A.I. Explanation:

First sentence: Why this is the first line? This sentence is the first because it introduces the main topic. It tells us that there are other ways to find internships. This is a general statement that does not need another sentence for context. It does not start with a conjunction or use pronouns. Why other lines are not chosen? Paragraph 2 starts with "In our digital world," which is a specific context and needs more information. Paragraph 3 starts with "For instance," which shows it is giving an example and needs a main idea first. Paragraph 4 starts with "This best-known job-hunting website," which uses "this" and needs prior context.

Concluding sentence: Why this is the last line? This paragraph is the last because it gives a final detail about using Linkedin. It wraps up the discussion about finding internships online. It does not need more information and completes the topic.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects with Paragraph 1 because it continues the idea of finding internships. It shows that online methods are also good. This is a logical order because it goes from a general statement to a specific example.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects with Paragraph 2 because it gives an example of an online method. The word "for instance" shows that it is giving a specific example of the general idea in Paragraph 2.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects with Paragraph 3 because it continues to talk about Linkedin. It explains more about how to use it for internships. This shows a logical order from the example to more details about that example.
