The correct answer is A) DNA analysis of people on the islands compared to other people and B) the success of an explorer who sailed on a raft from South America to Polynesia.
Explanation: Scientists used DNA analysis to trace the genetic links between the indigenous people of the islands and populations in other regions, which helped reveal how these ancient populations migrated. Additionally, studying the successful journey of an explorer who made a similar trek provided practical insights into the possible routes and navigational methods used by ancient peoples.
