And overall view about REALISM, do research on books and material provided first, then think about larger issue. This should NOT be a book report.

Absolutely NO PLAGIARISM !!!
These will be 13 pages each (they can
and should be longer), based on a Chapter Question, starting with the
textbook then at least two other sources from any legitimate mainstream
book, journal article, periodical, or newspaper (in that order of
importance; email me if you are unsure of a source’s legitimacy).
No
dictionaries or encyclopedias, especially Wikipedia, are allowed. You
must properly cite a source using the APA Style for anything that is not
common knowledge, let alone if you quote from it. The more sources and
citations, the better your grade will be (good social science needs
cited facts to back it up). I will also expect these
Use standard formatting (double-spaced, 12 point Times or Times New Roman, normal margins, page numbering, etc.).
Do not do a Title Page or sub-headings. Do a Works Cites section (which will not count for length).

I also attach a essay example of what the professor expected so you have a better idea.
Thanks.
