First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic. It tells us about something that is banned in NSW. This is a general statement that does not need other sentences for context. It does not use any pronouns or definite articles that refer to previous ideas. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, Paragraph 2 starts with 'Wholesalers' which is not a general statement. Paragraph 3 starts with 'Anyone' which refers to people and needs context. Paragraph 4 starts with 'Unless' which shows a condition and needs more information.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it gives a condition that wraps up the discussion about the license. It shows that without approval, the license does not exist. This concludes the topic.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects with Paragraph 1 because it continues the topic of the ban. It explains what wholesalers must do related to the banned item. This shows a logical order of ideas.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects with Paragraph 2 because it talks about the consequences of not having a license. It shows a cause and effect relationship. If someone uses the banned item, they will lose their job.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects with Paragraph 3 because it gives a condition for the license. It explains that a license must be approved. This shows a logical order of ideas.
