<p>If you cannot decide among answers because it is unclear whether one (or any of them) is correct, <em>then those answers are not good enough for you.</em>  You don't have to award them bounties, acceptances, or even your (up)vote.  What you should do instead is write comments asking for clarification.  Then you can decide on a best answer (if indeed any answer at all is valid) based on objective, rational criteria.</p>
