The document discusses paragraph writing and its key components. A paragraph contains a topic sentence that introduces the main idea, followed by primary support sentences that directly relate to the topic and secondary support sentences that provide additional context. A concluding sentence wraps up the key points. For example, a paragraph about tourist attractions in Peshawar would have a topic sentence introducing places to visit, primary support sentences on Islamia College, Bala Hisar Fort and the Peshawar Museum, along with secondary support details about each location. In conclusion, Peshawar has historically been an exciting place for people to visit.
