A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first because it introduces the main topic of television and its impact on our lives. It gives a broad overview of how life was before television. It does not refer to any previous information, making it independent. Why other lines are not chosen? Paragraph 2 starts with "We even used to read..." which uses a pronoun and is not independent. Paragraph 3 starts with "We have even given up..." which also uses a pronoun. Paragraph 4 starts with "If any member..." which is a conditional phrase and not independent. Paragraph 5 starts with "Whole generations..." which is a general statement but does not introduce the main topic.

Concluding sentence: Why this is the last line? This paragraph is the last because it summarizes the overall impact of television on society. It shows the consequences of addiction to television, bringing together the earlier points about how life has changed.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects to Paragraph 1 because it continues the idea of how life has changed due to television. The phrase "We even used to read books..." shows a shift from past activities to current habits, linking the two paragraphs.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects to Paragraph 2 by showing the next step in the change. It explains that not only do we not read, but we also have given up family meals. This shows a logical order of how habits have changed.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects to Paragraph 3 by showing the extreme effect of television on family life. It explains that talking during a programme is not allowed, which follows the idea of giving up family meals.
• Pair 4 (Paragraph 4 → Paragraph 5): Paragraph 5 connects to Paragraph 4 by showing the broader impact of television on society. It explains that many people, especially children, are affected by this addiction, which follows the idea of family silence during programmes.
