A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first because it introduces the main topic of Jamaica's history. It gives a broad overview of the island's discovery and early colonization. This follows the rule of Topic Sentence. It does not use any pronouns or definite articles that refer to previous information, making it independent. 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 "The capital," which uses a definite article and assumes prior knowledge. Paragraph 3 starts with "Despite disasters," which is not a general statement. Paragraph 4 starts with "Attractions include," which also assumes prior context.

Concluding sentence: Why this is the last line? This paragraph is the last because it summarizes the key attractions of Kingston. It brings together earlier points about the city's history and growth, following the Summary Style rule.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects to Paragraph 1 because it continues the historical narrative of Jamaica. The Logical Order rule applies here, as it moves from the discovery of the island to the founding of its capital.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 logically follows Paragraph 2 because it discusses the growth of Kingston despite disasters. The Cause and Effect Relationship rule applies here, showing how Kingston has thrived despite challenges.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects to Paragraph 3 because it highlights the attractions of Kingston, showing the city's cultural significance. The Broader to Specific Strategy applies here, as it moves from the general growth of Kingston to specific attractions.
