Setting up survey questions can help you to organize and collect valuable data about your contacts. There are a few ways that you can answer this survey. The most common way is by appending the questions widget to your Registration Form (included on the default form) so that contacts can submit their answers themselves. You will also be prompted to answer these questions any time you manually enter a contact on Spark. If you skip the questionnaire at this stage, or add more questions later on, you can always edit a contact's answers by going to the Q&A section of their profile.
You can find your question set-up page by clicking on Forms > Project Questions in the left side menu from your project in Spark.
