I was reviewing when this question came up for closing votation with 3 votes to close. After reading said questions and the comments I'm uncertain on how to vote and would like to ask clarification (I couldn't find a satisfying policy, maybe this or this one applies).
The question, seems to me, asks for concise information and it is possible for it to have a definitive answer. The OP claims he is not familiar with the original material so he is not asking for speculation but for a concise answer. However, it is true that currently it has no answer beyond speculative ones (we might get an answer in the future though).
So, how do we procede with adequate questions that might have a definitive answer but right now invite speculation?
