First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of the text. It tells us about the New Ventures program and where it helps entrepreneurs. This is an introductory statement. Why other lines are not chosen? The other paragraphs do not qualify as the first sentence. For example, Paragraph 2 starts with 'We' which makes it dependent on prior context. Paragraph 3 starts with 'Often' which does not introduce a new idea. Paragraph 4 starts with 'For example,' which shows it is giving an example and not an introduction.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it gives a specific example that wraps up the discussion. It shows how the New Ventures program works in real life. This is a summary style.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects to Paragraph 1 because it continues the topic of New Ventures. It shows how the program has helped by mentioning the money invested and the businesses involved. This is a logical order.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects to Paragraph 2 because it talks about the benefits of the businesses mentioned. It shows that these businesses not only help the environment but also help poor people. This is a cause and effect relationship.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects to Paragraph 3 because it gives an example of a company that helps with the challenges mentioned. It shows how Ecostar works to help people and the environment. This is a topic example.
