First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of the text, which is the loss of a grandparent. It sets the stage for the discussion about how this loss affects families and children. It does not refer to any previous information, making it an independent sentence. Why other lines are not chosen? The other paragraphs are not chosen as the first sentence because they do not stand alone. For example, Paragraph 2 starts with 'Children as young as 2...' which refers to children but does not introduce the main topic. Paragraph 3 uses a quote from Dr. Curry, which assumes prior knowledge. Paragraph 4 starts with 'She continued...' which also assumes context from earlier sentences.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the discussion by giving advice on how to help children understand their emotions. It provides a conclusion to the ideas presented earlier about loss and communication.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects to Paragraph 1 because it continues the idea of how children are affected by family changes. The phrase 'Children as young as 2' shows that it is talking about kids, which relates back to the first paragraph.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects to Paragraph 2 because it gives more information about how children cope with loss. The quote from Dr. Curry explains the importance of how parents talk to children about death, which relates to the earlier point about children noticing changes.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects to Paragraph 3 because it continues the discussion about how parents should communicate with children. The quote in Paragraph 4 supports the idea that showing emotions can help children understand their feelings.
