Final answer:
A logical structure in informative/explanatory texts is crucial for reader comprehension. Without it, readers may become confused, and the purpose of informing is compromised. Important elements include a clear introductory paragraph, an organized body, and a strong conclusion.
Step-by-step explanation:
If a writer does not use a logical structure to present ideas in an informative/explanatory text, readers might become confused or misunderstand the information. An effective text requires a clear organizational pattern to guide the reader through the content. If details are presented haphazardly, without a recognizable structure, it impedes the reader's ability to follow and retain the information. For example, a structure that begins with minor details and randomly alternates between important concepts and unrelated tangents would definitely not work for an informative/explanatory text. Such a pattern would likely distract or frustrate the reader instead of informing them.
An informative/explanatory text functions as a guide to understanding a specific topic. The introductory paragraph sets the stage by introducing the issue and providing necessary background. A well-structured body, organized around clear categories or reasons, fleshes out the topic with supporting details. Finally, a strong conclusion reaffirms the information presented. Consistency, clarity, and logical progression from introduction to conclusion are key to creating an effective informative text.
