Full question is:

Why are Right-wing extremism (reactionaries) orientated towards the past, more realistic, supports the current system or wishes to improve upon it, and often defends nationalist
issues?

Absolutely NO PLAGIARISM !!!
These will be 5+ pages each (they can and should be longer), based on a Chapter Question, starting with the textbook then at least five other sources from any legitimate mainstream book, journal article, periodical, or newspaper.
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).

In the book is just some basic info, mostly it needs outside sources and the more sources, the better it will get.
And citation is extremely important as well. Do at least 4 or 5 citation and references. Just remember, we need to cite from the book, but not much, mainly looking for outside sources.
