First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main idea of the text. It sets up the topic of wildlife and how we view different animals. It does not need any other sentence for context. This follows the rule of Topic Sentence. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, Paragraph 2 starts with 'Take', which is a conjunction. Paragraph 3 starts with 'Worms', but it refers back to the idea of wildlife without introducing it. Paragraph 4 starts with 'But', which is also a conjunction. Therefore, they do not qualify as independent sentences.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the main idea of the text. It gives a strong conclusion about the importance of worm conservation. It summarizes the earlier points and shows why worms matter. This follows the rule of Summary Style.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects to Paragraph 1 because it gives an example of the idea in the first paragraph. The phrase 'Take the earthworm' shows that it is an example of wildlife that is not seen as equal. This follows the Broader to Specific Strategy.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects to Paragraph 2 because it continues talking about earthworms. It explains why earthworms do not get a 'cute response'. This follows the Logical Order rule.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects to Paragraph 3 because it gives a reason why worm conservation is important. It shows a cause and effect relationship. The phrase 'But what Darwin rightly recognized' indicates a shift to a more important point about worms.
