I don't know what the odds are of getting accused, but let's say this was in the context of an interview question, and every answer submitted looks almost 100% the same, or even more telling, has the same logic mistakes, then the odds could be high that plagiarism is afoot.

Its the epitome of that thing with Michaelangelo where he assumes his vision for the sculpture is correct and all he needs to do is surgically remove the excess marble to get to the essential form that is perfect and ideal and intutitive.
