To determine which of the options is NOT something to check during a thorough revision, let's examine each one individually:

This involves examining the logical flow and structure of your writing to ensure that ideas are presented in a clear and coherent manner. Organizational improvements can enhance the readability and understanding of your work.

Correcting punctuation errors helps to improve the clarity and precision of your writing. Similarly, addressing spelling mistakes enhances the professionalism and credibility of your work.

This involves checking whether your ideas are well-developed, supported with evidence or examples, and presented in a logically coherent manner. Ensuring clarity allows your readers to understand your message effectively.
