I would like to learn something about Tristan da Cunha's demographics. 
 Tristan da Cunhan is a group of volcanic islands settled by 200 settlers in 1963. 
 Can you tell me about the economy of Tristan da Cunha? 
 Yes it has no airstrip and therefore is not accessible by air. It uses the U.K pound sterling as its currency. 
 Do you have some information about the culture? 
 I am sorry I don't have more information about their culture. Would you like more information about their history? 
 Sure. Tell me about the history. 
 In World War II, the Royal Navy commissioned Tristan to monitor Nazi boats. 
 Can you tell me some more about the economy? 
 Yes due to restricted air travel, fishing boats often service the islands from South Africa. 
 I think I have enough information. Thanks. 
 Anytime!
