I guess there exist Problem, Question and Answer triplets that need to be adapted before solving. Problems are not always questions. Since you can ask different questions. They are not always related to the problem.
Where in the triplet possibility does the relation lay. What I mean is.
To solve certain triplets the problem might have to downsized or up sized. I guess this could be said for the question and answer also.
Also. Can we be sure we got it right for every problem? There might be probabilities for the triplet. At least to the answer.
