I want to know the answer to the following question:
What does Southern Russian have a linguistic continuum with?
All the background I'm provided with is that "~u̯/ and palatalized final /tʲ/ in 3rd person forms of verbs are also present in modern Belarusian and some dialects of Ukrainian (Eastern Polesian), indicating a linguistic continuum.". Is that enough to answer the question?
Answer: yes
