What is one effective way to improve a rough draft?

Revising for clarity, coherence, and grammar is an effective way to improve a rough draft because it addresses the fundamental elements that contribute to strong writing. Clarity ensures that the reader can easily understand the writer's ideas, while coherence helps to organize those ideas logically, making the overall piece more cohesive. Additionally, refining grammar enhances the professionalism and readability of the work. This comprehensive approach not only polishes the draft but also strengthens the impact of the arguments being presented.

The other options do not contribute effectively to the revision process. Ignoring grammar mistakes undermines the quality of the writing, while sharing a draft with friends without editing does not provide a structured way to incorporate constructive feedback. Lengthening arguments can dilute their effectiveness if it leads to unnecessary verbosity rather than focusing on precision and relevance.
