Fill in the Blank Quiz

Hello, 

I have searched the community, and have found a few articles on fill in the blank, graded questions. What I have found is the triggers dont quite work with what I am trying to do. We have a compliance module I am creating, and one of the quiz sections is we want them to identify the acronyms. Example: DOT = Department of Transportation. Ive found the examples of triggers for multiple fill in the blanks doesnt work with longer answers for responses like Department of Transportation. Does anyone have any suggestions? Ive attached the quiz page for ideas and thoughts!
