Implementing multiple choice question into game

I have the base game complete and now I want to implement a point system with multiple choice questions. The game is a basic 2 player tank game, but I want the loser to answer a question from a pool of questions to get 1 point if it is answered correctly. The winner would receive 2 points and the he is decided at the end of 5 rounds with point totals. I’m completely lost and do not want to mess up the base game so how would I go about doing this? Thank you for your help
