Hmm, I like your idea for a quiz, but the idea is sort of already taken. I've created this exact same quiz, several months ago. You can check the link if you want proof :) https://www.jetpunk.com/user-quizzes/133714/united-nations-security-council
No worries, I used to struggle with making unique quizzes as well. Hmm, I'd feel like a jerk making you delete the quiz... If you don't mind maybe just link mine in the caveat section and say it was created first or something? Tbh I doubt either of our quizzes will get featured though, so in the long run it doesn't matter :P
