Best way to display long texts

Hello Unity Community!

I just started trying my second game , which is not 100% game. It will be a quiz 2D game which will also (except than the answers) have the need to display big texts to be shown as extra information after the answer is given.

I guess the UI/Text component is not the best solution and also, copy pastin each and every explenation in a different text component is not particularly pretty practice.

Could you guide me through some useful links/guides or even lessons/tutorials I ll need (except the official ones about UI) in order to make my game the best way possible?

I ve also read something about xml files needed for that kind of games. If anyone has to share any good practices/tutorials on connecting text file databases (for questions/answers of the game) with the Unity engine, will be more than wellcome!

Thanks in advance!
