A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic. It talks about companies and their orientation for new employees. This is a general statement that does not need other sentences for context. It does not start with a conjunction or use pronouns. Why other lines are not chosen? Paragraph 2 starts with 'In this case,' which is a transitional phrase. Paragraph 3 uses 'You may need,' which is not a general statement. Paragraph 4 starts with 'You may also find,' which also does not stand alone.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the ideas. It gives a final suggestion about meeting with a supervisor. This is a Conclusive Words strategy.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects to Paragraph 1 because it uses 'In this case,' which shows a situation based on the first paragraph. This is a Connector strategy.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 continues the idea from Paragraph 2. It gives specific ways to learn about the company. This is a Broader to Specific strategy.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 adds another suggestion after Paragraph 3. It continues the topic of meeting with supervisors. This is a Logical Order strategy.
