Assuming you know how to get the snapshots, and each document has only one question, which is what you have pictured:

Map<String, Map<String, bool>> questions = snapshot.data();

questions.forEach((question, options) {
  options.forEach((option, value) {
    if (value) {return option;}
  });
});

question is fourthQuestion.

option is each possible answer? 1-2, 13 or more etc.

and value is t/f
