All of the above answers are correct. An author may use an allusion in writing to make the reading more difficult, to add layers of meaning, to make the reading more personal, or to add a figure of speech. An allusion can serve several purposes, such as referencing a well-known literary work, historical event, or cultural reference, which can enhance the reader's understanding and engagement with the text. Additionally, allusions can create a sense of depth and complexity by connecting the present work to a larger body of knowledge or context.
