Asking Questions Before Applying?

So on the application page for one of the internships that I’m applying for, there’s an email at the end that says to send any questions that you have to that address. However, from a lot of the stuff I read online, people are saying to not ask questions before you get an interview. Problem is, this internship has an essay portion to it that has a very vague description. Would it be a bad idea to send them an email asking them for a bit of clarification? (It’s more of a self-reflection kind of essay rather than a technical one, so there’s no “right” answer)
