Task: Question Generation
Input (English): The opinion of the majority of Croatian linguists[citation needed] is that there has never been a Serbo-Croatian language, but two different standard languages that overlapped sometime in the course of history. However, Croatian linguist Snježana Kordić has been leading an academic discussion on that issue in the Croatian journal Književna republika from 2001 to 2010. In the discussion, she shows that linguistic criteria such as mutual intelligibility, huge overlap in linguistic system, and the same dialectic basis of standard language provide evidence that Croatian, Serbian, Bosnian and Montenegrin are four national variants of the pluricentric Serbo-Croatian language. Igor Mandić states: "During the last ten years, it has been the longest, the most serious and most acrid discussion (…) in 21st-century Croatian culture". Inspired by that discussion, a monograph on language and nationalism has been published.
Output (English): Who stated that the argument between pluricentric or dual standard classifications has been the "longest, most serious, and most acrid discussion in 21st century Croatian culture?"
