Below is a picture of a question that needs to be corrected. The question has the answers of 0,2,0,0 to choose from, which would be fine if 2 was the correct answer, however it is not and just selecting a random 0 is not correct either. The correct answer should be 5, and two of the 0 answers need to be changed to 5 and something else like 12 or 8 so that this question can be completed without having to remember which 0 is the right selection.
