C

Hi @bihaoqing@gmail.com Happy to help! Answer choice (C) is incorrect because Russell and Praz are mentioned as examples of authors who have written one type of study about Byron i.e. the study of Byron as a figure important in the history of ideas. This type of study is never discussed again in the passage, so we cannot conclude that the author believes that they suggest a new direction for Byron scholarship. Hope this helps! Please let us know if you have any further questions.
