Fill in blank quiz question

Hello Storyliners, I am trying to do the same as Lee, above here, with a quiz question that has multiple fill in the blanks to complete a paragraph. I couldn't access the Peek that Lauren posted above, while I did download the Lee_1.8.2021.story and adjusted that, but I don't see where I can fill in the correct answers, and I do not get what those text boxes "correct" and "incorrect" outside the slide frame do there. I am an absolute beginner in Storyline. I only worked with Rise and now want to import two Storyline questions into my Rise quiz, where one is supposed to be this fill in multiple blanks exercise...
