The three options that can be considered valid sources for online research are:
- The National Archives - This is a reputable, primary source of historical documents and records.
- A weblog of a college history professor about her area of specialty - This can be a valid source, especially if the professor is recognized in their field and provides well-researched content.
- A gov website - Government websites typically provide credible and reliable information, especially regarding statistics, laws, and policies.
The other options may lack reliability and credibility for academic research.
