Well it's kinda strange - in order to get an Aruban/Dutch passport - you have to take the test in dutch ( the official language of Aruba) and not sure if it has questions about Dutch history/law or Aruban history/law - Not even
sure if there is an Aruban passport - looking at the website below
looks like it's dutch. Which does make sense because it is part
of the Netherlands ...
You might want to try the governor of Aruba - that does have info
about it -
