Final answer:
Mark Twain did not specify a new name given to the Garden of Eden by Eve, and the provided references do not contain a direct answer to the student's question. The references explore American cultural landscapes that carry symbolic meaning, which might suggest an idyllic renaming resembling the biblically Eden, or a critical one reflecting society's flaws.
Step-by-step explanation:
In Mark Twain's narrative, he uses the concept of renaming the Garden of Eden to reflect contemporary American culture. There is no direct answer within the provided references that states what Twain had Eve rename the Garden of Eden to, making it unclear what 'current place most Americans knew about' is being referred to. The references include a variety of symbolic American landscapes, such as the New England Village, Small Town America, and the California Suburb.
These sites are deeply ingrained in American culture and could represent an idyllic or utopian aspect similar to the biblical Eden. However, Twain's writings often contain satire and social criticism, which could suggest that any renaming would carry a critical tone, possibly reflecting on the vanity and materialism of society, like the Vanity Fair mentioned in the first reference. Scholars of knowledge theory might argue that such names come pre-loaded with cultural associations that are 'always already' understood by Americans.
