Final answer:
A strong conclusion synthesizes the evidence and relates it back to the topic sentence, offering a summary or if-then implications, with emphasis on the key idea.
Step-by-step explanation:
To effectively conclude a paragraph, one must draw a conclusion that synthesizes the evidence and relates it back to the topic sentence. This can often take the form of a brief summary that highlights the significance of the information presented or an if-then statement that suggests potential outcomes or implications derived from the paragraph. The crafting of a concluding sentence should also bear in mind the emphasis placed by sentence positioning, ensuring that the most important idea is what the reader takes away.
