A yes/no question asks a respondent to answer a question by choosing either yes or no (true or false).
Skip logic is an advanced choice option that redirects the respondent to the designated page based on the answer they chose. This feature is turned off by default. To enable skip logic, clicking the question's settings icon and select “Yes” for the Show Skip Logic option.
