Random trivia question

hye, can someone point me to a right direction,

im kind a new in unity,
I want to build trivia game, SO HOW TO MAKE RANDOM QUESTION. + HOW TO MAKE IT NOT REPEATING THE SAME QUESTION AT THE NEXT LEVELS…?

thanks in advance

Ok so what you want to do is create a list of strings. Each one of those strings can be a question. Then you get a random number between 0 and the last position of the list.
