Try to keep the number of language variables to the minimum. In this case, AtLeastOneCorrectAnswerRequired ~= MustSelectCorrectAnswer and AtLeastOneCorrectAnswerMustHavePositiveWeighting ~= CorrectAnswerMustHavePositiveScore.
More language variables mean more time for translators, and that means a smaller ratio of translator contributions in the long run.

Nevermind, I just realized it is because of the difference between single answer and multiple answer ! 🤦‍♂️
