What is the purpose of using QUERYSET when initializing the formset?

@login_required
def answer_form(request, question_pk):
    question = get_object_or_404(models.Question, pk=question_pk)
    formset = forms.AnswerFormSet(queryset=question.answer_set.all())
    if request.method == 'POST':
        formset = forms.AnswerFormSet(request.POST, queryset=question.answer_set.all())
        if formset.is_valid():
            answers = formset.save(commit=False)

            for answer in answers:
                answer.question = question
                answer.save()
            messages.success(request, "Added answers")
            return HttpResponseRedirect(question.quiz.get_absolute_url())
    return render(request, "courses/answer_form.html", {'question': question, 'formset': formset})

What is the purpose of using QUERYSET when initializing the formset?

Any help would be much appreciated. Thank you!
