A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first line because it introduces the main topic of the text. It sets the stage for the journey of planning a getaway.

The other paragraphs are not chosen because they do not stand alone. For example, Paragraph 2 starts with 'Booking', which is not a general statement. Paragraph 3 starts with 'A weekend getaway', which assumes prior knowledge. Paragraph 4 starts with 'Researching', which also needs context from earlier sentences.

Concluding sentence: Why this is the last line? This paragraph is the last line because it wraps up the main ideas of the text. It reflects on the overall theme of planning a getaway and emphasizes the need for preparation. This follows the rule of Conclusive Words, as it summarizes the earlier points.
