Answer:
The answer is c. Ethical and moral lapses toward the end of the twentieth century led to changes in attitude about the role of the anthropologist.
Step-by-step explanation:
The American Anthropological Association’s “do no harm” mandate came into existence after a five year research in which most of the association’s members felt ashamed over the ethical and moral lapses involved in their work, especially as it promoted American imperialism towards the end of the twentieth century. “Do no harm”, which is the first of seven main principles in the association’s “new code”, encourages anthropologists not to harm the dignity or beliefs of people—non-Americans and Americans.
