Curacao is a bad example for this question. It is a separate country, very nearby Aruba, also a separate country (both inside the Kingdom of the Netherlands, but more independent than for example Scotland, Flanders or a US state). So my expected answer would be Willemstad, the capital of Curacao...
Curacao is a country, but it's not a sovereign state, which geopolitically speaking, is synonymous with nation. Because the directions ask you to "name the nearest national capital," the quizmaster is correct.
So it's a country in the same way that the country music awards are? It's not a country the way the word is used and understood on nearly any quiz on this site.
Not a country the way Jetpunk recognizes it, but it IS one of the four countries within the Kingdom of the Netherlands. Just like the UK is made of four countries as well.
What we're talking about here is the difference between a sovereign country and a constituent country. Curaçao is a constituent country with a high degree of autonomy, but in terms of sovereign countries, it is part of the Netherlands.
The nearest National Capital to Curacao, is indeed Caracas, Venezuela. Curacao and Aruba are countries within the Kingdom of the Netherlands, so you cannot use their own capitals as answers (if they were sovereign states, then the nearest National capital for Curacao would be Oranjestad, Aruba and the nearest National Capital for Aruba, would be Caracas, Venezuela).
Here is a helpful hint: Try typing the name in google search bar. You'll be amazed at Googles AI. I gives a helpful suggestion as to the correct spelling, which you can copy and pasted into the answer box.
The thought that you might have to be right on a quiz seems to escape some people... By having to get the spelling right, it forces you to learn how to spell things correctly.
Why is that funny? It is the capital. But many other countries don't recognize it as such due to the politically contentious nature of the subject of who controls Jerusalem. The city, in its entirety, falls entirely within Israeli sovereignty. It's also the seat of Israeli government being home to the Knesset.
As the very old saying goes, ownership (in this case more like occupation) is nine-tenths of the law. Nonetheless, Israel's occupation for the time being does not confer sovereignty. Even the US (!) still does not recognize Jerusalem as the capital. (So what, by the way, is Tel Aviv?)
Zanzibar caught me, I thought the capital of Tanzania was Dar Es Salaam, when has it become Dodoma?
