While working on her research paper about the French Revolution, Tamia stumbles upon an article on a French museum's Web site. The author of the article is not named, and there is no publication date. She also finds a book by famous American historian Thomas Carlyle. It was published in 2006. Both of these sources would be good for Tamia to use. However, which of these is the most credible source for her paper? A. the article on the museum's Web site because it lacks an author
B. the French museum's site because Carlyle is an American
C. Thomas Carlyle's book because he is a well-known historian
D. Carlyle's history book because it was probably published earlier
