First sentence: Why this is the first line? This paragraph is the first line because it introduces the main topic of the text, which is Jupiter and its size compared to other planets. It does not need another sentence for context. It gives a broad overview of the planets. Why other lines are not chosen? Paragraph 2 starts with "Many of the planets" which makes it not independent. Paragraph 3 starts with "Two of Jupiter's moons" which also makes it not independent. Paragraph 4 starts with "Jupiter has at least eleven other moons" which is not independent because it refers back to Jupiter.

Concluding sentence: Why this is the last line? This paragraph is the last line because it wraps up the information about Jupiter's moons. It gives a final thought about the number of moons and suggests that more may be found. This shows a conclusion to the topic.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects with Paragraph 1 because it continues the topic of planets. The first paragraph talks about Jupiter, and the second talks about moons of planets. This shows a logical order.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects with Paragraph 2 because it gives specific examples of moons. The second paragraph talks about moons in general, and the third talks about two specific moons of Jupiter. This is a broader to specific strategy.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects with Paragraph 3 because it continues to talk about Jupiter's moons. The third paragraph mentions two moons, and the fourth talks about more moons of Jupiter. This shows a logical order.
