Which of the following is NOT a function of prewriting strategies?

Prewriting strategies are designed to help writers generate and organize ideas before they begin drafting. The functions of prewriting typically include accessing background knowledge to inform their writing, researching topics to gather relevant information, and visualizing ideas graphically through methods such as brainstorming or mapping. These strategies set the foundation for the writing process, focusing on idea generation and organization.

On the other hand, polishing final drafts falls under the revision and editing stages of writing rather than prewriting. At this stage, a writer focuses on refining and improving the clarity, coherence, and correctness of their work, addressing issues such as grammar, punctuation, and formatting. Thus, polishing final drafts is not a function of prewriting strategies, making it the correct answer in this context.
