This question caught my eye:
It seems to be exaustively answerable by a relevant Wiki article.
Do we have a General Reference closure policy that basically says:
If googling for the question's subject you find a general reference site (e.g. Wiki) as one of first hits
The Wiki page has complete information needed for the answer, fully sourced
The page presents the information cleraly and concisely (e.g. not as a random hard to find set of 5 separate unrelated sentence in a 50k-size text; but let's say a section clearly linked from the article index that obviously contains the answer when looking at an index).
... then the question is "General Reference" and should be closed.
(the above is a somewhat rephrased Science Fiction and Fantasy SE policy).
