Answer:
Your new-caught, sullen peoples, Half-devil and half-child.
Step-by-step explanation:
Ethnocentrism is the philosophy or social belief that involves judging other cultures based on one's own culture. In other words, we can say ethnocentrism is the practice of basing one's own culture to talk or judge other cultures.
In the given lines from Rudyard Kipling's poem "The White Man's Burden", ethnocentrism is found in the line "Your new-caught, sullen peoples, Half-devil and half-child." In this line, the speaker, obviously a white person, refers to the natives as "sullen people, half-devil, half-child." This derogatory language is used to refer to the inferior nature of the natives as compared to the white men who are there to "carry the White Man's burden."
