Pool q: I found these:
Wikipedia---> San Alfonso's pool is 1,000 meters (3/5 mile) long.
http://blog.hotelclub.com/san-alfonso-del-mar-the-ultimate-swimming-pool/----> But then Chilean biochemist, Fernando Fischemann used his revolutionary pool-building techniques to build something the world had never seen before, a 1,000 meters-long swimming pool.
It seems it is 1000m, where did you see 1000 yards?
Spider-man: True, but comics are accepted also. Now if you feel that the specific info is too hard to answer for someone without reading the comics, that is different.
Highest village: Georgia is part of Europe, no debate here. From the links you provided, only the first i could use (the second gives HTTP error). The first one points to Juf and says: The bus climbed steeply on a narrow road past several tidy settlements and wound atop the treeline as it took me to Juf – 2,126 metres above sea level.
Ushguli, the answer marked as correct in the q, is at 2200m. And most of the links you get if you just search highest village in Europe, point to this as answer.
One more thing just in: I confirmed Ushguli as the highest inhabited village in Europe from much more reliable sources outside the Internet
