Preparation for the end-of-term exam 1

Exam is around here so I have to study for it.
(もうすぐ試験なので勉強しないといけません。)
I have to translate some Japanese into English, and to remember one of the three model answers, but I don't know whether my answer is good and which one is best/natural English.
(英訳をして、模範解答のうち一つを覚えないといけないのですが、私の答えは合っているのか、どの答えが一番自然なのかわかりません。)
Would you help me?(手を貸して下さい。)

本当の国際化とは何か。実際には、この問題が我々の日常生活とはあまりにかけはなれているので真剣な議論がおこなわれることはあまりないように思われる。
Mine: What is real internationalization? Serious argues don't seem occur, because such a question has no relationship at all with our daily life.

Model answer 1: What is real internationalization? Actually, it seems that this issue is so remote from our daily life that we seldom talk about it seriously.

Model answer 2: What does internationalization really mean? Probably the fact is that this subject is too detached from our daily lives to be seriously discussed very often.

Model answer 3:What does internationalization really mean? Actually, it seems that people don't think very seriously about this question because it's not relevant to thier everyday lives.

I'll appreciate your help (*^^)
