First sentence: Why this is the first line? This paragraph is the first because it introduces the main topic about high-end fashion and children's clothes. It gives a broad overview of the trend in the fashion industry. It does not refer to any previous information, so it stands alone. Why other lines are not chosen? Paragraph 2 starts with "Jean Paul Gaultier," which is a specific name and does not stand alone. Paragraph 3 starts with "But for France's Bonpoint," which uses a conjunction and refers back to the previous idea. Paragraph 4 starts with "Since Bonpoint was founded," which uses the definite article "the" and assumes prior knowledge.

Concluding sentence: Why this is the last line? This paragraph is the last because it provides background information and wraps up the discussion about Bonpoint. It summarizes the brand's history and its focus on children, which ties back to the main topic.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): This pair connects because Paragraph 2 gives examples of designers mentioned in Paragraph 1. It follows the Broader to Specific Strategy, where the first paragraph talks about a trend, and the second provides specific names.
• Pair 2 (Paragraph 2 → Paragraph 3): This pair connects because Paragraph 3 contrasts with Paragraph 2. It uses the Contrast rule, showing that while some designers launch lines, Bonpoint focuses on children's clothing as its main business.
• Pair 3 (Paragraph 3 → Paragraph 4): This pair connects because Paragraph 4 gives background information about Bonpoint. It follows the Logical Order rule, where the third paragraph states Bonpoint's focus, and the fourth explains its history.
