Writing Prompts

On the Common App, it says IIT has 2 required questions and 2 optional questions for writing prompts. I found the 2 required ones (“Why are you interested in IIT” and “Why are you pursuing your major”), but where/what are the two optional prompts? Is one of them to elaborate on an activity in the activity section?

Thanks for any help with this.

The second optional prompt is a resume. That is needed for the Duchossois Scholarship application and is optionally available for any applicant.

That makes sense. Thank you!
