Here's why:
* Recap of Main Points: Topic sentences summarize the main points of each paragraph. Reviewing them helps you remember the core arguments you've made and ensures your conclusion effectively ties everything together.
* Unified and Coherent Conclusion: By referring to your topic sentences, you can create a conclusion that is consistent with the overall flow and structure of your essay or paper.
* Strong Summary: A good conclusion restates the main points without simply repeating the introduction. Looking at your topic sentences provides a framework for a concise and impactful summary.
Example:
Topic Sentence: "The Industrial Revolution led to significant advancements in technology, but it also had a profound impact on social structures."
Conclusion: "While the Industrial Revolution undeniably propelled technological progress, it also caused widespread social upheaval. From the growth of factories to the urbanization of cities, society underwent a dramatic transformation. This period marked a turning point in history, forever changing the landscape of human life."
By referencing the topic sentence, the conclusion effectively summarizes the main point of the paragraph while providing a broader perspective on the topic.
