With this pull request, the ConfirmationQuestion can accept one (or many) answer(s) like 'o', 'oui' (in french) or 'si' (in spanish) or anything else, it's up to you !
Default value is still 'y' (yes)
What about naming the variable `$correctAnswers`? `$rightAnswers` to me, implies that there's also a `$leftAnswers` and makes a cross-comparison.
