Which editing principle best ensures that text remains coherent with the main argument?

• A. Ensure each paragraph has a topic sentence that ties to the thesis and that all evidence supports it.
• B. Ensure every paragraph repeats the thesis word-for-word.
• C. Only the introduction should state the thesis.
• D. Conclusively restate the thesis in every paragraph.

Answer: (A)

Maintaining coherence means every part of the text clearly supports the main argument in a logical, connected way. The best editing principle is to ensure each paragraph has a topic sentence that ties to the thesis and that all evidence in that paragraph supports that claim. This creates unity: the paragraph asserts a specific aspect of the argument, then uses evidence to reinforce that aspect and show how it connects back to the central claim. Readers can follow the progression from one idea to the next because each section is explicitly linked to the overarching argument.

Repeating the thesis word-for-word in every paragraph isn’t necessary and can make the writing feel forced or repetitive. Limiting the thesis to the introduction leaves the rest of the piece without a guiding claim to anchor each section. Restating the thesis in every paragraph would clutter the prose and distract from analysis. By tying each paragraph to the thesis through a clear topic sentence and relevant evidence, the text keeps a steady throughline from beginning to end.
