Title: ... on this occasion I'm at a loss.  There was an item entitled:<p>"Unanswerable multiple choice question"<p>and it was here: http://news.ycombinator.com/item?id=1363393<p>There was a lively discussion, and it got lots of upvotes.  That, of course, of itself does not mean it was on-topic, but the guidelines say:<p><pre><code>    On-Topic: Anything that good hackers would find interesting.
              That includes more than hacking and startups.  If
              you had to reduce it to a sentence, the answer might
              be: anything that gratifies one's intellectual
              curiosity.
</code></pre>
This particular question was a great example of that last point.  Treated carefully
it can be used as a starter for paradoxes of all kinds, and self-referential discussions that can lead to correct and appropriate explanations of Goedel's theorems, recursion, formal systems and probability.<p>I will almost certainly now be using it in my next math club talk, and have already started discussions about it with colleagues in the local university math department.<p>So why was it killed?<p>Probably "the judges decision is final" will reign, but I'm annoyed at this one.
