First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main idea of the text. It shows a new experience with a camera. 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? The other paragraphs are not chosen because they do not meet the criteria for being independent. For example, Paragraph 2 starts with 'Learning' which is not a standalone idea. Paragraph 3 uses 'Photography' which assumes prior knowledge. Paragraph 4 starts with 'Through' which also needs context.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the ideas presented in the text. It reflects on the overall theme of finding a creative voice through photography. The phrase 'new way to engage' shows a conclusion to the learning journey.

• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 follows Paragraph 2 because it explains how the skills learned in Paragraph 2 lead to storytelling. The phrase 'Photography became' shows a broader idea that comes from the learning process.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects with Paragraph 3 because it shows the result of using photography. The phrase 'Through the lens' relates back to the storytelling in Paragraph 3, showing a logical flow.
