Which step helps strengthen a conclusion without introducing new evidence?

• A. Introduce a new example.
• B. Repeat the introduction.
• C. Summarize key points, restate thesis, and provide final thought.
• D. Add a counterargument.

Answer: (C)

Finishing strong in a piece means reinforcing what you've already argued without bringing in new evidence. Summarizing key points helps readers see how the parts fit together, and restating the thesis reinforces the main claim in light of the evidence you've presented. Adding a final thought provides closure and leaves the reader with a memorable takeaway or a sense of relevance. Together, these steps finalize the argument clearly and cohesively.

Introducing a new example would add fresh material and evidence, shifting the reader’s focus and weakening the closing. Repeating the introduction would feel redundant rather than strengthening. Adding a counterargument introduces opposing material that belongs earlier, where you address it, not at the end. This approach therefore best strengthens the conclusion without introducing new evidence.
