Citation, Documentation of Sources

Q. I am working on a research paper for an upper-level anthropology class and could not find the correct method for citing a quote that contains several in-text citations. How do I address the in-text citations?

A. Include them in your quotation. Please see CMOS 13.7: “Parenthetical text references in the original should be retained.”
