Principle question driving me crazy

For a principle question, let's say the stimulus was about a scenario and the correct answer choice was to identify the principle in that situation. Could the contrapositive be correct?

Ex: the principle describing the scenario is 'if you run a marathon, you will be tired'

In the answer choices, if one was 'if you're not tired, you didn't run a marathon,' would that be acceptable? Or does it have to be 'if you run a marathon, you will be tired'

Apologies if this is a dumb question!

    It can absolutely present itself in the contrapositive because they’re logically equivalent statements. This happens all the time, particularly with PSA and SA questions.

    To use your example:

    Jonah ran a marathon today, so I can conclude that he will be tired afterward.

    Correct answer: If one isn’t tired, then they didn’t run a marathon.
