I am writing a two-sided essay, and my teacher told me to underline the topic sentence in every paragraph. But I have a problem. First, take a look at the essay structure:
[1] Hook, small context, thesis (P is bad, Q is good).
[2] It is true that P has these benefits. Firstly, A...
[3] Secondly, B...
[4] However, despite A and B, Q is better. Firstly, C....
[5] Secondly, D....
[6] To conclude, [restatement of thesis, P is bad, Q is good] + my final thoughts
A topic sentence is the first sentence in a paragraph and it is the most important sentence in a paragraph. But for the first paragraph [1], is the hook the topic sentence? I don't really think so. Secondly, for [4], the main idea is C, not the turning point. But I have to put the however sentence to show that it is the turning point. Should I underline the first sentence, the second sentence, or both? This is also similar to [2]. Lastly, is there a topic sentence to the concluding paragraph?
P.S. I don't know if I posted in the right stack exchange site with more than 150 different sites. If this isn't the correct site, would you kindly tell me the best site to post this question on? Thanks :)
