I want to know the answer to the following question:
Who is considered the most competent Serbian scientist on language?
All the background I'm provided with is that "By far the most competent Serbian scientist on the Dubrovnik language issue, Milan Rešetar, who was born in Dubrovnik himself, wrote behalf of language characteristics: "The one who thinks that Croatian and Serbian are two separate languages must confess that Dubrovnik always (linguistically) used to be Serbian."". Is that enough to answer the question?
