I recently failed the following review audit. I voted to close for "no context," but the system said it was a good question.
The irony here is that, before voting to close, I struggled with this one precisely because I do personally think it is an interesting question that is worthy of remaining on the site. However, my understanding was that we agreed as a site to close questions that are statements of problems without any background or work shown, so I voted to close.
I don't know an objective criterion for determining which questions have no-context. Should I only vote to close no-context questions if I find them uninteresting? This seems awfully subjective.
