Allow - and require! - multiple answers in quiz
It is many questions in a quiz where you want the audience to pick a number of correct answers among the choice they´re given. Example: "In what countries is it allowed to....?" , "Point out the people who have received the nobel prize award!", "Order the bloodtest you want for this patient" etc, etc.
Then of course you want to give points in order to if they have got ALL correct answers (and no more...). There could be an opportunity for the quizmaker to select if either give only points/correct answer if exactly the right choices are made OR you get some pints if you pick one crrect answer, more points if you get ALL correct answers (but no false...)
