I'm currently trying to design an editor for an application where quiz questions are linked to specific parts of a passage. This editor is essentially for people to create these type of special quizzes.

An analogous example would be "What if I were making a google form, and I wanted each question to be associated with a specific part of the passage? What would be a good way to implement this?

Currently, my idea is to have the passage on the right of the google forms question making section, and have the user highlight the part of the passage he or she wants to be associated with a certain question.

What are your thoughts on this and do you think there could be potential better solutions (placing the passage somewhere else, completely changing google forms and giving a linear step-by-step tutorial to creating this quiz?)
