First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic. It sets the scene by telling us about the time and place. It does not need another sentence to understand it. It does not use any pronouns or definite articles that refer to previous ideas. Why other lines are not chosen? Paragraph 2 starts with "Upon seeing him," which uses a pronoun and needs context. Paragraph 3 starts with "Monaco and his colleagues," which also uses a specific subject that needs prior knowledge. Paragraph 4 starts with "Amid the strong smell," which is not general and needs context.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the story. It gives a final detail about the situation. It summarizes the events that happened before and provides a conclusion to the scene.
