Reset array after playing the game?

Question

I made a quiz in iOS with xcode, what i have now is a quiz that generates 20 random answers out of an array, it controls the text of the labels when a button is pushed to check

Answer 1

Either make a copy of arrEurope on game start and restore to it when the game is restarted or use some other array to mark a question as removed. I would personally try to use option 2.
