According to the speakers, what function has tapa played in the following countr

Tutor: So now you should do more research on the details about different countries.
Helen: Where should I go into now?
Tutor: Well, I think Samoa is the typical place known for its Seaple,
which is hand-painted with representations of the ancestors. Till now, at the most profound events in lives, such as births, funerals, weddings and the investiture of chief, some are with Seaple ropes to add significance and eating to the ceremony.
Helen: OK. Then I can talk about Tonga. It seems to me that the great innovation in Tonga has been developing a simple coarse cloth, which is quick and easy to produce. This is suitable for all sorts of daily functions around the house like bed covers, nets and curtains.
Tutor: Good point. Now what about Cook Islands tapa?
Helen: Well, the Sweallier is of poor quality; consequently, the bread fruit tree is often used. One type of thick cloth, called Tikoda, was wrapped around the poles and used to make the entrances to places of worship, and therefore, was highly regarded in local culture.
Tutor: You might mention Fiji as well, which is interesting, because tapa was actually used as currency there. Fijians used to sail between the islands and exchange tapa for other commodities like canoes or pigs.
Helen: I know that in Tahiti, the tapa cloth is regarded differently, because the patterns are in colour, which is considered more valuable than the usual patterns.
Tutor: You are right about the Tahitians using coloured pigments, but they aren’t more valuable. The colours are only decoration. People enjoy wearing bright robes especially for dancing and competitive games and do it just for fun.
Helen: Oh, I’ll take a note of that. Well, the last place I was going to mention was Tikopia. Even today it’s a common place to see wearing clothes made of tapa cloth. And on many of the other islands, the tapa only come out on special occasions. But here you see people working in the gardens wearing tapa.
Tutor: Sound promising, Helen. I’ll look forward to the presentation of your project.
