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 moving process. It shows the initial feelings about the move and the challenge of packing. This follows the rule of Topic Sentence, as it sets up the main idea without needing prior context. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, Paragraph 2 starts with "After packing," which needs context from the first sentence. Paragraph 3 mentions "the daunting task" but does not introduce the topic. Paragraph 4 talks about the search but does not connect to the beginning of the moving process.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the moving process. It talks about unpacking and how it made the new place feel like home. This follows the rule of Summary Style, as it brings together the earlier points about packing and moving.
