I have to agree with WT2008 and cpgatbyu. Your reply that "Arctic isn't an ocean..." is correct, but if you're going to accept "Mediterranean" specifically without the word "sea", then just "Arctic" should be accepted as well. I say this because geographically speaking, of "Aegean", "Mediterranean" and "Black", "Mediterranean" by itself can mean something other than a sea (although you could argue that "Black" by itself could mean the large forest area in Germany)...similar to using just "Arctic" by itself, which was the point in your initial reply to cpgatbyu.
Difficult to answer the "what 3 major seas does Turkey border question". Shouldn't there be 3 answer boxes? I typed "Black" and I typed "Aegean" and they were not accepted. Do you have to type all 3 in the right order, with commas, etc in order for it to work?
Liechtenstein isn't the only country to border Switzerland and Austria, France and Italy do as well. I believe you mean, 'Which country only borders Switzerland and Austria?'
Northernmost point – Kure Atoll, United States (28°25′N)
Southernmost point – Jacquemart Island, New Zealand (52°37′S)
Westernmost point – Dirk Hartog Island, Australia (112°55″E)
Easternmost point – Easter Island, Chile (109°13'W)"
So which hemisphere do you think is missing?
