When students take a multiple matching quiz, it is very confusing for them to continue to see answer options in the drop down list after they have selected them as an answer. See in the pic below how "rising, beginning, origin" was selected as the first vocab answer, but is still available in the drop down list of choices for all of the following questions. It would be best if instructors had the option to choose if answers should be used only once to eliminate them for the list OR, allow for the answers to be used again. Please consider this feature request to eliminate confusion for students. Thanks!
