A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces Maya Angelou. It gives a clear overview of who she is. This follows the rule of Topic Sentence because it sets up the main topic without going into details. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, Paragraph 2 starts with "Over the course" which is not independent. Paragraph 3 uses "Angelou's most famous work" which needs context. Paragraph 4 starts with "The book begins" which also needs prior information. Paragraph 5 starts with "As the book develops" which is not independent.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the ideas in the text. It shows how the book ends and reflects on Angelou's growth. This follows the Conclusive Words rule because it summarizes the main themes of the book.
