Answer:
D). Sentence 3.
Explanation:
As per the question, the third sentence least supports the central idea of the given passage. The <u>key idea of the passage is to inform the readers about how Aztecs learned the process of preparing red dye by using cochineal(insect) and its associated aspects like(the reason for which people stopped using it or the latest interests in it again)</u>. The third sentence tells the reader about the period in which artificial dyes came into existence which is completely out of the context and irrelevant to the central idea. Hence, <u>option D</u> is the correct answer.
From what I see D must be the answer because anybody who uses somebody's work is obviously against the law. Also if you think about how school teachers say constantly to make sure it is your own work. It doesn't matter if they are a relative, If you copy somebody's work or use it as your it could be considered plagiarism and even stealing. considering plagiarism is stealing somebody's research or work it is against the law.
I know I added quite a bit but I answered your question. Hope you got the answer you were looking for.
