Sometimes you want to survey a certain subset of people that you aren't able to target in the targeting section. In this case you can ask the question in your survey and reject those who shouldn't qualify for the survey.
This is done by changing the answer option to "Reject" instead of "Accept".
If a respondent selects the "Reject" answer option, then they won't answer the remaining questions.
Always keep any questions with a "Reject" option at the beginning of the survey.
