Ways and instructions to tell a user to intentionally miss a multiple choice question?

I'm currently brainstorming possible solutions to this UX question. In a multiple choice activity (not a quiz/form), if a user correctly answers a question, before they move on to the next question, I want to encourage the user to still click on the wrong answers and see the feedback from the wrong answers, so they understand why the wrong answer is wrong.

My first question is placement of these instructions: I was thinking about putting optional instructions either before the question, or after the last multiple choice answer. The reason I suggest the latter is that these set of instructions are rather unique, and could possibly disrupt the natural user flow of reading a question and answering the questiion.

My second question is about the actual contents of the instructions are a question mark to me. I was thinking:

  1. Direct Approach: If you get the answer right, please also take a look at the other answers to see why they're wrong!
  2. Subtle approach: Choose the best answer, but be sure to go through all the answers later!

I was also wondering in terms of user experience if it would make more sense to put these "instructions" after the user has successfully answered thee question, rather than before?
