Open ended questions in Rise

Hello,

I am considering Rise to build a Leadership training course. One of the requirements is to have fill-in-the-blank questions that are open ended i.e. there is no correct or incorrect answers defined. I tried keeping the Acceptable Answers field blank, but that did not work. Does anyone know if this is possible at all in Rise? That is, can users submit their answers (no word limit) without being told whether their responses are correct/incorrect?
