Step-by-Step: How To Add an Explanation to a Question
Click on Quizzes.
Note: If you are creating a new quiz, click Add Quiz; from here you may supply explanations as you add questions.
Next, select a quiz from the list; doing so opens the Edit Quiz window.
Find the question for which you would like to add an explanation and click the Edit button.
In the Explanation section below the question, provide your explanation.
Click Save or Save & Exit to save your changes.
Note: Your explanation will appear at the bottom of the Instant Feedback dialog after a student answers the question, regardless if they got it right or wrong. If the quiz is being delivered in Open Navigation mode—or if you have Show Question Feedback disabled—students will not see the explanation.
