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

The argument claims that the conclusion of Dr. Field is invalid and the interview-centered method would be superior than the observation-centered approach in understand the of child-rearing traditions there and in other cultures. The author failed to provide sufficient evidence to support the claims.

Firstly, the sample of this study, children from a group of island including Tertia, and Dr. Field 's sample, only children from Tertia island, is not same. Therefore, it is difficult to compare the conclusion of Dr. Field' study with this result as well as the suitability of the methods used. The author should sort out the data from children from Tertia and build the conclusion based on these data before any comparison with Dr. Field's study can be done.

Building on the assumption that the difference in sample of two studies is insignificant, the fact that children talking more about their biological parents than other adults in the village is not a concrete evidence that the children are reared only by their biological parents. It is possible they are reared by a whole villagers but the contribution from their parents is more than any other single adults but less than total contribution of other adults in the villages. So the extent in which they talking about their biological parents in relation to other adults should be stated out for the evaluation of the argument. In addition, it is also possible that villagers rear the children by providing foods or other commodity rather than spending time with the kids, and as the result, the kids may understate other adults' contribution. If this later fact is proving true, the argument will be significant weakened.

Lastly, the author also generalize that interview-centered method is more appropriate for studying rearing behaviors in in other regions than the observation-centered approach does. The generalization requires evidence from study about other cultures. If study from other region is consistent with the result from Tertia group of island, the argument is strengthen and vice versa, weakened if prove unwarranted.
