In my opinion the answer "airline" does not represent an industry. I would either rephrase the question and remove the mention to "industry", or simply allow "aviation", "air transport", "transportation" or similar answers...
I feel like Russia should be an acceptable answer for the Eastern Bloc question. I kept trying it to no avail and didn't even think to put in the Soviet Union
I feel like government should work for the last clue. According to the Wiki article "An interregnum is a period of discontinuity or "gap" in a government, organization, or social order." I eventually got it after brute forcing a number of different types of governments and leaders but I think that would be a good change.
An argument of etymology vs. definition. I don't know the current definition of interregnum, but the argument of using its etymology isn't really an effective one. By that stance, ambidextrous would refer to someone taking bribes from both sides of a legal dispute, sinister would simply mean left handed and explode (-plode meaning applause) would refer to jeering someone offstage. None of these would be the only expected answer with respect to their definitions nor should narrowing this definition to its original.
I am not a star wars/trek fan, so I thought that the Star Alliance was referring to one of those. Thankfully I suddenly remembered the answer before my time ran out.
I wanna thank Steve Carell for helping me get the fife answer. Listened to his appearance on Smartless last night, where he talked about playing the fife when he was younger. Comparde it to a piccolo. So if you ever come by Jetpunk, Steve: thanks!
Your fourth question is badly phrased and wrong. Russia did not exist as a country, it was the Soviet Union. Whilst they were the clear dominating power they were never regarded as the Leader, it was a coalition of communist states, officially at least.
"Airline industry" is the airline itself. They are quite different.
There is no such thing as the "airline industry", airline sector maybe, but airlines are definitely not an industry...
Russia wasn’t a country when the Eastern bloc existed. The Soviet Union quite famously was.
it was just a constituent part of the USSR.
Governments might rule but they don't reign, that's something that monarchs do.
