Branching refers to providing a customized experience to the learners based on their actions in the project. In this exercise, you will create the sequence explaining the types of train tickets to the student. What you want to achieve is allowing the student to view the ticket types in any order and as many times as needed. To do it, you will create a slide with three buttons, one for each ticket type. You will also send the student back to this slide after viewing each ticket type.
