"Europe has an important culture."
Translation:Η Ευρώπη έχει ένα σημαντικό πολιτισμό.
Πολιτισμός is direct translation to civilization and κουλτούρα is a direct translation to culture. You can check the summary of this article http://www.differencebetween.net/miscellaneous/difference-between-culture-and-civilization/ that refers to the differences between civilization and culture ^.^
Ευχαριστώ πολύ! This actually clicked right away when you mentioned civilisation (πολίτης ~ citizen, civilian). :)
What is this form έναν that we have in one of the "correct" multiple choice answers? It looks like an accusative, but Neuters in Indo-European languages pretty universally have nominative and accusative the same.
