Answer:
For researching the original character of Mulan from a poem written almost 1,000 years ago, the most credible source to use would be "an article in a historical magazine about how the mythology around Mulan is changing."
Here's why this source is the most suitable:
Relevance: The article in a historical magazine focuses specifically on the mythology around Mulan, which aligns with your research objective of understanding the original character from the ancient poem.
Authority: A historical magazine is likely to have rigorous editorial standards and fact-checking processes, ensuring a higher level of credibility and accuracy compared to other sources like blog posts or movie reviews.
Expertise: The article is likely to be written by historians or experts who specialize in Chinese history or literature. Their research and expertise in the field make them reliable sources of information.
Academic Approach: A historical magazine article is expected to present information in a scholarly manner, supported by references to primary sources, citations, and a critical analysis of historical context. This can provide valuable insights into the original character of Mulan.
While the other sources, such as a movie review, an interview with a literature professor, or a blog post from a woman claiming to be related to Mulan, may provide interesting perspectives, they may not offer the same level of credibility and depth of historical analysis needed for research on the original character from an ancient poem.
