A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces Lunenburg and gives a general idea about its location and features. It does not refer to any previous information. It sets the scene for the rest of the text. Why other lines are not chosen? Paragraph 2 starts with "It" which is a pronoun and needs context. Paragraph 3 starts with "Fishing" which is too specific and does not introduce the topic. Paragraph 4 starts with "You" which is also too specific. Paragraph 5 starts with "You" and is not general enough to be the first sentence.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the text by giving activities to do in Lunenburg. It summarizes the main points about the town and provides a conclusion.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects to Paragraph 1 because it continues to describe Lunenburg. The phrase "It is a beautiful little shipbuilding town" gives more details about the town mentioned in Paragraph 1. This follows the Broader to Specific Strategy.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects to Paragraph 2 because it talks about an important part of Lunenburg's identity, which is fishing. This shows a Logical Order as it explains why the town is significant.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects to Paragraph 3 because it describes the town's historical buildings, which relate to its fishing history. The phrase "as a result" shows a cause and effect relationship.
• Pair 4 (Paragraph 4 → Paragraph 5): Paragraph 5 connects to Paragraph 4 because it gives suggestions on what to do in Lunenburg, which includes the wooden buildings mentioned before. This follows the Topic Example Strategy.
