Answer:
B. Western society misjudges Native American practices.
Step-by-step explanation:
In the given passage from a plea letter written by an Indian father, he seems to suggest to a much larger issue of how Native Americans are perceived and treated in the western American society. The father, Robert Lake, emphasizes on how his son is finding it hard to culturally identify himself amidst the American way of teaching that he is subjected to in school.
Taken from the first part of the letter, the given passage reveals how the young son, Wind-Wolf was labeled "a slow learner" by his teacher despite the fact that he has been through with "quite an education" in his Indian reserve. He then went on to narrate how he had been educated so much more about life, more than the Western society's child would have gotten. So, the main argument of the given passage is that Western society misjudges the practices of the Native Americans.
