premise: The Kuršininkai (Curonians; German: "Kuren" ; Lithuanian: "kuršininkai, kuršiai" ; Latvian: "kursenieki, kurši" ; Polish: "kuronowie pruscy" ) are a nearly extinct Baltic ethnic group living along the Curonian Spit. "Kuršininkai" refers only to inhabitants of Lithuania and former East Prussia that speak a dialect of Latvian.
hypothesis: The Kursininkai have been extinct for a long time now.
reason: My statement is definitely incorrect because they are not extinct yet. Maybe the system doesn't know what "nearly" means.
