents a very few ruins. The third fort built by the Swedes is the Fort Gustav, which is also seen in ruins strewn around the weather station and the Light House. The fort built in 1787 over a hill slope has ruins of ramparts, guardhouse, munitions depot, wood-burning oven and so forth.

Answer: Who built the three forts on St. Barts?


Question: Though much of Enlightenment political thought was dominated by social contract theorists, both David Hume and Adam Ferguson criticized this camp. Hume's essay Of the Original Contract argues that governments derived from consent are rarely seen, and civil government is grounded in a ruler's habitual authority and force. It is precisely because of the ruler's authority over-and-against the subject, that the subject tacitly consents; Hume says that the subjects would "never imagine that their consent made him sovereign", rather the authority did so. Similarly, Ferguson did not believe citizens built the state, rather polities grew out of social development. In his 1767 An Essay on the History of Civil Society, Ferguson uses the four stages of progress, a theory that was very popular in Scotland at the time, to explain how humans advance from a hunting and gathering society to a commercial and civil society without "signing" a social contract.

Answer: In what work did Ferguson explain how humans advanced from a hunting and gathering society to a commercial and civil society without "signing" a social contract?


Question: 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.

Answer:
What kind of island is St. Barts?
