A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of the review. It uses the rule of Topic Sentence because it gives a clear idea of what a review is. It does not need other sentences to understand it. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, 'Rereading is an important part of the review process' starts with a verb and needs more context. 'It is a review of what you are supposed to accomplish not what you are going to do' uses 'it' which refers back to something else. 'Reread with the idea that you are measuring what you have gained from the process' also starts with a verb and needs more context.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it gives a final thought on rereading. It uses the rule of Conclusive Words because it wraps up the ideas about reviewing and rereading.
