A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of the text. It gives a broad overview of plants that hunt. This follows the rule of Topic Sentence. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, Paragraph 2 starts with "One of these" which needs context. Paragraph 3 starts with "The plant" which is not clear without prior information. Paragraph 4 starts with "The fly" which also needs context. Paragraph 5 starts with "While it is moving" which is a continuation of an action.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it describes the final action of the plant. It wraps up the story of how the plant catches the fly. This follows the rule of Conclusive Words, as it shows the result of the fly's actions.
