It's a good quiz, but I'm afraid the data must have a problem. If it is counting citizens who visited the country, Singapore and Brunei have impossible numbers. Singapore has a population of 7 million people, so how could 13 million Singaporeans have visited Malaysia? It gets even more rediculous with Brunei, as Brunei has only 400k people, yet the data claims over 1m citizens of Brunei visited Malaysia. Again, it's a good quiz, only the data seems to have issues.
