Answer:
D. uncivilized
Explanation:
Since no word is italicized, I'll explain the word "barbarous", it being the only word that could be troublesome. The word comes from Greek "barbaros" which was the term for people not speaking Greek.
Romans later took the word and in Latin it meant "the one who comes from outside of Roman Empire".
Basically, the term meant "foreigner". But, since these foreigners came from territories and tribes that were on a less cultural and civilizational level then Romans, this term soon denoted someone who is savage, uncivilized, brutal.
Answer: to describe the meaning of the shell strings.
In this excerpt, the author explains to us what the meaning of the shell strings is. He tells us that the shells symbolize the union of the nations. Option B is incorrect, as the passage does not discuss anything related to the consequences of disobeying one's tribe. Option C is similarly incorrect, as the passage does not mention any of the traditions of the Lords. Finally, the passage does not explain the history of each tribe.
I would say the best answer is A. Answer choice B is rather absurd and answer choice C doesn't exactly make any sense.
