First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of child stars and their challenges. It does not refer to any previous information and sets the stage for the discussion. This follows the rule of Topic Sentence. Why other lines are not chosen? The other paragraphs are not chosen because they do not meet the criteria for being independent. For example, Paragraph 2 starts with 'They', which is a pronoun that refers back to child stars, so it cannot stand alone. Paragraph 3 starts with 'Additionally', which is a conjunction and shows a continuation of thought. Paragraph 4 starts with 'However', which also indicates a contrast and cannot be the first sentence.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the discussion about child stars. It shows the different paths they can take after facing challenges. This follows the Conclusive Words rule, as it summarizes the outcomes of the previous points.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects with Paragraph 1 because it gives more detail about the challenges mentioned. This follows the Broader to Specific Strategy, where the first paragraph introduces the topic and the second paragraph provides specific information about fame.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects with Paragraph 2 because it adds another challenge that child stars face. This follows the Logical Order rule, as it continues the discussion about the difficulties of being a child star.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects with Paragraph 3 because it shows the outcome of the challenges mentioned. This follows the Cause and Effect Relationship rule, where the stress from managing careers can lead to different outcomes for child stars.
