In a survey one might like to ask for more detail if a respondent answers possitive/negative on a question, while an opposite answer might imply a number of questions are not relevant anymore. Therefore it is necessary to set up an option to ask additional questions if an particular answer is given. For this I see two scenario's; 1. Skip option; if a respondent answers X (instead of Y) on a question, a number of additional questions is skipped. 2. Sub questions; a main question is created, only if a respondent answers a specific answer additional subquestions will be asked. For example; Do you like alcoholic beverages? => If answered yes; ask subquestions. E.g. what alcoholic beverages? Beer, Bacardi, mix, cocktail, etc. => If answered no; go to next question.
