Considering that you're refusing to answer the questions upfront, I'm going to assume the answer to all of them is "no" and you simply don't want to admit it (or believe it)
Also to your comment above, World Showcase actually *does* showcase professional exhibits and historical artifacts of the countries it represents.
The pavilion of China actually has a museum displaying some of its nation's ancient artifacts. The American Adventure is narrated by Benjamin Franklin and Mark Twain, who tell the tale of American history from the perspectives of the Revolutionary War, Civil War, Industrial Era, the Great Depression and more. And while waiting for the show, you can browse through several American artifacts or listen to the wonderful Voices of Liberty. After walking through the Japanese gardens you will come to castle and a moat, and inside there is a historical display of Japanese culture.
These are just some of the many examples that World Showcase is much more than what you percieve it to be. Just because you don't think you can learn anything in WS (or don't want to) doesn't mean that it doesn't exist. I for one, learn something new on every trip to WS, either reading signs and observing historical artifacts or simply talking to Cast Members who are native to the nations.
So with all that said, I will try again..I could care less what scenery or clothing in Norway provided "inspiration". What I would like to know, what about the story of Frozen, meaning the characters and songs, is based on Norway? I would like to know especially since the fairy-tale that Frozen is "based on" originated from Denmark, not Norway.
It seems like "it's a theme park" and it's "ruled by a talking mouse" are your fallback when you don't have anything substantial to counter with.
