Terminate:

The survey is over when a responder encounters a Terminate question marked as "terminate." When you get to a terminating question, you can't go back and amend your responses to prior questions. There can't be any more questions on the same survey page as a terminating question. Most survey authors include at least one, and in some cases numerous, concluding items on different pages in their surveys. The termination question is frequently used to dismiss a responder who, based on his or her replies to prior questions, is ineligible to complete the survey. In your survey, you can ask more than one concluding question (for example, one for disqualified respondents and another for qualified respondents).
The panel may disqualify people who post irrelevant things and their answers do not match the survey requirements. Always, go through the questions properly and then answer them.

By administering comparable questions to the target audience several times over several weeks, months, or years, panel surveys can follow changes in behavior over time. A panel survey provides more information than a single-point-in-time survey.
Understanding how variables influence the thoughts and behavior of survey panelists is one of the advantages of a panel survey.
