We have here more than 15 questions,
and the more questions we have, the more difficult it'll be to navigate through them.
Collapsing elements can help to focus on one part of the quiz, so, you can collapse Parts.
Same for questions, where we can collapse questions at each part one by one.
Same for the questions of part two and part three.
Now, it's easier to have a narrowed vision over each section of the quiz.
