I have a course I created back in November 2020. Two of the quiz questions are set up as a fill-in-the-blank freeform. I set it up so the answer would be correct if the learner typed in the right answer for the acronym. I am attaching three images. The first image is what the learner got when testing in the LMS. The second is the correct answer showing in the preview and the third is the triggers used that mark the answers correct. I also used a test LMS site which is just to make sure the course is fully functional before it goes to the production site.
