From one of several internet sources: "According to several authoritative sources, such as the CIA World Factbook, the Times Comprehensive Atlas of the World and the US Department of State, only two countries, The Bahamas and The Gambia, should officially be referred to with the article." So, The Gambia is definitely missing, but "The" Vatican? The state is officially called Vatican City, there is no article included. Please double-check your facts before you go along with someone's silly suggestions. Better yet, just scrap the whole "'The' included" thing, no other quiz does that.
