Which change in a paper would lead to less effective writing during revision?

Combining several main ideas into one paragraph can lead to less effective writing during revision because it often results in a lack of clarity and coherence in the text. Each main idea typically has its own supporting details and context, which are best expressed in separate paragraphs. When multiple ideas are crammed into a single paragraph, it can confuse readers and dilute the focus of each point. This defeats the purpose of clear organization in academic writing, where the reader should easily follow the argument or narrative. Proper paragraph structure helps in maintaining a logical flow of ideas, making it easier for the audience to absorb the information presented. Therefore, keeping distinct main ideas in their own paragraphs is essential for effective communication.
