单选题 .  ①As it was published in 1935, Mules and Men, Zora Neale Hurston's landmark collection of folktales, may not have been the book that its author first had in mind. ②In this anthropological study, Hurston describes in detail the people who tell the stories, often even inserting herself into the storytelling scene. ③Evidently, however, Hurston had prepared another version, a manuscript that was recently discovered and published after having been forgotten since 1929. ④This version differs from Mules and Men in that it simply records stories, with no descriptive or interpretive information.
