- for rank/match/option/radiobutton response types when viewing the submissions or attempting to grade, the responses are shown in foil order, and the correct elements are bolded, the incorrect elements are itailcized, also the same text as used in the 'Correct Answers' display is used to make it easier to compare submissions and see what a student is doing wrong.
