A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of building a diverse sales team. It gives a broad overview of the subject 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 "The reason" which makes it dependent on prior information. Paragraph 3 starts with "This inclusivity" which refers back to something not yet mentioned. Paragraph 4 starts with "Conversely" which shows a contrast and needs context from previous sentences.

Concluding sentence: Why this is the last line? This paragraph concludes the text by showing a negative effect of not having diversity. It wraps up the discussion by providing a contrasting point to the benefits mentioned earlier.

• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 continues the idea from Paragraph 2. It uses the Broader to Specific strategy because it takes the general idea of diverse teams and explains a specific benefit of inclusivity.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 contrasts with Paragraph 3. It uses the Contrast strategy because it shows what happens when there is a lack of diversity, which is the opposite of the benefits mentioned in Paragraph 3.
