The central argument is the most important ideological viewpoint put forward by the author in the article, and it is a high generalization and concentration of all arguments. Used in argumentative writing, it is equivalent to the central sentence in narrative text, expressing the idea of the whole article. The central argument is the author's views and opinions on the issues discussed, and it is the soul of argumentative writing. Reading argumentative essays ultimately requires readers to grasp the central point of the article.

How to judge whether it is a central argument can be used to exclude arguments. The way to exclude arguments is to find out all the factual arguments and theoretical arguments on the basis of reading the full text, because arguments are used to prove the facts and reasons of arguments, and they are definitely not arguments.
