It is curious because, in each of the questions I encountered problems with the own questionnaire and I tended to answer in the way the writer thought. And then you find "it's a trap". I think the questionnaire is not honest enought, a better answer for D should have been: "we need more information" or "there are programming inconsistences"... I thought that when selecting "I don't know" I was telling "I don't know what's happening with the code and the inner datails".
