First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of the text, which is about retirement for celebrities. It does not refer to any previous information and sets the stage for the following sentences. This follows the rule of Topic Sentence. Why other lines are not chosen?

Paragraph 3 starts with 'Others remain' which also refers back. Paragraph 4 starts with 'However,' which is a conjunction and does not introduce a new idea.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the main ideas discussed in the text. It uses conclusive words like 'regardless of their path,' which shows that it summarizes the overall theme of the text.
