In paragraphs 1-4, the author develops her central idea primarily by suggesting that horror stories have several things in common with other kinds of literature. The author discusses the use of suspense in horror, which is a trait shared with many other genres, and examines how the tension in horror stories is built through characters' actions and settings. Additionally, the organization of horror stories and the different ways events are explained contribute to this central idea, emphasizing similarities between horror and other types of fiction.
If we look at Part A more closely, an analysis of how horror stories are structured to explain events and make them believable is present, but it primarily serves to support the notion that horror shares traits with other literature. Evaluating the effectiveness of techniques used to create suspense could be considered within paragraphs 2 and 3, but it does not encompass the overall development of the central idea throughout the section. Therefore, the best answer is:
- By suggesting that horror stories have several things in common with other kinds of literature.
