Where Indonesia trips people up

Malaysia is a wrong choice for Jakarta and again for Indonesia's flag and outline. In the flag round the other choices are Malaysia, Singapore and Thailand. For the outline, the other choices are the Philippines, Malaysia and Japan. Malaysia is on both lists.

One trivia question is “Which country has the most active volcanoes?” (Indonesia). Then: “What currency does Indonesia use?” (Rupiah). Numbers: a population of 285 million, independence declared in 1945 and an area of 1,905 thousand square kilometres. Mount Agung and Tambora, two of 13 Indonesia photos, are marked easy; Mount Bromo is marked hard.
