题目：
The following appeared in an article written by Dr. Karp， an anthropologist.
"Twenty years ago， Dr. Field， a noted anthropologist， visited the island of Tertia and concluded from his observations that children in Tertia were reared by an entire village rather than by their own biological parents. However， my recent interviews with children living in the group of islands that includes Tertia show that these children spend much more time talking about their biological parents than about other adults in the village. This research of mine proves that Dr. Field's conclusion about Tertian village culture is invalid and thus that the observation-centered approach to studying cultures is invalid as well. The interview-centered method that my team of graduate students is currently using in Tertia will establish a much more accurate understanding of child-rearing traditions there and in other island cultures."
Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.

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，我最近对生活在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。我的这次研究证明F博士关于T岛乡村文化的结论是错的，因此这种以观察为主的文化研习方式也是无效的。由于我那些在T目前调研的研究生们正是采用我的采访为主的方法，所以他们将会对T岛孩子抚养传统已经其他岛屿文化给出更加精确的了解。
