Cause even if zaanstad is guessed 11% correct. Pretty sure none of those were done on peoples first try. Must have come from people trying to get them all right and retaking the quiz.
I don't even think that people that live in one of the (apparently seven) cities in the region of zaanstad will have given it as an answer ;)
Checked, and apparently it would ve been the next one on this list. (recent study found here https://toponderzoek.nl/2017/07/31/aantal-inwoners/)
But I must add, the quizname mentions cities, zaanstad isn't a city but a collection of them, seven to be precise. The city with the highest inhabitants only has approximately 75.000
Zaandam - 76.804
Assendelft - 23.459
Krommenie (inclusief Krommeniedijk) - 17.226
Wormerveer - 11.803
Koog aan de Zaan - 11.133
Zaandijk - 8.686
Westzaan - 4.621
Would ve been fine with having it on the list if the quiz was, biggest municipalities. But the name of the quiz contains city. (just tried to read the wikipedia entries of municipalities and city proper, things are spinning haha, even in my own language it would ve been complicated I think)
Not even sure I ever heard of zaanstad, Zaandam I did know though.
