premise: Jyestadeva (1500-1610), was an astronomer of the Kerala school founded by Madhava of Sangamagrama and a student of Damodara. He is most known for writing the first calculus text, the Yuktibhasa . He also authored the Drk-karana on astronomical observations.
hypothesis: Jyestadeva was born in North America.
reason: The statement is indeed neither definitely correct nor definitely incorrect. The text doesn't state where Jyestadeva was born. For all the reader knows, he could have been born in North America, or he might not have been in North America. I think this was difficult for the system to detect because "North America" is terminology it hadn't accounted for.
