quite an interesting way to teach topic sentences, because the answer to this question is the best definition of a topic sentence that one can present, it is as if answering the questions taught you how to do it, this is some real teaching, it is terribly well-done.

the topic sentence in this paragraph is:

which incidentally tells you what a topic sentence should be.

different strategies reach different people based on their ability to understand the material. (from personal experience) when writing an argumentative essay write explaining the subject as though your audience never heard of it before and it is just being introduced, then explain why other people hate it also, afterward you would explain why that would be wrong. i hope that : )
