which of the schemes seem(s) most useful for understanding the history of anthropological archaeology in the USA from the nineteenth century through the 1970s?

Hello
For this essay, please use Bruce Trigger’s A History of Archaeological Thought, Second Edition, as the single source of citations.
Also please note that the professor for this class is particular about about citation and bibliography style- please follow the citation guide I’ve attached.
Here’s the essay prompt:
We have discussed three general schemes for understanding the intellectual history of disciplines. Briefly identify and explain those. Based on lectures and Trigger’s book, which of the schemes seem(s) most useful for understanding the history of anthropological archaeology in the USA from the nineteenth century through the 1970s? Justify your response with specific instances of archaeological interpretation. You can use developments in Europe as a point of comparison, but keep your focus on the American case.
The three schemes being referred to here are:
1. Paradigm shift
2. Gradual accumulation of knowledge
3. Social context determines interpretation
There should be writing on all three of these schemes in Trigger’s book- please go ahead and argue for whichever scheme you think you can develop the strongest essay around.
Thank you!
