For MC #4 (Mapou, Mauritius), in addition to Mapou for the city, we also accepted Labourdonnais Village, which is located within Mapou. If you listed other locations for the city, those are not correct because the clues did lead specifically to Mapou.
For MC #5 (Las Palmas de Gran Canaria, Spain), the correct city is Las Palmas de Gran Canaria or Las Palmas.
For MC #6 (Palmer Station, Antarctica), this location has no city, and no country because it is in Antarctica. In place of the city your answer needed to refer to the specific place Palmer Station or Anvers Island, because the clues did lead to that specific site. Listing another Antarctic research base at a different location (like Casey or Rothera) is not correct. In place of country, in addition to Antarctica, we also accepted references to the specific region of Antarctica where this Palmer facility is located, or to the United States because of Palmer Station's United States nationality, so long as Palmer Station or Anvers Island were identified in the answer.
MC #7 (Hong Kong, China), the correct city needed you to answer Hong Kong or one of its included suburbs like Repulse Bay or Kowloon; the correct country was China or Peoples Republic of China (Hong Kong is not a country, instead it is regarded either as a city or a Special Administrative Region (SAR) of China.)
For MC #8 (Antananarivo, Madagascar), the correct city is Antananarivo, or Tana.
For MC #9 (Aberdeen, United Kingdom), the correct city is Aberdeen. For the country, in addition to the United Kingdom of Great Britain and Northern Ireland, we also accepted U.K., Great Britain or Scotland.
