Multiple choice question with unique feedback for each answer

For multiple response type questions, you could add a Correct or Incorrect state for each answer and change it in some way such as adding checks or x's or changing color to indicate if it is wrong or right. If the slide is set for feedback to occur after the submit button is clicked, they won't get a hint ahead of time. You can do something similar with drag-and-drop; you can change the look of the Drop Correct and Drop Incorrect states to show up after submit is hit.
