Explanation:
The central idea of an article refers to the main subject that the article wants to present to the reader. In the case of "Freud's Theory of the ID, Ego, and Superego", the article's main idea is to present the study that led Freud to explain how the components of the subconscious are influential and impacting on the personality and behavior of human beings.
