Answer:The topic sentence is normally the first sentence in a paragraph. This sentence gives the reader an idea of what is coming up in the paragraph, and it is normally the most general of the paragraph’s sentences. There won’t be a whole lot of detail in this sentence, but it is there to introduce the main idea.The body sentences (or supporting sentences) reinforce the topic sentence by fleshing out the details. If something in the body sentences does not support your paragraph, it needs to go somewhere else in the article probably in a new paragraph. If your topic sentence is the “what” of your paragraph, the body sentences are the “whys.”The concluding sentence is not always necessary, but if you have a longer paragraph, it is something that should be included. The concluding sentence will summarize your topic sentence and reinforce it.
