I want to know the answer to the following question:
The Slav subgroups have had notable cultural contact with what kind of civilisations?
All the background I'm provided with is that "Slavs are customarily divided along geographical lines into three major subgroups: West Slavs, East Slavs, and South Slavs, each with a different and a diverse background based on unique history, religion and culture of particular Slavic groups within them.". Is that enough to answer the question?
Answer: no
