A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of fairy tales and their influence on culture. It gives a broad overview without going into details. It does not use any pronouns or definite articles that would need prior context. Why other lines are not chosen? Paragraph 2 starts with "Originated" which is not independent because it needs context. Paragraph 3 starts with "The most telling stories" which uses "the" and assumes prior knowledge. Paragraph 4 starts with "For example" which shows it is not independent as it refers to something before.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it gives a specific example that wraps up the discussion about fairy tales. It does not introduce new ideas but instead concludes the topic by illustrating the point made earlier.

• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects with Paragraph 3 because it provides an example of the metaphor mentioned in Paragraph 3. This shows a topic example strategy where the example follows the general statement.
