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 general statement about car accidents in the morning. This follows the rule of Topic Sentence. It does not need any other sentence for context. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, 'For example, Port Macquarie police figures...' starts with 'For example,' which is a conjunction. 'Moreover, the majority of these cases...' also starts with 'Moreover,' which is a conjunction. 'This should draw the public attention...' starts with 'This,' which refers back to something else. 'New method, it is advised...' starts with 'New method,' but it does not introduce the main topic.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it gives a solution to the problem discussed in the text. It wraps up the ideas by suggesting a new method. This follows the Conclusive Words rule, as it provides a final thought on the topic.
