题目：
Twenty years ago， Dr. Field， a noted anthropologist， visited the island of Tertia. Using an observation-centered approach to studying Tertian culture， he concluded from his observations that children in Tertia were reared by an entire village rather than by their own biological parents. Recently another anthropologist， Dr. Karp， visited the group of islands that includes Tertia and used the interview-centered method to study child-rearing practices. In the interviews that Dr. Karp conducted with children living in this group of islands， the children spent much more time talking about their biological parents than about other adults in the village. Dr. Karp decided that Dr. Field's conclusion about Tertian village culture must be invalid. Some anthropologists recommend that to obtain accurate information on Tertian child-rearing practices， future research on the subject should be conducted via the interview-centered method.
Write a response in which you discuss what questions would need to be answered in order to decide whether the recommendation and the argument on which it is based are reasonable. Be sure to explain how the answers to these questions would help to evaluate the recommendation.

20 年前，知名人类学F 博士访问了T 岛，并从他的观察中得出结论：T 岛的孩子是由整个村子抚养长大而不是他们的亲生父母。然而，另一位人类学家K 最近对生活在T 岛以及周边一些岛屿的儿童采访显示，他们在谈话中谈到他们呢双亲的时间远远多于谈到村庄里其他成年人。K 博士的这次研究证明F 博士关于T 岛乡村文化的结论是错的，一些人类学家建议要想以进一步获取准确的T 岛的儿童成长规律，未来应该采用采访为主的方法。
