NOTE
Keep in mind that the validity of a question may change if you adjust a question after a measurement has been made. If the structure and choice of words of the question are updated, the interpretation of it changes. Then you can not guarantee that the answers are valid. Minor spelling correction is okay. But if you want to change more than that, we recommend that you create a new question.
