Dynamic Survey DB Model - Display Questions based on Logic

I am building a survey application that allows users to create and distribute surveys.

I have the survey DB model almost complete, with the exception of handling 1 part.

I want users to be able to add logic to the survey.

Below is my current DB model, how can I modify this to handle custom logic. Is this even possible?

By logic I mean to show/hide question based on the answer to other questions.

I.e. If (Question 1 == true), then (show Question) 2 else (show Question 3).
